Re: Being a bit easy
I do believe the flood scenario is very reasonable, and it is frustrating to me that it isn't obvious that, for instance, the flood does very nicely deal with the broad facts of the worldwide geologic column and the existence of worldwide fossils, but obviously defending it will take more knowledge than I have at the moment.
Maybe you need to find some evidence that is diagnostic of the flood. I mostly see that you have been presenting evidence that does not support the flood in an exclusive way.
In the meantime, the flood does not account for eolian deposits, evaporite deposits, terrestrial trace fossils, etc., etc. These items will demand that you come up with some pretty convincing stuff. You will certainly need something more compelling than the 'clams in the Himalayas' argument. That won't wash around here.
I don't find them convincing or relevant to the points I've been trying to make. They don't deal with the reality of the appearance of the geologic column as I understand it, and we are all just talking at cross purposes. But I do understand that if I'm going to make any kind of believable case I WILL have to learn about these processes.
Some of us here have studied the geological column for decades, at least. Believe me, your arguments have been forseen and dealt with many times before. In fact, many of your points have been brought up in early geology classes as logic exercises.
Since this is a general post even though it started as a reply, I'd say to the person here who said he started out a creationist that I started out an evolutionist, read Darwin, enjoyed reading articles by Stephen Jay Gould and that sort of thing, but kept being frustrated with what seemed to me a lack of evidence for its basic assumptions -- simply accepted it all on faith nevertheless. Some time after I became a Christian I started reading the creationist literature and found it expressing the same frustrations with the ToE I'd always had, and actually giving great alternative answers.
Yes, I've known people who have problems confronting the uncertainties of geological thought. Some have had a near-violent reactions. Believe it or not, it all makes sense. THat is because it is not based on faith, but upon solid inductive reasoning and testing by independent techniques.
There you have it. I'm going to try to stay away and not come back until I know more.
I am sorry that you are leaving. In this post, you have expressed a more humble approach, which is (unfortunately), uncommon among our more outspoken YEC contributors; who seem to know, not only all of the science, but every thought and motivation of evolutionists.

Re: Thank you Faith
Having just read thru most of this thread it is apparent to me that Faith is working under the assumption that the "geologic column" shown is geo textbooks is exactly what is found uniformly, all over the world.
More accurately, it is what many YECs think the geological column should be; or what they think we believe it is.
She needs to be shown that the "geologic column" is nothing more than a representation of how differing layers from differing parts of the world all add up.
I think Moose cleared this one up nicely. It is actually a graphic representation of a timeline. It lays out geologic time in a sequence of relative ages. This is opposed to what we call 'stratigraphic columns' which are actual representations of the geological record at a given location and are often fragmentary.
She seems to be working under the assumption that the world is composed of straight uniform layers that exist everywhere and that when paleosols are mentioned you are talking about topsoil, as it exists now, that can be suspended in water and deposited as something you still recognize as topsoil.
This is a grossly oversimplified viewpoint that is commonly promoted by YECs who contradict themselves by simultaneously discussing the incompleteness of the stratigraphic record.
Stratigraphic continuity of units is an ideal situation rarely realized at any given scale. The 'vast, continent-wide layers', supposedly indicative of a flood deposit are broad generalizations that break down on detailed investigation. And no, there is no known way to transport a soil by moving water to a new depositional environment and have it remain a soil.
Could one of our wonderful geologists give a layman's account of what is shown by the "geo column" and what is actually found in real life?
I think that between Moose and Ned this has been done, unless there are some specific questions.

Just for info, my picture of the GC is not from diagrams in books, it's from photos of places where the strata are visible all over the world, as well as places I've seen in person, from the Rockies to the canyons and formations of the Western deserts. Of course there are exceptions and variations, but overall they are awfully straight and parallel for something built up gradually over time. But I'm gone, not arguing this any more.
This is exactly what we would expect from seas moving back and forth across the continent. But in the case of these sediments, there were also emergent land masses, which is why we see fluvial and swamp deposits along with beach sands and eolian sand dunes.
By the way, it is interesting that an actual time-stratigraphic horizon cuts across the layers that we see megascopically in these photographs. But of course, we probably wouldn't know that if we didn't have evolutionary models to compare with depositional models.

But at the moment I just have to ask: Would it kill you all to suspend your detailed scientific knowledge just long enough to allow you to see the worldwide appearance of the geologic column from a layman's point of view and realize that it DOES LOOK like something that could have been created by a gymongous flood?
What would kill us is trying to figure out where to start the explanation. I agree. To the layman it looks like a big deposit of sediments haphazardly piled up on the surface of the earth. However, there are patterns that one cannnot ignore. These patterns are created by processes. We can see most of these processes at work today creating identical deposits. However, explaining all of these process, deposits and events is not a trivial task to be carried out on a message board. There are so many nuances and so many exceptions, suffice it to say that a young geologist is probably not really a geologist. I know this is not very satisfactory for you, but that is why you get all of these suggestions to 'get an education.'
I have no good solution for you. I know that you will not simply accept what we say and I wouldn't want that either. Most of the time we just hope to shut up the militant YECs or make them think twice before making the same argument. But how do we deal with someone who has legit questions?
Laid down by water, warped and upended by later events. That acknowledgment would help a lot.
Yes, but I'm not sure what you mean here.
Let me guess: yes, it would kill you, a ton of objections to follow. But thanks for any efforts in that direction.
Not really any objections. In fact, I think that asking questions is the best path to knowledge. The problem here is the format of the discussion.

Re: A creationist's question
How do you account for the fact of such even depositions over millions of years in such nice straight horizontal layers as are seen in the Grand Canyon BEFORE a river comes along and makes a canyon through it all?
The river doesn't have that much to do with it, actually. All of these sediments were deposited on the continental craton (basement rock) as seas, deserts, beaches, swamps and coral reef environments moved back and forth across it. This is not uncommon in the geological record. There was no major structural disturbance until the uplift of the Colorado Plateau and in that, the region was uplifted as a block. Was the depositional surface even all of that time. No. In detail we can see sand dunes and stream channels, but basically the terrain was fairly flat.
quote:
Millions of years of undisturbed layering of various sediments, and then this disturbance of a river cutting through it?
Well, why not? The region suffered very little tectonism and remained near sea level until the Tertiary, then it became possible for a canyon to be cut.
Big change at the end of the building-up process apparently. How do you account for it?
The region was not near any active plate boundary until that time. Why shouldn't sediments simply be deposited for an extended length of time. By the way there were periods of erosion as well. They simply don't show up well because of the low relief of the region for most of the last 500Ma.
Similar situation where you can see the strata thrust up at angles in mountains. Do you posit the same many millions of years in the building up of those strata?
Yes. But don't misunderstand. A single unit may be deposited abruptly, though not always.
Are they the geological column itself simply upended?
No. The stratigraphic section at that locality was tilted.
And the same question as the first one: How do you account for such an enormously long period of building up of the strata BEFORE the great upheaval of the mountains which put the originally horizontal strata at angles to the horizon?
Normal continental deposition. It's going on right now in many parts of the world.
Why was the earth so quiet for so long that the strata could form in neat parallel layers of sediments, and then all of a sudden or so it seems we see all this activity - the cutting of a giant canyon, the upthrusting of mountains. How do geologists explain these phenomena?
Is there a time limit on this type of sedimentation? I don't know of any. It is occurring now all along the eastern coast of North and South America. Been doing so for some hundred million years, in fact.
I think your problem here is not a lack of knowledge so much as simple incredulity. You cannot fathom it, therefor it is impossible.

Re: A creationist's question
Why would evolutionists suppose that we could extrapolate from the everyday processes we are observing right now to the processes involved in a one-time catastrophic worldwide flood?
The short answer is that we do not presuppose a worldwide, biblical flood. We let the evidence lead where it may. The evidence does not give us a whiff of a notion that there was ever such an event. This was discovered by YEC geologists, by the way.
That seems to be the answer to every creationist observation, but no creationist supposes that anything like our normal geological processes could apply to such a cataclysm.
If you have a description of a geological feature we should see resulting from such a flood, that does not also support normal mainstream events, then please let us know. Usually, YECs are asking us for what those features might be.

Re: A creationist's question
So MILLIONS of years of relatively quiet stratification occurred everywhere, ...
Read closely. I never said this.
...but at least in all the places where we can see it (an awful lot of them) and THEN very recently disruptions came along, rivers cut through them, tectonics made mountains of them, erosion wore them down etc etc etc.
No. There were many disruptions around the world. Some places, however, remained quiet. I'm not sure why this is hard to understand.
I agree, that's how it had to happen. It's accounting for the long period of quiet that seems difficult considering all the activity we have today. Tectonic movement is a very recent thing, didn't happen for those millions of years, right?
No. Tectonism is common throughout the geological record... just not everywhere at once. At the GC it didn't happen for many millions of years. Prior to that there was plenty of activity. If you've ever looked at the deepest rocks in the canyon, you would understand.
Somehow the earth just got active recently, while for millions of years it was amazingly quiet. Then in spite of all the observable activity now, quiet deposition is considered to be occurring that could go on for another millions of years? OK. You have an answer. Thank you.
No. You sound confused. And frustrated. I think I have explained this before. If such tectonism were so widespread as you seem to think it should be, then what has happened at the Bahamas Bank in your lifetime? Mountain building? Earthquakes? How can you say that tectonism is a 'recent thing'?

Re: The flood's effects
I certainly wouldn't offer a miracle for an answer in any case. The Bible does hint at very different geological circumstances both before and during the flood from our own though, and creationists work from them, though of course they would have to be verified scientifically. No rain before the flood for instance, no high mountains, just low hills, ...
Then you need to explain the references to 'high mountains' before the flood in the bible.
... water occurring as a mist that comes up from the earth,...
So, there can be mist that rises, but no rain. Very interesting. I think you may want to check your version of the bible.
... "fountains of the deep" being opened up to provide much of the quantity of the flood water, ...
Which there is no evidence to support.
...something that could be so deep there's no way to detect it yet, even under the sea floor, if such a deep sea floor even existed then*, and the "fountains of the deep," whatever they were, don't exist now anyway to BE detected. But this is just for creationists to muse about.
I guess so. It is very convenient for them that the evidence is gone.
*I get chided for applying my own imagination to these things, but here's another thought: the opening and emptying of "fountains of the deep" could have caused the lowering of the sea floor, much increasing the volume of the seas, and accounting for where the water went after the flood.
This is isostatically prohibited, but other than that, it is very imaginative. Is there evidence of all this tectonism in the bible?
All that seafloor activity could have something to do with activating the tectonic plates eventually too, which built the high mountains.
Other than the fact that the bible mentions high mountains, YECs have another problem. There is strong evidence that mountain ranges are of very different ages...
The Bible says that the earth split apart later on. Just my imagination though, don't know if creationists have such an idea, not that anyone here cares anyway since there's no way to prove any of it, which I grant.
As for the layers, and the expectation of a clear layer where the flood occurred, the model is that the entire geologic column was created by the flood. It IS the evidence of the flood.
If so, this doesn't help you. It is also evidence for normal mainstream explanations of the geological record. What you need is something that is diagnostic of the flood.
It IS the "sharp layer in the geologic record [that] ...should be world wide, very thick and well marked."
Well, I can probably think of a hundred sharply defined events in the geological record. All of them regional and not worldwide.
But if it is really true that you see exactly the same kind of layering of sediments ongoing now ... but let me ask. Is there proof of this ongoing layering that everyone keeps referring to?
There is very strong evidence. For instance, coral reefs look identical in morphology and lithologies to many of the ancient reefs, at least back to the middle Paleozoic.
I don't mean simple accumulation of sediments, that's obvious. I mean can anyone show me LAYERING of DIFFERENT sediments, just as we see in the GC, that is very new?
Sure. We see deltaic environemnts like the Mississippi River delta in the record; fluvial deposits that are virtually identical to those of the Mesa Verge Group, pelagites and cherts identical to the record; evaporites with dessication features.... Almost any geology text will give examples.

Re: A creationist's question
This is especially interesting information. Meant to comment on it in my last post to you. Running water is laying down permanent layers of sediments. Something to think about.
Yes, they are. I see outcrops of the Denver Formation practically every day that look identical to fluvial sediments in the stream cutting through the section (excepting for the trash and construction debris).
How deep are these layers by the way?
Do you mean 'thick' or 'deep'? I don't believe there is any practical limit to the depth. Certainly the Mesa Verde fluvial section is hundreds of meters deep. The thickness of any channel can be as little as centimeters.

Re: The flood's effects
There's no mention of "high mountains" before Deuteronomy which refers to a time some 1500 years later. "Mountains," however, are mentioned in the flood itself:
All I can say is:
quote:
Genesis 7:19
"They rose greatly on the earth, and all the high mountains under the entire heavens were covered."

But I don't think they try to prove such things as they can't be proved, can merely be given as the model from which they work.
You are being generous here. YECs demand proof of evolution from us. Wouldn't that be a bit hypocritical?
We're already covered this. Please get the context here. I am NOT arguing any of this. I did NOT want to argue the Flood at all and I am not arguing it now. I am simply reporting what I understand to be the creationist view, in order to answer some confusion about different creationist views.
Okay, then. THEY need diagnostic evidence.
That wouldn't contradict the idea that the total GC was created by the Flood. One would expect local effects
Not the point. The point is that there is no definitive flood sequence in the geological record. There is a reason for this.
Is this an example of layering of sediments?
(regarding coral reefs in the geological record)
Yes. And lateral facies changes. And basic morphology.

Re: Up until now I've stayed out of this but I can't allow this to get by.
I've stopped arguing any of this but you don't seem to be getting my point so I just want to get it across if possible: It is very striking that such evenly horizontal parallel strata of the geo column, which describes the character of the column to great depths over an enormous swath of the earth, could have survived millions of years as undisturbed as, say, the formations of the Southwest US --which were clearly undisturbed until quite recently when erosion has exposed all those neat parallel layers to great depths.
We've stopped arguing any of this as well. Perhaps I could just point out in as clear as possible terms that while it is very striking to have large areas of apparently conformable sedimentation, it is NOT AT ALL a large swath of the earth, nor is it unusual or unexplained.
It is apparent to me that you have decided to pay no attention to our posts and this I consider to be disrespectful.
I guess it could happen, certainly, for many local reasons, but I'm struck by the amazing serenity that had to prevail for millions of years in order for the layers to form so neatly and parallel and horizontal in the places where that is certainly the case.
And I am struck by the amazing ability of YECs to dismiss logical arguments by professionals in the field, as simpy 'unbelievable'. You have been treated with a lot of patience here, but your constant, tedious repetition of an argument from incredulity, and numerous trite strawmen, will not cut it any more. Do you really think that geologists have not thought about these things? Do you think it's all just 'made up'?

Re: Paleosoils, Palaeosols
So, Faith, how's the studying coming along?
quote:
Listen, the whole creationist picture of the Flood is that incredible quantities and varieties of Stuff were carried in the flood and deposited in layers.
That's it? Not much detail...
quote:
There's nothing more unusual about topsoils being carried with water currents than the other sediments, and a bazillion dead creatures along with them all. And topsoils with plant roots it seems to me stand a particularly good chance of being carried intact, not to mention that I've seen soil float, haven't you? It doesn't absorb water rapidly if it's organically rich.
You really want to stick with this story? Do you understand that transport is just part of the issue? You also have to pick up the soil from a place where it is attached by roots to the substrate? Then you have to move the mass, intact, by raging floodwaters some uncertain distance enduring storms, waves, and currents. Then you need to have some depositional mechanism to deposit the soil intact (did you ever see a strip of sod wash up on the beach?). Then, if we go by Randy B's story on another thread, you have to deposit the soil with the trees, also intact, in such a way that the trees remain upright as the waters recede so quickly they can carve the Grand Canyon!. Now, call me skeptical, but to me, this is a bunch of, well, ... 'not soil'.
quote:
There is no flood we see today that can possibly be used as a model for the Big One that must have dissolved unbelievable quantities of terra firma and redeposited it somehow or other IF IT OCCURRED OF COURSE.
That's the whole point, isn't it? How far can you stretch your credulity for this when you have a hard time accepting conformable sedimentation on the top of a stable craton?
quote:
And tidal action which would discriminate between layers is a FAR better explanation for what is seen than any time-defined notions of how the strata were formed.
Sorry, but tidal action would far better explain the destruction of soils than their discrimination, transport and redeposition. Remember, this is the BIG ONE! Or is it the gentle-violent, wet-dry, rapid-slow, hot-cold flood. At some point, you need to make a decision on this.

Re: Other explanations

Ummm, no. If you reason that soils can be picked up, transported by raging currents and then redposited on a far shore, intact; you reason poorly.

My reasoning I daresay is better than half the contributors to this thread.
Again, manifestly, no. You chastise JonF for asking about 'igneous rocks' and 'layers' when they were not in your previous post. But this is just an example of how you choose to ignore certain types of data that conflict with your story. You seem almost proud of the fact that you do not know about pertinent geological evidence.

Re: Taking a Step Back
I don't agree. Certainly most creationists who come here are ignorant of science and evidence, but that's not why they hold the views that they do; if it were, they'd change their minds (as a few do) when they learn.
True enough. My take is a bit different, however, in that I can understand ignorance and even willful ignorance. The problem with this thread, to me, is the constant repetition of the same argument from incredulity extending for page after page with no elaboration or supporting evidence. There is hardly an acknowlegement of the counter arguments, except to frequenly misrepresent them. The appearance given is one of simple combativeness. I really don't think Faith has paid any attention to our points even though professing a commitment to learning more about geology. Having said all this, in the spirit of avoiding the appearance of more piling on, I will refrain from further comment on this thread, except as technical questions come up.
