Author | Topic: Rapid generation of layers in the GC | ||||||||||||||||||||||||||||
Tranquility Base Inactive Member |
Here's extracts from mainstream sedimentology texts I dug up myself last (southern hemisphere) summer on rapid formation of layers and also one quote I found on the internet from a geology journal:
quote: I'm not trying to say this necessarily proves anything but it is part of our 'thesis'. It certainly proves that mainstream researchers are willing to admitt that layers do not have to represent annual/seaonal bands or even point to great age at all. ------------------You are go for TLI

Here's a quote from a mainstream journal, presumably from a mainstream geologist chiding his fellow geologists to take on some more catastrohpism back in 1972 (it sounds to me anyway). He's talking cyclothems and polystrate fossils:
quote: I admittedly found this one on the Internet but I don't think a context is necessary is it? Go read the article if you need the context. I'd be interested if this guy got sacked or not or was ever allowed to publish again Again all this proves is that what used to be thought of as taking millions of years has in some instances, even by mainstreamers, been agreed to have taken only a matter of hours/days/weeks. Millions of years reduced to days. And of course Austin et al would immediately, for good reason, point to the flood and floating mats. Of course it could have been a huge non-Noah flood but it still begs the question that if thousands of feet of the GC are at least possibly due to a big flood then maybe the creationists have a point. ------------------You are go for TLI [This message has been edited by Tranquility Base, 05-17-2002]

quote: Are you actually comparing varved sediments to storm deposits, or mudflows, or other local catastrophic sedimentation events? Do you really think that geologists have not thought about these things? Do you really think that catastrophism is not recognized as part of the uniformitarian concept? You see, this was all explained to me in my very first Geology course. That's something you miss by going straight to the professional papers and monographs ... the background to be able to critically analyze what you read. As a result you have been sucked in by the professional creationists who give you only a part of the story. I am sorry that they have taken advantage of you.

I think you are missing the point. No one on here, to my knowledge, has said that every layer of sediment MUST form slowly over eons of time. Some don't and you are not getting a quibble about that. What you have done is make a giant leap (sans evidence) that ALL sedimentary layers were laid down quickly. That you have provided no evidence for whatsoever! Not one of those quotes suggests that all sedimentary layers are laid down in seconds or minutes. Further, this in an 'invented' controversy on your part since I doubt you can find one geologist who will say that every layer takes eons of time. But, let's look at some that DO take time. The navajo sandstone is a mega cross-bedded unit.
Here is a photo I took:
The Navajo is a late Triassic-Jurassic sandstone with wind directions alternating from the N to NW and it contains rare reptilian tracks. This is overlain by the continental fluviatile Morrison Fm and finally by Cretaceous marine sediments and finally by coal beds. Here's where the problem comes in for a flood scenario of Cambrian-Cretaceous age. All of these units contain reptilian fossils with the exception of the marine sediments (which interfinger with continental ones). Most importantly, these coal beds contain dinosaur trackways that are in beds above what many consider the end of the flood. Why is this important? Well, assuming the flood took one year and there were two dinosaurs on board, and the boat landed in Turkey, then it does not leave much time for the dinosaurs to repopulate the earth and walk around in the vegetation mats left by the flood. Any explanation for these observations? Can you also tell me about all the flood waters that occupied the same area before the dune deposits? None of these observations make sense to me in terms of a singl Noachian flood. Cheers Joe Meert refs: Hintze, L.

There is a lot of variability there. I've been told by a LDS that I know that "evolution is a dirty word around my church" yet BYU's biology department teaches evolution and a church pub I read interviewed a BYU biology prof who said that evolution and BBT do not contradict their beliefs and then he went into a whole 'religion and (mainstream) science are friends' discussion. In fact I suspect that the natural science academics at BYU are probably having a large moderating effect on the entire church.
It is clear that so far YECism is not officially proscribed by the LDS church (neither is theistic evolution) but as many of their congregations are taught by laypeople (no professional preachers) Protestant Biblical literalism and therefore YECism is naturally going to infiltrate at least the lower levels of the church on an individual basis. However because the church accepts continuing prophecy a single declaration from their president could turn everything around instantly. Their future position is uncertain. A similar example is this; you frequently point out that Catholic schools teach evolution, but I know there are some Catholic YECs running around despite this.

"I think you are missing the point. No one on here, to my knowledge, has said that every layer of sediment MUST form slowly over eons of time. Some don't and you are not getting a quibble about that."
--He didn't assert this at all as a 'must', but as something that should be considered. "What you have done is make a giant leap (sans evidence) that ALL sedimentary layers were laid down quickly. That you have provided no evidence for whatsoever! Not one of those quotes suggests that all sedimentary layers are laid down in seconds or minutes."--He didn't say that this suggests that all sedimentary layers have been laid down quickly, but attempted to give support on his assertion that there isn't much of a problem with rapid depositions. "The Navajo is a late Triassic-Jurassic sandstone with wind directions alternating from the N to NW and it contains rare reptilian tracks. This is overlain by the continental fluviatile Morrison Fm and finally by Cretaceous marine sediments and finally by coal beds. Here's where the problem comes in for a flood scenario of Cambrian-Cretaceous age.

"Can you also tell me about all the flood waters that occupied the same area before the dune deposits? None of these observations make sense to me in terms of a singl Noachian flood."--Think I need some emphasis, or clarity. Not sure what your asking. ------------------

quote: However, there is an implication that this is evidence that the geological record could be formed in a one year flood. If you do not believe this to be the case, I suggest that you make that clear and also have some words with the professional creationists who misuse this same information.
quote: No geologist has ever said so. So what is the point?
quote: You still have the same problem. In fact, you have less time to repopulate the earth.
quote: I think Joe is asking where did the flood waters go so that you could have eolian deposits in the middle of a global flood.

quote: JM: Then you have an even bigger problem! If the Cretaceous marine deposits are not flood evidence, then where are they? That's the end of marine deposition in the region.
quote: JM: There are other (older) marine-terrestrial transitions in the strata out west. Apparently, this is one region where one could escape the flood. Maybe all the flowering plants, dinosauars etc were headed to Utah? Maybe the Mormons are on to something living there. Cheers Joe Meert [This message has been edited by Joe Meert, 05-18-2002]

--At the end of marine deposits didn't you state that there are coal beds above these? "JM: There are other (older) marine-terrestrial transitions in the strata out west. Apparently, this is one region where one could escape the flood. Maybe all the flowering plants, dinosauars etc were headed to Utah? Maybe the Mormons are on to something living there."--I'm not too knowledgable on this area and its geologic compositions and all, though it seems to me that there simply were periods where marine deposits were made and when terrestrial area appeared, eolian dunes were created? ------------------

As I said, you are faced with the peculiar feature that dinosaurs either quickly repopulated a still flooded earth or they were not killed in the flood. Lucy, you've got some splainin to do!

"JM: Yes, coal beds are not marine (or we have swimming dinosaurs leaving footprints!)"
--That's what I thought, but I had some speculation on whether there was another event later on in geologic history in which Marine deposition occurred. So lets see, why is this not simply explained by the fact that marine sediments were deposited as this area was submerged, and then after waters abated form this area, suspended vegetation settled and was later consolidated into coal? Seemingly according to the data given, this is what it indicates. "JM: So, you have multiple flood events in your single Noachian flood? As I said, you are faced with the peculiar feature that dinosaurs either quickly repopulated a still flooded earth or they were not killed in the flood. Lucy, you've got some splainin to do!"--Well no, there weren't necessarily multiple floods, and neither were the flood waters themselves direct causes of the extinction of the dinosaurs and similar animals. Though because this flood was effective on a global scale, topography as well as rapidly evolving topography, currents, and other causes of water distribution and elevation play factors in where and and at what time isolated areas would become submerged or appear terrestrial. ------------------ [This message has been edited by TrueCreation, 05-18-2002] [This message has been edited by TrueCreation, 05-18-2002]
