Growing the Geologic Column

When has there ever been a point in earths history when there was no tectonic activity?

Do you know what tectonic activity is? Is every point on planet earth a point where two plates meet? If there is an earthquake in Brisbane, Australia today, would you be able to see evidence of it in Omaha, Nebraska?

There you go. Hell, there is even a town named after that rock type

Extensionally faulted volcanic rocks, ranging in age from about 13.3 million years to about 7.6 million years, overlie the region's Paleozoic sedimentary rocks.[10] The prevailing rocks, which contain the ore deposits, are a series of rhyolitic lava flows[11] that built to a combined thickness of about 8,000 feet (2,400 m) above the more ancient rock.[12] After the flows ceased, tectonic stresses fractured the area into many separate fault blocks.[10]

How about the Snake River Plain Aquifer?

quote:

---

The Snake River Plain is underlain by fractured basalt lava flows, rhyolite, and unconsolidated sediments. Interbeds between the basalt layers are mainly sand, silt, and clay, with smaller amounts of volcanic ash. Within basalts, permeable zones are mainly the tops and bottoms of lava flows, with columnar jointing in between providing slower vertical transmission of water.

Are you scared of research? Edited by hooah212002, : No reason given.

No, it is not. Can you not read? My first example is the source material for the picture. A picture which, by the way, clearly shows a layer of igneous rock between two layers of sedimentary rock. That is kinda what Rhyolite is. Every example I provided was a layer. All three of them. You're just too stubborn to actually read the little bit I provided. It's really not as difficult as you think. It's a Wikipedia article written in the English language describing a town called "Rhyolite, Nevada". it is named as such due to the rocks. You should read what I type. It helps in discussion. No, that is precisely what it is. If you knew how to read, you would see that. But since this material is just a wee bit above a 4th grade level, I can see why you have trouble. The first picture I provided CLEARLY shows a layer of RHYOLITE (that is igneous rock) between two layers of sedimentary rock.Let me break down that wiki article, barney style:

What is above those rocks, Faith? If you said "more rock", you win. What does that mean? That means a layer of rhyolite. What is rhyolite? Igneous rock.I literally JUST learned all this...tonight. Why is it so hard for you? Oh, because you refuse to read things. How do I know that? Because you think I only provided TWO links.As far as the third bit of quoted text, I literally cannot break that down any more. If you can't see that it represents a layer of igneous rock, you really are refusing to learn.Let me give ONE MORE concrete example to add to the list: Blackrock Escarpment

Several welded tuff layers are magnificently exposed in this 1500-foot-high cliff in Bruneau Canyon near the Nevada border. Each layer is rhyolite that erupted explosively from the Bruneau-Jarbidge region, an early active portion of the Yellowstone hot spot. The layers range from 12.7 million years old at the base of the sequence to 10.3 million at the top. They make up the Cougar Point tuff, a volcanic unit widely distributed along the margins of the central Snake River Plain. In a geologic instant some of these enormous explosions erupted many hundreds of cubic miles of rhyolite magma as tiny molten particles that sped across the land buoyed up by hot gasses, blanketing areas more that 100 miles across. Welded tuff layers like these are believed to lie beneath much of the Snake River Plain and Owyhee Plateau.

About a million years ago, just after Lake Idaho had drained away, the near-lake region may have been swampy and certainly had a high groundwater table. When basalt magma rose into this wet environment, as happened many places in the western Snake River Plain, large amounts of steam formed and erupted explosively, blowing out fragments of the basalt magma and the surrounding lake sediments. Such explosions are called phreatomagmatic eruptions; from them are deposited colorful layers of tuff like the ones illustrated from along the Snake River near Grand View. Also shown is the end of a thin basalt flow that was deposited during the phreatomagmatic eruptions. The thinness of this flow shows the basalt lava was very fluid, in contrast to the extreme stiffness of rhyolite lavas that permit only very thick flows to form.

Sedimentary rock layers showing volcanic tuff and rhyoliteCrossing the Shut-Ins, we encountered this cross-bedding in the sedimentary rocks above the rhyolite.I know you won't read a fucking word of this because you are a coward and have no integrity.

Yes, you have. I posted two rather lengthy and well researched posts including exactly that. Just because you are too ignorant to actually read what people respond to you doesn't mean that the information hasn't been presented to you. Ignoring data doesn't make it disappear.

Just because you are geologically ignorant doesn't mean your question hasn't been answered over and over. and over. and over.

I am amazed that every single time someone answers you, you proceed to say you are too tired or you don't feel like reading or it's too hard. You are bar none the most intellectually lazy person I have ever encountered on the internet. I could understand if you were simply a troll (I am holding out hope that you are playing the long con on EvC as it would be fucking epic), but you appear to just genuinely be plum ignorant with absolutely zero interest in learning. That is the sad part: sometimes you give a slight indication that you are willing to do something to hold up your end of the bargain, but then you sully all that with ....this bullshit. One has to wonder what is really gained from all this? This is too long for you to read, so I will cheese jump moons over my hammy while the radar indicates a strong monkey tsunami with occasional spurts of rainbow flavored orange drops. Now, if you actually did read that, then that proves my initial point of utter intellectual laziness because the only time you read is to play the martyr card and you will use this to pretend like I am attacking poor little old Faith.Edited by Adminnemooseus, : NOTE - 24 hour suspension for this message - Adminnemooseus
