PALEOSOLS AND WHY FAID'S LINK DOESN'T HELP LONG AGERS
Quote | Now you guys seem to have some example in mind where ALL the roots are in the right direction. Would someone care to show me an example?
That's what we've been saying all along, Davie-doodles. Don't have one from the Grand Staircase handy, but here's a great one:

Looks to me like a big clump of plants that got uprooted by the rising, rushing water of Noah's Flood, floated around for a while, then came to rest and was buried with a bunch of water-borne sediment. As the water receded, the sediment got eroded so we can now see it. I've seen bunches of plants like this floating in an upright postion. It's simply a matter of center of gravity and buoyancy.
What's YOUR explanation? In detail. I know you say it's a paleosol. But tell me the whole detailed story of how you think this soil formed, how the plants go there, how they got fossilized and so on.

In this one, look at figures 4 and 5:

Your turn, Davie, show us some photos of paleosols with upside-down and sidweways and randomly oriented root traces. You're the one with the better explanation, remember? |
I'm squinting really hard and I'm not seeing anything in Figures 4 & 5. Can I borrow your magnifying glass?
As for showing you some trees in other-than-upright positions, how about this ... didn't someone say "ALL PLANTS ARE DEPOSITED UPRIGHT" ?? Well, if you said that, I think you are sadly mistaken ...
From Faid's article ...
Quote | The YEC hypothesis that the sedimentary record originated as a result of a single, year-long global flood is directly contradicted by the presence of a variety of biogenic structures preserved within the sedimentary record which could not form in the time allotted for the flood, or under the depositional conditions associated with the flood. One type of structure that could not form via the flood is "fossil forests," containing upright trees preserved in growth position. | Why can't we have fossil forests buried by the Flood? Actually this is a prediction of the Flood Hypothesis. If a Global Flood happened, we should have all kinds of things happening to plants: plants getting uprooted, transported, redeposited; plants getting buried in situ; plants getting buried sideways and upright ... maybe even upside down! This is a naive statement.
The first paragraph from Faid's article actually confirms my statement above! See below ...
Quote | 1. Eocene Fossil Forests in Yellowstone National Park
The Lamar River Formation in Yellowstone Park contains the best known example of a "fossil forest." Here we find multiple levels of in situ trees. The upright trees at Specimen Ridge are rooted in fine-grained tuffaceous sandstone and encased in conglomeratic mudflows. The grain size of the conglomerate decreases away from the location of the volcanic source areas, the East and West Absaroka belts. Also, the ratio of upright, in situ trees to horizontal trees increases away from the Eocene volcanic source areas - the eruptions and mud flows flattened whole forests proximal to the source, while many trees are preserved in growth position in more distal locations, such as at Specimen Ridge. Although it is unclear how many successive forest layers are present in the Lamar River Formation, estimates range from 9-12 for Specimen Ridge. Some of the levels have very wide and old trees trunks.
The mud flows caused by the Mt St Helens eruption in 1980 provide an excellent analogue for the geologic processes which produced the Yellowstone deposits. Fritz noted that the mixture of transported of upright and transported trees found in mudflows were virtually identical to the deposits seen at Yellowstone. In fact, several 'recent' fossil forests, containing in situ trees up to 7m tall, are present in the vicinity of Mount St Helens, each buried by lahar flows and/or pyroclastics. Exposures of these were exhumed by mudflows after the 1980 eruption. Most of the forest-bearing deposits have been dated to the period 1479-1857 by tree ring analyses of buried trees. These subfossil 'fossil' forests are excellent modern analogues for the Yellowstone forests exposed at Specimen Ridge. Karowe and Jefferson note that the "striking similarity between features of of trees buried in situ by Mount St Helens mudflows and features of upright fossil trees in the Specimen Ridge section of Yellowstone National Park strongly supports a depositional model of in situ burial for the upright trees at Yellowstone" (p. 203; see also Yamaguchi and Hoblitt, 1995). |
What is the author referring to? Well this, of course, which I posted previously.
Oh, and guess what. After Mt. Saint Helens, they changed the sign!!!
Again, guys, you would know all this if you would expand your minds and read some creationist books for a change. You've been propagandized all your lives that creationists are evil, lying, money hungry morons, who want to take everybody back to the Dark Ages. The truth is that creationists have many right answers. And mainstream science slowly catches up to what creationists often have been saying for a long time. Again, as I have said before, it is often the creationists who are "at the tip of the spear" in science. But to be at the tip of the spear is many times a very lonely place. It is not for the faint-hearted. It is not for people who seek approval from others. It is only for courageous, independent thinking people who want the truth about everything no matter what the cost.
Now the rest of the examples given in Faid's article are basically repeats of the Yellowstone situation, which, of course, is exactly what we would expect if there was a Global Flood. We would expect to see MANY buried forests all over the world. Many trees would be buried in situ and many would not be.
Now ... please tell me again what was your point, Faid, in giving me this link? I guess I really do not understand the Official Millionsofyearsianism Viewpoint on Paleosols. This link seems to help the case for my Global Flood Hypothesis far more than it helps any other case. But again, I really don't fully understand your case in the first place, so maybe you could clarify.

QUESTIONS AND ANSWERS
Deadman... Quote | This is how fossil confirmation of radiometric dating works, Sweetcheeks....given that there are dates on the morrison of about 145-158 mya, what kind of fossils can we expect to find in those layers?
Why are there no modern mammal fossils mixed in the layers as your 2350-5000 BC flood would require?
Let me repeat this very slooowly, stupid. WHY ARE THERE ...NO MODERN MAMMALS IN THE MORRISON? | Well, just a guess. I'll have to study this when I am done studying paleosols and the Grand Staircase. But my guess is the reason is because the mammals that ARE buried there were buried 2300+ years ago and they became extinct because of this humongous catastrophe (subliminal ad: global flood, global flood) that buried them. The only mammals left alive were those on the ark, and they in turn, reproduced and diversified after leaving the ark. We would expect them to be different from the mammals that got buried, would we not? Again, just a guess. Maybe you could fill me in with more specifics so I could analyze this better. I'm not sure if you are saying "there are no mammal fossils at all" or "there are just no MODERN mammal fossils."
Eric... Quote | Half the western United States was underwater at one point or another, and 10 million years ago California didn't even exist—all of it was underwater. | You're getting closer to the truth. Actually, ALL of the US was underwater at one point. And you are off on your dates, but at least you are starting to recognize the role of massive quantities of water.
JonF... Quote | Er, Davie-moron, that's the conventional geologist's viewpoint. The "hardened, THEN eroded, turned into mud and deposited" idea is your fantasy. | No. Actually this is Faid's fantasy of my supposed fantasy. Not to be confused with your fantasy about my supposed fantasy that a tuff is a sedimentary rock. Apparently I should not confuse all these with my fantasy about your supposed fantasy that you at one point said that lava was a sedimentary rock. And don't forget Incorygible's fantasy about how I said Leakey led an army of paleo-fascists on to a bloody victory. Oh ... I keep thinking of fantasies. How about the biggest fantasy of them all? MILLIONSOFYEARSIANISM. I think we need a Fantasy Librarian around here to keep all the fantasies straight. Any volunteers? :-)
Crabby-- So are you coming or not? I can't figure out from your posts if you are or aren't. Am I buying you lunch? Or are you just going to walk in and yell at us?
