If the Grand Canyon represents the geologic record of our time on earth...why is the geologic record of these sediments missing so many time periods?...there are 7 missing time periods in the Grand Canyon....How?
Found:
7 — PERMIAN
6 — PENNSYLVANIAN
5 — MISSISSIPPIAN
4 — DEVONIAN
1 — CAMBRIAN
Missing:
12 — QUATERNARY
11 — TERTIARY
10 — CRETACEOUS
9 — JURASSIC
8 — TRIASSIC
3 — SILURIAN
2 — ORDOVICIAN
You're off a bit. There is Quaternary present- Qal, Qls, Qe, Qg and some Qe. As for the rest of the rocks, I'll dig around. I may have it laying around my yard somewhere. Ya think I oughta take it back? I think it looks so neat holding up my outhouse....lol!
Cretaceous and tertiary are not present because of the level of erosion the region experienced. A number of people have said it's because the Grand Canyon was the primary drainage of the Great Flood that Noah was in. Can't be as the Mayan and Aztecs AND Egyptians would have ben wiped out, and they weren't. The Great Flood is because the Meditterannian Sea had enlarged because of "global warming" that cause galciers to melt. So as it grew, the Dead Sea didn't. Soon the Meditterainin, and I'm unsure of the time frame involved, got to the point it was lapping at the edge of a ridge separating it and the Dead Sea Valley.
Noah wasn't a scientist by any means, but he had a pretty good idea what was happening. So he built himself the Ark. Not making fun of the bible, so please don't think I am. But it is a reasonable theory that Noah saw it happening, predicted through common sense and went ahead and told folks that God told him. Ok, so maybe he didn't like his neighbors all that well....but it has been proven correct by archeological studies of the ruins under the Dead Sea- literally entire towns, buried. Anyhow....
So IF the flood didn't happen globally, how was the Grand Canyon formed? Another government project? :D
So *my* guess on the missing periods is that they are there, but not noticeable. Compare it to the middle of the Pacific Ocean. How much sediment get's laid? Very very little. Likewiase with these formations in the Grand Canyon- deep ocean gets no sediments. And what is laid is not locatable because what maybe several hundred feet of sediment then, after compaction soo becomes maybe an inch or two. Water suspends sediments considerably. Go step in some quick sand if ya wanna see it first hand. Same principle.
I will hunt around and see what I can find on it, though.
