Talk:Law of superposition
From Wikipedia, the free encyclopedia
Removed the following quote from article pending source information.
- in a series of layers and interfacial features, as originally created,the upper units of stratification are younger and the lower are older, for each must have been deposited on, or created by the removal of, a pre-existing mass of archaeological stratification.
The implication was that it was a quote from Steno, but the wording doesn't seem to fit. Provide source and re-insert. (also fixed minor typo mush --> must). Vsmith 01:34, 19 January 2006 (UTC)
[edit] Examples of reversed sequences
- 1--The edge-layers of an Impact crater, can have an overturned sequence of rocks. It's still in the same sequence, just up–side–down, (the layers thrown radially outward, and overturned).
- 2--A Thrust fault can also produce an up–side–down layer of rocks. (It can be a trait of the particular fault in question.)---MMcAnnis...Mmcannis 18:21, 27 January 2006 (UTC)
[edit] Shark teeth (fossils) embedded in sed. rock
- I found a shark tooth in a 2 Million yr old cliff, with the 2 mill Sanddollars that the cliff contained. This(a 1 unit Field Paleontology class following a 3-unit class), was at El Golfo, in Mexico, south of Yuma, Arizona (extreme SW, on California border). I just started reading the Nicolas Steno article. WoW, as to how he started. It is fantastically amazing that the religion debate will continue long after every single one of us who reads any words here, are looooonnnggg gone. (Darwin even wrote to Alfred Russel Wallace, and stated the exact same thing, (in reference to the stage-floor, public debates, which were the method of debating "ideas" in the 1850's, and in reference to a particular "Frenchman" who was his Antagonist for years). End of note. Steno must have been conflicted, to have always been fighting the 'religious battles' of his life.Mmcannis 21:38, 27 January 2006 (UTC)
The shark teeth in stone, is where he started ! (And, I had cupped my hand below a soft spot on the cliff, 8 ft up, and about 3 fossil items fell into my palm(1 the small,shiny tooth!)....hhmmm..."try to make it real, try to make it real, but compared to what, (from the song))---MMcAnnis,YumaMmcannis 21:38, 27 January 2006 (UTC)
