Quote:Not sure what any of FM's comments have to do with the rate of erosion of the falls.

My dear friend, youve unknowingly merely stated what geomorphology has been saying all along, the Niagara Falls are remnant of Wisconsin Glacial meltwater, so the age of 10 to 12000 years is about right. In that respect, Im not suire why youve posted all that, were you assuming that geology only dels with Paleozoic rock?
Quote:Why are these deposits often under extreme pressure
. And what does that have to do with ages of the earth? Im curious where you get your stuff?. Much oil gets pressurized in post diagenetic (formation mechanics) tectonics. The strength of materials issue is that many formations are overpressured when the oil migrates and formational boundaries do rupture, but they dont wait around, they rupture as a function of Darcy's law
