Dating Methods Geological Global Flood Philosophical


Megasequences are repeating layers of flood waters: conglomerate, sand, shale, and limestone (then unconformity) as materials become sorted by water based on weight and settling. The five Mega-sequences found on earth are supposed as billions of years of geologic time however, these may also be explained by changing sea levels as global flood waters passed over the continents and receded, then repeated.

In a megasequence the grains decrease in size from boulders at the bottom (conglomerates) to tiny grains of lime at the top. This “fining upward” suggests the ocean currents were very intense at first, and then the waters slowed down. The heaviest material dropped out first, followed by lighter materials (sand and then clay), until only the finest grains (lime) were left. But why did this happen several times?
Megasequences are separated by flat, eroded surfaces, called unconformities. To erode a flat surface across the entire continent means the ocean water was incredibly energetic. As the waters slowed down, they deposited another megasequence on top of the unconformity. This process was repeated.
