GENERAL GEOLOGY

Detailed explanation-1: -Adirondacks, Tectonics, Rodinia, Paleozoic Inliers, Timeline Like other areas in the Grenville Province, the High Peaks region of New York is underlain by a large intrusive body of massif anorthosite, a rock composed of exceptionally large crystals of plagioclase feldspar.

Detailed explanation-2: -Superposition. Sedimentary rocks are deposited one on top of another. Therefore, the youngest layers are found at the top, and the oldest layers are found at the bottom of the sequence.

Detailed explanation-3: -Representatives from the modern family Monodontidae first appear in the fossil record 9 to 10 million years ago in the eastern north Pacific.

Detailed explanation-4: -It subdivides all time into named units of abstract time called-in descending order of duration-eons, eras, periods, epochs, and ages. The enumeration of those geologic time units is based on stratigraphy, which is the correlation and classification of rock strata.
