Shale limestone sandstone

The Bright Angel Shale consists of locally fossiliferous, green and red-brown, micaceous, fissile shale (mudstone) and siltstone with local, thicker beds of brown to tan sandstone and limestone. It ranges in thickness from 57 to 450 feet (17 to 137 m). Typically, its thin-bedded shales and sandstones are interbedded in cm-scale cycles.

Shale limestone sandstone. Shale with interbedded sandstone and minor limestone characterize the Lower Triassic Candelaria Formation (Ferguson, Muller, and Cathcart, 1954). This vertically coarsening sequence grades up into a distal volcanogenic turbidite in the middle and a proximal turbidite and breccia near the top (Stewart, 1980).

Unlike limestone, sandstone is formed from rocks and minerals from the continental crust, rather than from minerals in the water of the ocean. One of the sandstones at Mammoth Cave, named the Big Clifty Sandstone, formed about 320 million years ago, when sand was deposited over top of Mammoth Cave’s shale and limestone beds by a large river ...
