Jun 1, 2018 · Since cherts do not precipitate under high temperature conditions, hydrothermal events show a vertical change in diagenetic mineral assemblages. The amount of chert decreases with depth, which indicates that the prevailing temperature is increasing with depth (i.e., Chert α 1/depth; and Dolomite α depth; Fig. 3). Chert is a common sedimentary rock composed of microcrystalline quartz and impurities. It forms nodules, beds or veins in various geological settings and can contain fossils of radiolarians or other microorganisms.

In the Flint Hills section and in southeastern Kansas are gravels that consist mainly of just one mineral, chert or flint, which weathered from Paleozoic limestones. These brown, hard, resistant gravels commonly cap the uplands in Anderson, Cowley, Elk, Greenwood, Lyon, Morris, Wabaunsee, Geary, Riley, Pottawatomie, and Marshall counties.The climate of the source area can also influence composition. Most breccias are a mix of rock fragments and mineral grains. The type of rock that the fragments were produced from is often used as an adjective when referring to the rock. Some examples: sandstone breccia, limestone breccia, granite breccia, chert breccia, basalt breccia, and others.…
