When they die, their shells rain slowly down onto the ocean floor, creating an "ooze" which hardens into rock over millions of years. Chert is a type of sedimentary rock. It is a rock that contains silicon dioxide microcrystals in a high percentage and other trace elements and compounds like iron, organic matter, clay, and fossils.Mar 6, 2019 · Chert is a glass-like form of rock composed of tiny quartz (silicon oxide) crystals verging on a true glass where molten rock cooled so quickly as to be left with no crystal structure at all. Trace minerals mixed in with the silica give the various forms of chert their color. Common forms of chert include flint, jasper, agate, chalcedony, and onyx.
Rock Composition. Flint is composed of microscopic crystals of the mineral quartz (SiO2). Flint is quite similar to chert in many ways. The chert found in chalk was originally called flint.

Gray chert in tan limestone in Chase County. Commonly called flint, chert is a fine-grained, noncrystalline sedimentary rock made up of silicon dioxide (SiO 2 ).

Sedimentary rocks (layered rocks) are made by the deposition of particles carried in air or water and by the precipitation of chemicals dissolved in water. These particles and chemicals come from the weathering (breaking apart in place) and erosion (carrying away and breaking apart while moving) of rocks on the Earth’s surface.
