Chert and flint are finely crystallized varieties of gray to black quartz that occur as nodules or bands in sedimentary rocks.

Chert is a sedimentary rock composed mostly of the mineral chalcedony—cryptocrystalline silica in crystals of submicroscopic size. This type of sedimentary rock can form in parts of the deep sea where the tiny shells of siliceous organisms are concentrated, or elsewhere where underground fluids replace sediments with silica.Clastic rocks. Clastic rocks are formed from the accumulation of pre-existing rock fragments or plant material in the case of lignite. Clastic sedimentary rocks are formed by mechanical processes such as erosion from a land mass. This erosion breaks the rock into fragments, which in turn are transported by either wind or water and redeposited. ….
