Chert is a rock containing high amounts of silica that formed from sediment composed of shells of microorganisms called …Chert. Chert is a sedimentary rock consisting almost entirely of silica (SiO 2 ), and can form in a variety of ways. Biochemical chert is formed when the siliceous skeletons of marine plankton are dissolved during diagenesis, with silica being precipitated from the resulting solution. Replacement chert forms when other material is replaced by ...The residual chert overlies cherty dolomites that grade downwards into cherty dolomitic limestones, cherty limestones, and limestones at the base. These compositional changes can also be seen reflected on gamma-ray, photoelectric factor, neutron and density porosity curve overlays.

Known to mineral collectors as “rice agate,” these polished stones of black chert (flint) consist of a dense variety of silica found in the sedimentary rocks of Montgomery County. The “rice” pattern comes from numerous white shells of fossil fusulinids, a tiny marine protozoan.Quartz is a hard, crystalline mineral composed of silica (silicon dioxide).The atoms are linked in a continuous framework of SiO 4 silicon–oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO 2.Quartz is the second most abundant mineral in Earth's continental crust, behind feldspar..

Chert (the silica mineral kind) may be massive or layered. It is often in nodules or concretions in limestone. Some chert forms by recrystallization of amorphous silica. Chert has many appearances; the five photos below (Figures 7.59 to 7.63) show examples of some of the more common varieties. Common chert is light grey.

Mineral Deposits: Breccia can serve as a host rock for mineral deposits.
