It occurs as nodules, concretionary masses, and …Limestone is a sedimentary rock composed primarily of calcite, a calcium carbonate mineral with a chemical composition of CaCO 3. It usually forms in clear, calm, warm, shallow marine waters. Limestone is usually a biological sedimentary rock, forming from the accumulation of shell, coral, algal, fecal, and other organic debris.chert and flint, very fine-grained quartz ( q.v. ), a silica mineral with minor impurities. Several varieties are included under the general term chert: jasper, chalcedony, agate ( qq.v. ), flint, porcelanite, and novaculite. Flint is gray to black and nearly opaque (translucent brown in thin splinters) because of included carbonaceous matter.
