WebChert is a microcrystalline or cryptocrystalline sedimentary rock material composed of silicon dioxide (SiO 2 ). It occurs as nodules and concretionary masses, and less frequently as a layered deposit. It breaks with a conchoidal fracture, often producing very sharp edges. WebNov 6, 2024 · Chalk beds, the calcareous equivalent of diatomites, may grow lumpy nodules of chert of the type called flint. Flint is commonly dark and gray, and more lustrous than typical chert.
