WebChert - a variety of cryptocrystalline (no crystal structure) silica; formed by the precipitation of silica from solution. Flint: a variety of chert which is dark owing to the presence of carbon-rich material. Evaporites - chemical sedimentary rocks that form through the evaporation of water; usually found in dry lake beds (playas).
