Flint (or flintstone) is a hard, sedimentary, cryptocrystalline form of the mineral quartz, categorized as a variety of chert. It occurs chiefly as nodules and masses in sedimentary rocks, such as chalks and limestones. Inside the nodule, flint is usually dark gray, black, green, white, or brown in color, and often has a glassy or waxy appearance.chert: [noun] a rock resembling flint and consisting essentially of a large amount of fibrous chalcedony with smaller amounts of cryptocrystalline quartz and amorphous silica.10 thg 10, 2022 ...

Trace minerals mixed in with the silica give the various forms of chert their color. Common forms of chert include flint, jasper, agate, chalcedony, and onyx. This chert is less desirable than flint for making bladed instruments or gemstones. Jasper: a type of chert that forms primary deposits. It is found inside or connected to magmatic formations. Radiolarite: a type of chert with radiolarian (unicellular protists) microfossils and forms as a primary deposit.
