Is chert a mineral or a rock
Chert is a sedimentary rock composed mostly of the mineral chalcedony—cryptocrystalline silica in crystals of submicroscopic size. This type of sedimentary rock can form in parts of the deep sea where the tiny shells of siliceous organisms are concentrated, or elsewhere where underground fluids replace sediments with silica.Rocks are generally placed into 1 of 3 major categories: igneous, metamorphic, or sedimentary. Igneous rocks have solidified from molten or partly molten mineral matter. Metamorphic rocks have been altered in the solid state from some pre-existing condition in response to significant changes in temperature, pressure, or chemical environment.For example, in West Virginia, a large pocket of natural gas occurs within such as the rock formation, known as the Huntersville Chert. Chert can take on various colors. Gray is common, as is white and pink. It can exhibit a solid color or contain bands of other minerals or fossils. People can confuse agate and chert because of the colors.
