Wenshi is a carbonate mineral. The component is CaCO3. Also known as aragonite, it is homogeneous and resembles calcite and other minerals. The rhombohedral system is characterized by columnar or lance shaped crystals, commonly exhibiting pseudo hexagonal symmetry in three connected crystals. Collectives are often in the form of shells, concretions, beans, spherical particles, etc. Usually white or yellow white in color. Glass gloss, with a grease gloss on the fracture surface. Incomplete cleavage of the board surface. Shell shaped fracture. Mohs hardness is 3.5-4.5. The specific gravity is between 2.9 and 3.0. In nature, aragonite is unstable and often transforms into calcite. Mainly formed under exogenous conditions, occurring in modern seabed sediments or clay; In limestone caves.
