Mineral identification is based on the testing of the physical properties and morphology of crystals. There are over 5,600 minerals that have been discovered on Earth so far! Additionally, you can use identification resources like books and flow charts. How do you identify a silicate mineral? A silicate mineral is generally an ionic compound whose anions consist predominantly of silicon and oxygen atoms. In the following table record the physical properties of each unknown, and use the mineral identification tables to identify the specimens. Chrysocolla is a hydroxylated copper silicate mineral that forms in the alteration zone around the edges of copper ore bodies. Silicate - Silicates are the minerals containing silicon and oxygen in tetrahedral SiO44- units, which are linked together in several patterns. This group is based on the silica (SiO4) tetrahedron structure, in which a silicon atom is covalently bonded to 4 oxygen atoms at the corners of a triangular pyramid shape.
