Chrysocolla is a hydroxylated copper silicate mineral that forms in the alteration zone around the edges of copper ore bodies. It is possible to make a search with precise filters (color, hardness, density, luster, shape, streak, magnetic or radioactive effects). Silicate - Silicates are the minerals containing silicon and oxygen in tetrahedral SiO44- units, which are linked together in several patterns. Two adjacent tetrahedra may share a vertex, meaning that the oxygen atom is a bridge connecting the two silicon atoms. Contrast a silicate mineral to a non-silicate (carbonate or organic) mineral in terms of composition, structure, and how it forms. Both are usually colorless, with a glassy luster. There is a single covalent link between the core silicon atom and each oxygen atom, giving each oxygen atom a negative one charge.
