Serpentine is the name for a grouping of several related minerals, with the primary members being antigorite and chrysotile. Antigorite serpentine is typically representative of the solid forms of serpentine, of which these forms are typically columnar in structure. Chrysotile serpentine consists of four separate groups which are clinochrysotile, lizardite, orthochrysotile and parachrysotile, all of which have the same chemical composition. The difference between these groups of chrysotile serpentines are their crystal lattice's. There are a variety of other forms of serpentine, however most of them are extremely rare.
