Serpentine is a major rock forming mineral and is found as a constituent in many metamorphic and weather igneous rocks. It often colors many of these rocks to a green color and most rocks that have a green color probably have serpentine in some amount. Serpentine is actually a general name applied to several members of a polymorphic group. These minerals have essentially the same chemistry but different structures. The following is a list of these minerals, their formulas and symmetry class:
Antigorite; (Mg,Fe)3Si2O5(OH)4; monoclinic.
Clinochrysotile; Mg3Si2O5(OH)4; monoclinic.
Lizardite; Mg3Si2O5(OH)4; trigonal and hexagonal.
Orthochrysotile; Mg3Si2O5(OH)4; orthorhombic.
Parachrysotile; (Mg,Fe)3Si2O5(OH)4; orthorhombic.
Mg6Cr2CO3(OH)16 · 4H2O
Stichtite is a rare and unusual carbonate. It forms mostly in compact masses or micaceous aggregates, in contrast to the majority of carbonates that form well shaped, large and abundant crystals. Its most common locality is near Dundas on the Island of Tasmania and in fact almost all specimens sold in rock shops and from mineral dealers have Dundas listed as the source. Stichtite has a some what dull purple pink to purple rose red colour. Serpentine is usually associated with stichtite. This green and purple pink combination can make for an attractive specimen or ornamental stone carving and Jewellery.
