Antigorite and Zoisite Chemical Formula
While comparing Antigorite and Zoisite physical properties, the important data you should know is its chemical composition. Since chemical formula defines the molecular structure of the crystal, most of the physical properties like color, tenacity, solubility are governed by Antigorite and Zoisite chemical formula.
- Chemical formula of Antigorite- (Mg,Fe2+ ) 3Si 2O 5(OH) 4Anthony et al , Handbook of mineralogy (2001)
- Chemical formula of Zoisite- Ca2Al3(SiO4)3(OH)
Antigorite and Zoisite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Antigorite and Zoisite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Antigorite and Zoisite Optical Properties during the identification of gemstone. Specific gravity of Antigorite is 3.20-3.50 whereas that of Zoisite is 3.20-3.50.
