Augite and Zoisite Chemical Formula
While comparing Augite 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 Augite and Zoisite chemical formula.
- Chemical formula of Augite- (Ca,Na)(Mg,Fe,Al,Ti)(Si,Al) 2O 6Anthony et al , Handbook of mineralogy (2001)
- Chemical formula of Zoisite- Ca2Al3(SiO4)3(OH)
Augite and Zoisite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Augite and Zoisite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Augite and Zoisite Optical Properties during the identification of gemstone. Specific gravity of Augite is 3.20-3.50 whereas that of Zoisite is 3.20-3.50.
