Staurolite and Tremolite Chemical Formula
While comparing Staurolite and Tremolite 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 Staurolite and Tremolite chemical formula.
- Chemical formula of Staurolite- (Fe,Mg,Zn) 2Al 9(Si,Al) 4O 22(OH) 2Ulrich Henn and Claudio C.
- Chemical formula of Tremolite- Ca 2Mg 5Si 8O 22(OH) 2Ulrich Henn and Claudio C.
Staurolite and Tremolite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Staurolite and Tremolite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Staurolite and Tremolite Optical Properties during the identification of gemstone. Specific gravity of Staurolite is 2.95-3.07 whereas that of Tremolite is 2.95-3.07.
