Chlorite group and Antigorite Physical Properties

Chlorite group and Antigorite Chemical Formula

While comparing Chlorite group and Antigorite 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 Chlorite group and Antigorite chemical formula.

• Chemical formula of Chlorite group- (Mg,Fe)3(Si,Al)4O10(OH)2·(Mg,Fe)3(OH)6
• Chemical formula of Antigorite- (Mg,Fe2+ ) 3Si 2O 5(OH) 4Anthony et al , Handbook of mineralogy (2001)

Chlorite group and Antigorite Specific Gravity

Another important criteria for qualitative analysis of gemstones is Chlorite group and Antigorite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Chlorite group and Antigorite Optical Properties during the identification of gemstone. Specific gravity of Chlorite group is 2.58-2.80 whereas that of Antigorite is 2.58-2.80.
