Tremolite amphibole
WebTremolite is a calcium magnesium iron silicate in the amphibole group. It forms a series with actinolite and ferroactinolite, representing the magnesium-dominant end. Ferroactinolite is the iron-dominant end, while actinolite is in the middle. Web• The most common amphibole is hornblende (monoclinic) (Ca,Na) 2-3 (Mg,Fe +2,Fe +3,Al) 5 Si 6 (Si,Al) 2 O 22 (OH) 2. • Other common amphiboles belong to tremolite (Ca 2 Mg 5 Si 8 O 22 (OH) 2-actinolite (Ca 2 Fe 5 Si 8 O 22 (OH) 2) series with hardness on Mohs' scale of 5 to 6. • Fibrous species of amphiboles from the tremolite-actinolite ...
