System:MonoclinicColour:black-green, dark green
Lustre:VitreousHardness:5 - 6
Member of:Tremolite-actinolite series Group > Calcium Amphibole Subgroup > w(OH, F, Cl)-dominant Amphibole Group > Amphibole Supergroup
Name:Named in 1946 by Nils Sundius for its relationship to Actinolite.


Note: Tremolite is defined as having an Mg/(Mg+Fe2+) ratio ≥ 0.9; Actinolite has a ratio of 0.5–0.9 and Ferro-Actinolite has a ratio of less than 0.5.
