System:MonoclinicColour:White, brown, ...
Lustre:Vitreous, SilkyHardness:5 - 6
Member of:Tremolite-actinolite group > Calcium Amphibole Subgroup > w(OH, F, Cl)-dominant Amphibole Group > Amphibole Supergroup
Name:Named in 1789 by Johann Georg Albrecht Höpfner for the Tremola Valley (Val Tremola), Central St Gotthard Massif, Tessin, Switzerland, where the type material supposedly came from, according to the dealer from whom he had acquired the specimens. However, modern investigations of what is considered the type material, conserved at Geneva, revealed that the true type locality is Campolungo, Tessin. (Val Tremola which lies north of the isograd delineating the first appearance of tremolite). This mineral was earlier (1782) called Säulenspath and Sternspath by Johann Ehrenreich von Fichtel for material from Sebeşu de Jos, Transsylvania, Romania.
