Description
The name of the mineral scolecite is derived from the Ancient Greek σκώληξ (skōlēx), meaning "worm." This is because of the mineral's reaction when held near a flame. Scolecite is a mineral formed by low-temperature weathering of basalts and related rocks. The type locality is Kaiserstuhl, Baden, Germany. It is also found in the Nashik district of the Indian state of Maharashtra. The transparent to translucent colorless, white or brown scolecite has a vitreous to satiny luster, a white streak color, and perfect cleavage along the crystal plane [110]. The average density is 2.28 and the hardness is 5 to 5.5. The crystal system is monoclinic, and the mineral is not radioactive. The mineral scolecite is a hydrated calcium-aluminum silicate with the chemical formula CaAl2Si3O10·3(H2O). This tecto-silicate belongs to the zeolites.
