Tilleyite

Ca5Si2O7(CO3)2
Monoclinic root IMA grandfathered

Tilleyite is a calcium silicate carbonate mineral with the chemical formula calcium five silicon two oxygen seven carbonate two. It crystallizes in the monoclinic crystal system and belongs to the space group P2₁/a. In the Strunz classification, it is categorized as 9.BE.82, and in the Dana system as 56.2.9.1. Tilleyite typically exhibits a vitreous luster and is generally colorless or white in appearance. It has a hardness of approximately 4 to 4.5 on the Mohs scale and a relatively low density. This mineral is classified as a nesosilicate, a group of silicate minerals in which the silicate tetrahedra are isolated from one another.
