Minerals — Titanite

Titanite, also known as sphene, is a calcium titanium nesosilicate mineral with the chemical formula CaTiSiO5. It typically occurs in metamorphic and igneous rocks, particularly those of granitic and syenitic composition. Titanite is a relatively rare mineral, but it can be found in a variety of localities around the world.The crystal structure of Titanite consists of a framework of SiO4 tetrahedra, with additional titanium cations and calcium cations occupying specific sites within the framework. This gives Titanite its characteristic brown, yellow, or green coloration, which can sometimes be quite vivid.One of the most interesting properties of Titanite is its strong...
