About Titanita
Titanite is a calcium–titanium nesosilicate, known for its flat, sharp crystals, often leaf-like. Beyond its aesthetic value, it can act as a small geological clock, allowing episodes of crystallisation, metamorphism or fluid circulation to be dated through the uranium–lead system.
About the locality
