Mineral: | Thorite
| Chemical Formula: | (Th,U)SiO4 | Size: | | Weight: | | Transparence: | | Quantity: | | Origin: | secondary deposit: Onh Bin Yee Htwet , Le-Oo (Le U), northeast of Mogok, primary source might be: Oh Saung Taung, Le-Oo (Le U) Burma (Myanmar) | This is a slightly rounded Thorite crystal disclosing a doubly terminated shape. The crystal seems to be weathered and shows some brownish secondary mineral which might be ferrithorite. The crystal emits 7,5 µSv/h gamma particle and include alpha- and beta- particles the total dose is 30µSv/h. A well sized specimen with still good prismatic shape!
