Geological Formation of Topaz
Topaz is a silicate mineral that forms mainly in felsic igneous rocks. It comes from specific geological processes. The formation of topaz happens in magmatic, hydrothermal, and metamorphic environments. These settings let topaz crystallize from molten rock, often in pegmatitic areas with large crystals.
This process leads to the wide variety of topaz found around the world. The unique way it forms makes topaz interesting to study.
Topaz has an orthorhombic structure and can be easily split along certain planes. It's hard, with a Mohs hardness of 8, showing it's very durable. Its specific gravity is between 3.4 and 3.6, showing it's dense.
