Cassiterite Mineral Collection - Height: 2.8 cm - Width: 3 cm- 35 g - (1)

The main sources of cassiterite are often linked to hydrothermal veins, notably in areas such as Bolivia. These veins, formed by high-temperature fluids associated with granitic intrusions, create environments rich in minerals such as tourmaline and wolframite. Secondary deposits, found in alluvial or placer contexts in regions such as Malaysia and Indonesia, concentrate the durable grains of this mineral through weathering and erosion. The high specific gravity of cassiterite facilitates its concentration via hydraulic mining, making it economically viable. Igneous rocks can also host this mineral as a minor constituent.
