cassiterite
Primary tin source
Cassiterite is the principal ore of tin, a dark brown or black mineral found in igneous rocks and alluvial deposits.
It has been mined since ancient times—the word derives from the Greek name for the Tin Islands, likely referring to Cornwall or the coast of Spain.
The cassiterite deposits made the region a center of Bronze Age trade.
