Iberian Pyrite Belt

The Iberian Pyrite Belt is a vast geographical area with particular geological features that stretches along much of the south of the Iberian Peninsula, from Portugal to Spain. It is about 250 km long and 30–50 km wide, running northwest to southeast from Alcácer do Sal (Portugal) to Sevilla (Spain).^[1] The mining activity in this region goes back thousands of years.

The Iberian Pyrite Belt has had more than 2000 million tons of ore removed, and still has more than 400 million left to exploit. It is the largest concentration of massive sulfides in the world.
