The Iberian Pyrite Belt is a geological formation located in southwestern Europe, primarily in southern Spain and Portugal. It is known for its rich deposits of sulfide minerals, particularly pyrite, which is often referred to as "fool's gold." This belt is significant for its extensive mining history, particularly for copper, zinc, and lead. The region spans approximately 250 kilometers and features various mining sites that have been active since ancient times. The Iberian Pyrite Belt is also important for studying geological processes and the environmental impacts of mining activities. Its unique mineralogy attracts researchers and geologists interested in economic geology and mineral resources.
