The features of the Iberian Pyrite Belt (extending through the provinces of Huelva, Seville, Algarve and Alentejo), have led to its exploitation since before the Roman Empire. The increasing price of metals and the growing global mineral demand during the last decade makes the Iberian Pyrite Belt a place of a great interest in mining.

Abstract [1] The South Portuguese Zone (SPZ) constitutes the southernmost segment of the Variscan Iberian Massif. It is bounded to the north by the BejaAcebuches Ophiolitic Complex and related accretionary wedge. To the south lie the Iberian Pyrite Belt (IPB) and flysch deposits forming the southern extent of the zone.
Apr 17, 2013· The Iberian Pyrite Belt (IPB) corresponds to an area of DevonianCarboniferous Superior (380 to 290 million years) volcanic and sedimentary rocks containing massive polymetallic sulfide deposits. This area forms a belt, about 250 km long and up to 60 km wide, trending westwards from near Seville in Spain to westnorthwest in South Portugal. ...
The Iberian Pyrite Belt, located in the southwest of the Iberian Peninsula (Fig. 1), with an estimated preerosional billion tons of sulfides, is the largest (in tonnage) VHMS province in the world (Carvalho et al., 1999). It is 250 km long and 30 to 60 km wide. The stratigraphic sequence in the belt
The Iberian Pyrite Belt (IPB) hosts one of the world's largest accumulations of acidic mine wastes and pit lakes. The mineralogical and textural characteristics of the IPB ores have favored the oxidation and dissolution of metallic sulfides, mainly pyrite, and the subsequent formation of acidic mining drainages.

The Iberian Pyrite Belt (IPB) in so uthwestern Spain hosts one of the largest sulphide deposits in the world, as well as the Río Tinto Mars analog (8–10). In previous work, we characterized pyriterich drill core samples down to 166m d epth with several molecular ecology techniques, and revealed a subsurface ecosystem with active
The granite is associated with a series of ore showings (FPbZn and SnW) which are completely different from the nearby, massive sulphide and manganese ore deposits of the Iberian Pyrite Belt, indicating the unique character of this intrusion.

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).
1990). About 5Mt of pyrite had been mined from the Rio Tinto by the time Carthage fell at the end of the Third Punic War in 146 (Pinedo, 1963). Spain became a Roman province, and mining of the rich deposits of the Iberian pyrite belt for copper and silver started on a larger scale. Stillvisible slag deposits indicate that about
