The Iberian Pyrite Belt, which extends from Portugal to Spain in southwest Iberia, constitutes one of the world's largest reservoirs of massive sulphide deposits. Volcanic-hosted massive sulphide mineralization occurs at several stratigraphic horizons within an Early Carboniferous volcano-sedimentary package formed of turbiditic siliciclastic deposits and basaltic, intermediate and …

Geochemistry and mineralogy of AMD in the Iberian Pyrite Belt (Spain). These metal concentrations are among the highest of those reported for world-wide AMD of diverse deposit types (Fig. 2), and suggests significant pyrite oxidation and dissolution, as well as oxidative dissolution of other sulphides (chalcopirite, sphalerite, galena, arsenopyri-

1. Introduction. The Las Cruces orebody is located at the eastern corner of the Iberian Pyrite Belt (IPB), 25 km northwest of Seville (Spain), and it is covered by a detrital and carbonate sequence, 150-m-thick, of the Guadalquivir foreland Basin.. The Las Cruces deposit included a polymetallic massive sulfide orebody and a Cu-rich stockwork.

Summary The Iberian Pyrite Belt (IPB), located in Spain and Portugal, is one of the world's largest polymetallic massive sulphide complexes with predominantly Cu, Pb and Zn mineralisations. The mining potential is still existing, but as prospecting and exploration is becoming increasingly expensive, there is a need for efficient and application-oriented methods to identify potential …

The Iberian Pyrite Belt (IPB) is an outstanding VMS district located in the SW of the Iberian Peninsula (Fig. 2). It is arguably the largest known accumulation of sulfides on the Earth's crust ( > 1.6 Bt; Tornos, 2006) and represents the main mining area in Spain and one of the main zones of base metal production in Europe.

The Iberian Pyrite Belt is located in the Southwest of the Iberian Peninsula, and comprises a large part of the Setubal and Beja districts in Portugal, and Huelva and Seville provinces in Spain (Figure 2). The region is an eroded peneplain, plunging gently to the. Read more Read less

The Iberian Pyrite Belt is one of the three areas of the South Portuguese Zone, the southernmost terrane of the Variscan Belt of Iberia ().It is characterized by the presence of a relatively simple geological record (Schermerhorn, 1971; Fig. 2), with a sequence that includes about 1000 to 5000 m of Late Paleozoic rocks.The oldest rocks found are grouped in the PQ …

In the Iberian Pyrite Belt, this is the beginning of the south directed thin-skinned tectonics (D 1) coeval the synorogenic Culm deposits setting. During the upper Visean the collision reached its climax, as recorded in the Iberian Pyrite Belt by the D 2 - and D 3 -related structures ( Figures 5 and 10e ).

The Iberian Pyrite Belt is one of the four Variscan structural units distinguished by Quesada, (1991) in the South Portuguese Zone (Figs 1 and 2). It is bounded to the north by the Pulo do Lobo oceanic terrane and to the south by the Baixo Alentejo Flysch Group. The main feature of the Iberian Pyrite Belt is the occurrence of polymetallic ...

The Iberian Pyrite Belt (IPB) has been one of the major mining districts in Europe since prehistoric times [8,9]. It is an area of significant geological and metallogenic interest because it represents the largest concentration of metallic sulfide deposits on Earth [10–12]. With more than 2000 Mt of massive

Mining activity in Algares (Aljustrel Mine, Portuguese sector of the Iberian Pyrite Belt, IPB) stems prior to Roman times. As the orebody is vertical and relatively thin, mining was carried out mainly along underground adits (galleries). Nowadays, the deposit is considered exhausted and the area is being rehabilitated for a different use. The Algares +30 level adit intersects two …

The Iberian Pyrite Belt (in southwest Spain and Portugal) is a wide outcrop which hosts massive sulfide deposits, and is responsible for significant acid mine drainage (Figure 1), making it a favorable geological test case for hyperspectral image analysis. Pyrite mining has been conducted on the Iberian
