Petrology and Geochemistry of Mafic-Ultramafic Fragments from the Aguablanca Ni-Cu Ore Breccia, Southwest Spain

“…7A, B): strong enrichment in LILE and Pb, slight enrichment in LREE with respect to HREE, and depletion of Nb and Ta (Perfit et al, 1980). The geodynamic context of the Aguablanca ore deposit, therefore, contrasts with most other Ni-Cu deposits that are closely related to rift settings (Lesher, 1997) and only rarely occur in compressive orogenic environments (e.g., the Moxie pluton: Thompson and Naldrett, 1984; the Caledonian intrusions of northeast Scotland : Fletcher, 1987; the Rana intrusion: Boyd and Mathisen, 1979). Recent geophysical studies of the southwest Iberian Peninsula (seismic reflection profile, IBERSEIS: Simancas et al, 2003) have revealed the presence of a thick, sill-like structure represented by a long high-amplitude reflective band in a midcrustal decollement.…”
