Geophysical evidence of a mantle derived intrusion in SW Iberia -: art. no. L11601

[ 1] Deep seismic reflection data acquired as part of SW-Iberia EUROPROBE project across the Variscan orogen sample three tectonic terranes: the Portuguese Zone, the Ossa-Morena Zone, and the Iberian Zone. The seismic data reveal the existence of mid-crustal reflective body 140 km long and of thickness ( up to 5 km), the Iberian Reflective The conductivity image provided by coincident soundings, the amplitude characteristics of the mineralization studies related to magmatic ore deposits, the surface geology suggest that the IRB is a mantle-mafic intrusion. The geophysical, geological petrological data suggest that the IRB is most probably Early Carboniferous ( approximately at 350-340 mantle-derived intrusion possibly linked to plume that took place in Europe in the Carboniferous Permian.
