Description
Summary:The hercynian outcrops of the Catalonian Coastal Ranges (NE Spain) consist mainly of Lower Permian-Upper Carboniferous, post-tectonic, epizona1 granitoid intrusions which form a typical applutonic calc-alkaline suite ranging from mafic hornblende gabbros and ultramafic olivine homblendites throught on alites and granodioritcs to leucogranites. This suite displays major andtrace-element characteristics and Sr isotope ratios similar to volcanic arc and post-collision magmatism oceanic lithosphere and to have been modified by contamination and is therefore believed to have formed above subducted with melts from the crust
