Triassic magmatism in Dinarides and its products

Triassic rift related magmatism was dominantly of intermediate in character. It produced basalts, andesites and dacite at the extrusive level, and gabbro, diorite, granosyenite and granite in the intrusive levels and lasted at least 40 to 50 Ma. It is spatially and genetically related to the sedimentary formation of the Gondwana passive continental margin and later on totally covered by the Mesozoic carbonate platform formation. The spatial extension can be traced along the whole Alpine-Himalayan orogenic belt. Its equivalents in time, on the Euroasian diverging margin, which was subjected to long-term destructive, subduction related processes, during convergence, since the Jurassic to the Early Cretaceous, are not easily recognized. The intensity of the magmatism ceased with the opening of the Tethys, and accompanied ophiolite formation. Study of Triassic magmatism and its products, including ore deposits, is a key to palinspastic interpretation and geological evolution of the Tethys.
