Abstract
The Triassic magmatism of the Dinarides had a polyphase character. It took place during a period of about 50 Ma during the initial stages of the Mesozoic Wilson cycle. Their earliest phases might have been connected with rifting processes, and the subsequent ones preceeded directly the opening of the Dinaridic part of the Tethys and the formation of a spreading ridge. The Triassic magmatism is represented by basic, and more commonly by intermediate and acid plutonic and volcanic rocks with calc-alkaline affinity. The Triassic magmatic rock association can be correlated on major element evidence with calc-alkaline rocks of recent convergent plate margins. However, field relationships and the data on immobile trace elements indicate that lavas poured out over Triassic sediments on a carbonate platform which was underlain by rocks of the continental crust. The basic diversity of the Triassic magmatism of the Dinarides was influenced by partial melting. Other processes (crystallization, contamination and others) must have played a secondary role.
