Hercynian granites and metamorphic rocks from the Mts. Papuk, Psunj, Krndija, and the Surroundi ng basement of the Pannonian Basin in Slavonija (Northern Croatia, Yugoslavia)

Abstract

Hercynian crystalline complex of the Slavonian Mountains and surrounding basement of the Pannonian Basin comprises the following units: (1) anchimetamorphic and very low-grade metamorphic rocks with metabasic igneous rocks, (2)progressive metamorphic succession of greenschist and amphibolite facies, (3),migmatites, (4) S-type granitoids, and (5) I-type granitoids.In the paper is presented a petrological interpretation for each of the mentioned unit which is based on chemical composition of rock-forming minerals,petrographical and geochemical data including major and trace element contents,REE, and O and Sr isotopie composition.Numerous geochemical and petrochemical diagrams are presented for allthese rock groups as the basis for detailed genetic and geotectonic considerations.
