Geochemistry and petrology of some granitoids from Papuk and Psunj Slavonian Mountains (Croatia)

The investigated granitoids of Papuk and Psunj-Krndija Complexes in Slavonia (Croatia) are quartz diorite, granodiorite and monzogranite. Intermediate to highly ordered microcline suggests a slow rate of cooling. The composition of plagioclase is andezine in the quartz diorite and oligoclase in the granodiorite and monzogranite. The granitoids contain primary muscovite and biotite showing peraluminous character in Papuk Complex, whereas the amphibole and lack of muscovite in granitoids of Psunj-Krndija Complex indicating a transitional met- and peraluminous characters.
