Abstract
According to the geological relationships in the region of Pozeska gora Mt. (the southern margin of the Pannonian Basin, northern Croatia), basic eruptive rocks are considered to be of Upper Cretaceous-Palaeogene age. Detailed petrographic examination, based on physiographic description, the chemical composition of major and trace elements, rare earth elements and stable isotopes, indicates that these primary tholeiitic basalts have variable structural-textural characteristics, and were postmagmatically affected by metamorphic processes. Tholeiitic basalts originated from the upper mantle, and were placed in the form of subaquatic effusions in the extensional zones within continental crust.
