CLASTIC ADMIXTURE IN DOGGER CRINOIDAL LIMESTONES OF CZORSZTYN UNIT
Year, pages: 1993, 105 - 111
The clastic admixture in the Smolegowa and Krupianka Limestones (Czorsztyn Unit) was analysed in various localities. Heavy mineral analysis shows the predominance of garnet and zircon and smaller quantities of rutile, tourmaline and other minerals. By the method of zircon typology three various granitoid sources were distinguished, two of them unknown in the Hercynian granitoids of the Central Western Carpathians. The reconstruction of the source area shows a similarity with the core mountains of the Central Western Carpathians with granitoids intruded into a metamorphosed complex and covered with sedimentary rocks, but with differences in the chemical composition of the granitoids. This fact supports the theory about the separation of the sedimentation area of the Pieninic units from the Central Western Carpathians during Dogger.
