Deskripsi

Coarse-grained clastic sediments of rhyolitic-granitic composition which are associated with the magmatic complex of Mt. Pozeska Gora were previously designated as granites. They are deposited in a continental environment or, more precisely, in an alluvial fan or proximal parts of a braided river system, or in rapid mountain streams during a strong rainfalls. According to their spatial relationship with respect to surrounding Upper Cretaceous granites and rhyolites and Ottnangian sediments; and considering the facies characteristics, we assume that these sediments belong to the Oligocene.
