Heavy minerals have been studied in order to address the problem of provenance and source area for the uppermost Oligocene to Early Miocene Krosno Formation in the Skole Nappe (Poland). The heavy mineral composition of the Krosno Formation in the Skole Nappe points to a metamorphic origin, mainly from pelites affected by amphibolite facies conditions. The Krosno Formation was deposited at least partly...
The Futoma Member (Oligocene, Rupelian) of the Menilite Formation is present only in the northern part of the Skole Nappe. Some diatomitic layers of this member in the Nowy Borek section contain coarse-grained detrital material composed of a variety of metamorphic, volcanic and sedimentary rock fragments. The material derives from primary and secondary sources. Most abundant are debris of metamorphic...
