Unfossiliferous conglomerate consisting of fragments of Triassic through Lower Cretaceous sedimentary rock pebbles derived from the Lower Subtatric Nappe, occurs in the Rusinowa Polana area, Polish Tatra Mts (Carpathians). Thus far, this conglomerate was considered to represent a basal unit of the Eocene transgression deposits post-dating the meso-Cretaceous nappes. New field survey shows, however, that it takes part in architecture of the pre-Eocene Lower Subtatric Nappe system. The conglomerate, formally distinguished as the Rusinowa Conglomerate Formation (new formation), is here correlated with the Upper Cretaceous Gosau Group, as known from the Northern Limestone Alps. A post-Gosau but pre-Eocene, Laramian phase of folding is postulated as a new and important stage of tectonism in the Tatra Mts. The Rusinowa Conglomerate Formation is, moreover, displaced by numerous SW-NE-trending faults of post-Oligocene (probably Sarmatian) age.
