Abstract

The geology of Mt. Nosal (Western Tatra Mts.)Among the crags of Mt. Nasal which belongs to the sub-tatric range of the vicinity of Zakopane (Western Tatras), we can observe a well preserved synclinal twist, closed from the south, already reported by Z. Kotański (1959b, 1963). This twist formed in the Anisian limestones and dolomites of the Mała Świnica unit which had been overthrust onto the Keuper, Rhaetic -and Liassic rocks of the Suchy Wierch unit owing to the stress from the south (comp. Guzik & Kotański 1963). The presence of this twist indicates the scale-nappe style in the geology of the Tatra Mts. (Kotański 1961, Guzik & Kotański op. cit.), and not the digitation-nappe style, which was accepted previously (Goetel & Sokołowski 1930). The synclinal twist of Mt. Nosal is cut up by many transverse dislocations formed owing to the subsidence of the rigid Middle-Triassic rocks on the more plastic sediments of the Upper Triassic and Liassic (comp. Goetel & Sokołowski op. cit.). Some of these faults came into existence immediately after the formation of the synclinal twist of Mt. Nosal, others are post-Eocene in age as is reliably indicated by the fact that deposits of the transgreding Eocene are dissected by these faults.
