O charakterze mezozoicznej geosynkliny Karpat Zachodnich i o epimiogeosynklinie podhalańskiej

Abstract

On the character of the Western Carpathian Mesozoic geosyncline and the Podhale epimiogeosynclineEvidence is given of the miogeosynclinal character of the geosyncline in the Mesozoic of the Western Carpathians. This is most conclusively demonstrated - in agreement with M. Kay's (1947, 1951) statement - by the lack of well developed initial volcanism. Neither the Lower Triassic volcanites of Chocz, the Tithonian high-tatric limburgites, nor the Lower Cretaceous teschenites from the Flysch of the Outer Carpathians, may be regarded as expressions of this volcanism. Spilites from the exotics of the Pieniny Clippen Belt most likely do not derive from the Mesozoic but from the Paleozoic. Hence, contrary to what D. Andrusov (1958, 1959) postulated, there is no reasonable ground to suppose that during the Mesozoic eugeosynclinal and miogeosynclinal basins occurred alternately within the Western Carpathians. On the other hand, within the miogeosyncline, the alternate occurrence may be observed of intrageanticlinal basins (e.g. the high-tatric and the Czorsztyn series) and of intrageosynclinal basins (e.g. the sub-tatric and the Pieniny series). With reference to M. Kay's classification of geosynclines, a new type - the epimiogeosyncline, has been erected by the writer. This is a secondary geosyncline (epigeosyncline) which after the tectogenesis of the Alpine type replaced the miogeosyncline. The epimiogeosynclinal sediments display a deep-sea mainly Flysch, character. The Podhale Flysch in the CentraI (Inner) Carpathians are the representative type of this kind of sediments.
