Abstract

This paper deals with the reverse (south-vergent) structures observed in the western part of the Krivánska Fatra Mts., developed during the Cenozoic evolution of the Western Carpathians. Geological setting of the Krivánska Fatra Mts. is interpreted on the basis of geological mapping and observation of mesoscopic and map-scale structures. Pre-Cenozoic nappe structure (from the bottom to the top: Tatric, Fatric, and Hronic units) of the study area was intensively affected and overprinted by a younger tectonic phase, which led to the formation of the present geological setting. Geological structure is typical by the NE–SW oriented structures with the top to the S–SE tectonic displacement. The age of this tectonic event – south-vergent backthrusting is considered to be the Early Miocene because affected also the sediments of the Central Carpathian Palaeogene Basin.


Key words: geological mapping, backthrusting, Cenozoic evolution, Krivánska Fatra Mts., Central Western Carpathians
