ABSTRACT
After Neogene, Cretaceous covers the most part of the surface of Rahovec Region. It includes part of the Internal Dinarides and External parts of the Vardar zone. Cretaceous formation has a wider spread with diverse representation facies formed in different bathymetric environmental settings. Based on the presence of members of the Cretaceous, their unequal position in relation to older depositions and their different facial characteristics we have separated the two tectonic-stratigraphic belts of the Cretaceous deposits developments in the study area. Stratigraphy of Cretaceous deposits consists from: 1. Cretaceous carbonates of western belt (bauxite bearing): Spreading around of mountains Gremnik-Llapçeva -Shkoza-Pagarushë and Zatriq country. The Cretaceous period in this area is presented in two series: The Lower/Early Cretaceous and the Upper/Later Cretaceous. By the point of facial view, depositions of the Cretaceous series consist of: carbonate sediments of shallow waters, reef, Sub-reef sediments (Carbonate Turbidity), littoral and pelagic limestone. The higher spreads have the deposits of the Upper/Later Cretaceous than the Lower/Early Cretaceous: Based on the studies of the biostratigraphy and the features of the lithofacies of some outcrops of selected cross sections we have distinguished these divisions of facial disposal. 2. Cretaceous carbonate-clastic of the eastern belt (non-bauxite bearing): Are spread widely from Pograde in the North, towards Southeast in Panorc village, finishing in Rahovec city. The Sferka transfers tectonic detachment separates Eastern Belt in the two sectors: southern sector, where they meet the older facies of the Lower Cretaceous Barrem-Apt and Alb - Senomanian and Turonian-Senonian facies of the Upper Cretaceous. (Lonqareviq 1978, [4] Elezaj, Kodra 2008) [1] Noted the presence of the break among the turon neritic limestone and pelagic sediments of the senonian /marly/. In the North and East sector, there were missing the Lower Cretaceous facies and it is noticed the transgressive placement of the senonian pelagic limestone directly above the ultrabasic rocks.
