Abstract
Investigated area of the Cave Park Grabovača, near Perušić town in the Lika region, Croatia, is composed predominatly of Cretaceous carbonate rocks – limestones, dolomites and dolomte breccia, as well as of Paleogene-Neogene calcareous breccia. According to their facies characteristics the rocks are separated and described in following stratigraphic units: the Lower Aptian palorbitolina and bacinella limestones, the Upper Aptian emerged breccia and limestones, the Lower Albian emerged breccia, the Upper Albian limestones, transitional Upper Albian to the Lower Cenomanian dolomites and dolomite breccia, the Upper Cretaceous limestones, the Paleogene-Neogene calcareous breccia and the Holocene deposits. With regard to tectonic structures this terrain is composed of several anticlines and syclines of the Dinaric orientation i.e. with northwest to southeast striking. After folding during the Neogene those structures were disturbed by several reversed and numerous normal faults.
