The Jablonové Deposit

The reserved Jablonové deposit is located in the Bytča District of the Žilina Region, cca. 200 m southeast of the village of Jablonové, close to the state road to Súľovo. The deposit is developed as an open quarry with 7 benches on the northern edge of a sharp ridge formed primarily of Palaeogeneous conglomerates and sandstone and stretching in a SSW-NNE direction, with its highest points being Havrania Skala (835 m asl.) and Stupovec (806 m asl.). The quarry is located on a steep northeastern slope above the deep valley of the Hradnianka River. The terrain’s elevation ranges between 337 and 481 m asl.

The deposit constitutes a part of the Inner Carpathian Paleogene zone of the Žilina-Rajec Basin. The rocks that are exploited are sandy limestone, calcareous sandstones and conglomerates of the Palaeogene of the klippen zone. The predominant type of rock is limestone, alternating with calcareous sandstones and with the lenticular positions of coarse conglomerates (i.e. the Paštinsko-závadské layers). The conglomerates and the breccias of Paštinsko-závadské layers are either massive or poorly stratified and consisting almost entirely of fragments of carboniferous rocks (e.g. limestone, dolomite and marly limestone). The overburden (in the western part of the deposit) is comprised of blue-grey and grey limestone banks of the Jablonovské formation with an abundance of quartz and carbonate detritic material. The layers of carboniferous rocks run in a SSW - NNE direction with the inclination of 45-80° towards the WNW. The rocks on the deposit are penetrated by several systems of fissures that are associated with post-Paleogeneous tectonics. The most distinctive of these are the large discontinuity planes with a faulting polish in the NW-SE direction with a steep inclination towards the N-NE. All the petrographic types together constitute a single deposit body with a base level of 338 m asl. and a very rugged terrain surface. The thickness of the deposit body is in the range of between 0 and 145 m.
