The carbonate massif of Mt. Peca consists of Ladinian-Carnian Wetterstein limestone and dolomite of backreef and reef development. The backreef limestone is bedded and with intrabiomicrite, ...intrabiopelmicrite and loferite textures. It was deposited in shallow and quiet sedimentation environment with short periodic emergences. The reef facies is characterized by corals, algae, spongians and other reefbuilding organisms. Te larger part of the Peca limestone is slightly dolomitized, and its reef part is in addition strongly recrystallized.With respect to fossil assemblage the reef limestone is attributed to Carnian, mainly to Cordevol.
In the year 2004, a deep borehole MET/04 east of Metlika in Bela Krajina was drilled. It reached the depth of 841 meters. The aim of drilling was to catch thermal water that would be used for ...touristical purposes. The area where the borehole is located belongsto the transitional zone of the External to the Internal Dinarides. The first ones are characterized mainly by shallow water carbonate rocks of Mesozoic age, while the other ones are composed mainly of deep water clastic rocks also of Mesozoic age. Structurally,this zone consists of a series of the Dinaric, NW-SE oriented, thrusts along which the Internal Dinarides are thrusted over the External ones. The bore hole itself is located in the flysch sequence of Upper Cretaceous age that is deposed transgressivelly onto theUpper Jurassic limestone. The flysch, that is composed of conglomerate, breccia, calcarenite and marl, is drilled to 182,5 m of depth. Further, to the 275 of depth, there follow Lower Cretaceous limestones, that belong either to large olistolitic blocks in the base of the flysch series or to a tectonic block of the imbricated structure. To the bottom of the borehole, there follow mainly ref and perireefal limestones of Upper Jurassic age. The upper part of these is determined to be of Upper Malmian age, since the lower part couldbelong to Lower Malmian. In the borehole, two water bearing zones were determined. The first one is in the interval from 92,5 to 184, and the second one in the interval from 220 to 355 meters at the depth.
Potočka zijalka was a station of Aurignatien hunters and the site of rich fossil remains of Pleistocene large mammals. Clastic sediments were deposited in Würm and are an intimate mixture of gravel, ...sand, silt and clay occurring in various proportions. Thefractions form distinct populations, which were transported by different agents, like rockfall, flowing water, ephemeral torrent flows and cryoturbation. The sediment constituents are petrologically rather diverse and indicate that they were derived from different parent rocks - Mesozoic limestone, Permian-Carboniferous shales, Tertiary fine-grained sediments and fluvial pebbly deposits.Bulk chemical composition is strongly influenced by the limestone component, but the majority of trace elements, like Ti, Li, V, Fe, Co, Zn, Ga, Y, REE, Zr, Nb, Cs, Hf and Th originates from clay and fine silt, and Mn, Pb, Ni, Cu and Sn mainly from the heavyminerals in the sand fraction. Ca, Mg, Br, Rb, Sr and U show strong correlation with the amount of carbonate component. Rare earth elements, normalised to PAAS are not appreciable fractionated and show light positive europium anomalies.
