Comparision of the Outer and Inner Dinaride’s caves: the case of Vrdovo (Dinara Mt.) and Žumberak Mts., Croatia

Caving Club Samobor has explored different parts of the Dinaric karst during ten years of its activity. Here is given a comparison between caves in the Vrdovo vicinity (Dinara Mt.) as part of the Outer Dinaric high karst and at the Žumberak Mts. as a part of the Inner Dinaric shallow karst in Croatia. Dinara Mountain represents natural and historical border between Croatia and Bosnia and Herzegovina. The whole karstic region from Italy to Albania was named after it. It is a part of the Outer high karst Dinarides and belongs to the Dinaric carbonate platform (Dinaricum) structural unit. Speleological researches of southeastern parts of Dinara Mt. were carried out from 2007 at the karstic plateaus Vrdovo and Podi, and around Bitelić, Rumin, Priorice and Malin. We have explored thirty-two caves there among which dominate pits (73%). All caves were formed in limestones, mainly Cretaceous age, what is in accordance to the rest of the Croatian karst. According to the morphological type simple caves dominate (73%), followed by the knee formed caves (15%). The longest explored is a cave system Crvenkuša and Tamnica (caves) and Suhi Rumin (pit) with a total length of 430 m. With the 140 m explored depth Jama u Konjikuši Gornjoj pit is the deepest at the moment, although one can expect much deeper pits like adjacent Nevidna voda (-653 m, Dinara Mt., Bosnia and Herzegovina). The most of the caves are dry, and all the types of cave sediments are present within them. By the richness of speleothems stands out Bila Lipotica cave and its final hall. This research also found intensive pollution of the karst underground by the various waste including mines and explosives (e.g. Smrduša Gornja, Smrduša Donja, Buljanov Ponor, Tumbas, Krstačka). Žumberak and Samoborsko gorje Mts., or Gorjanci in Slovenia, is a mountain range bordered by the rivers Krka, Sava and Kupa. Its biggest part belongs to the Nappe of the Supradinaricum structural unit upon the Dinaricum structural unit that is exposed only at the westernmost part of the researched area. Žumberak and Samoborsko gorje Mts. belong to the Inner Dinaric shallow karst. The Croatian part of the terrain was explored in detail from 1975. by the Speleological Section „Japetić“ Samobor whose tradition continued the Caving Club Samobor. A hundred-eighty-two caves and pits were explored to date of which 55% caves. The most of them were formed in Upper Cretaceous carbonates, what is in accordance to the rest of the Croatian karst. According to the morphological type simple caves prevail (76%) and the knee formed caves (10%). They are followed by branching (9%) and level caves (4%). The complex caves are the least numerous (1%), and no system was found to date. The longest is Provala cave (1862 m long and 57 m deep) and the deepest is Bedara cave (1019 m long and 113 m deep) at the moment. There is more groundwater at this area, so 11 caves are permanent springs, and 8 are periodical springs. All types of caves sediments could be found in explored caves, but by the richness of speleothems stand out Jamina and Pušina caves. The waste insertion is a big problem here also and some caves are completely buried with it (e.g. Dubićeva znetva, Mesaruša…). Caving Club Samobor continues its researches at the both of the terrains, where is expected the discovery and exploration of deeper pits in the peak part of Vrdovo. The most noticeable difference between caves of the Outer and Inner Dinarides is in the relationship of pits and caves what is in accordance to the knowledge of the Dinaric karst.
