Abstract
Namen raziskave je bil morfogenetska interpretacija nastanka in delovanja slepih dolin Hudournika in Goloberta na območju kontaktnega krasa v okolici Dan pri Divači. Za dosego namena smo postavili pet ciljev: pregled strokovne literature o kontaktnem krasu in proučevanem območju, geomorfološka analiza površinskih oblik ter izdelava geomorfološke karte, analiza podzemnih oblik, morfometrična in morfostrukturna analiza območja ter sinteza ugotovitev. Strmec Hudournika je v zgornjem toku višji od Golobertovega. Morfostrukturna analiza je pokazala, da je tektonska struktura pomembno vplivala na potek kanjona Goloberta in na potek jamskih rovov v Mejamah, ki potekajo vzdolž razpoklinske cone ob prelomih. Slepi dolini Hudournika in Goloberta sta začeli nastajati ob vrezovanju in poglabljanju toka Reke v Vremsko dolino. Potoka sta svoji slepi dolini oblikovala v času večje vodnatosti in pred antropogeno prestavitvijo vodnega toka. Pri procesu nastajanja oblik kontaktnega krasa je pomembna kamninska podlaga (stik apnenca in fliša), prisotnost alogenih vodnih tokov, nekarbonatno vodozbirno zaledje, ki je višje od okolice in potek prelomov. Na proučevanem območju je največ oblik nastalo v foraminifernem apnencu. Glede na število tipičnih oblik kontaktnega krasa je proučevano območje tipičen primer kontaktnega krasa.

Title:Geomorphological features of contact karst in the surroundings of Dane pri Divači
Abstract:
The purpose of this study was to define a morphogenetic interpretation of the formation and functioning of the blind valleys of Hudournik and Golobert in the contact karst area in the surroundings of Dane pri Divači. In order to achieve this purpose we have set five goals: review of scientific papers on contact karst and the studied area, geomorphological analysis of surface forms and preparation of the geomorphological map, analysis of underground forms, morphometric and morphostructural analysis of the area, and the synthesis of findings. Hudournik's steepness of waterflow in the upper part of the valley is higher than Golobert's. Morphostructural analysis has shown that the tectonic structure had a significant influence on the course of Golobert's canyon and on the course of the cave channels in Mejame which run along the fractures in the fracture zone. The blind valleys of Hudournik and Golobert started to form when the river Reka (River) cut itself into its riverbed and deepened into the Vreme valley. The two creeks have formed their blind valleys during the period of higher water levels and before the anthropogenic change of the waterflow. In the process of the formation of the contact karst forms in general, the rock base (contact of limestone and flysch), the presence of allogenic waterflows, the non-carbonate water collecting hinterland higher than the surroundings and the course of fractures are important. In the studied area, most of the forms had formed in foraminiferal limestone. Given the number of typical forms of contact karst, the studied area is a typical example of contact karst.
