Morphogenesis of the karst system of the Crnopac massif (Velebit, Croatia, Dinaric karst)

The Crnopac massif is the southernmost part of the Velebit Mountain in Croatia. The aim of this work is to determine the forms, conditions and processes of morphogenesis of this karst system. The emphasis is on the surface and underground geomorphological features. The mapped karst forms of Crnopac include dolines, uvalas, karst towers, dry and blind valleys, and denuded caves. There are more than 300 caves in this area. The longest is Cave System Crnopac (> 55 km), the longest cave in the Dinaric karst. The development of the karst system is related to the relative tectonic uplift of the Crnopac massif. This led to a lowering of the level of allogeneic water input into the system and consequently to the formation of lower active conduits. In parallel, denudation of the surface was also active, lowering the level of the surface. Autogenous seepage of meteoric water from the surface led to the formation of vertical channels that intersect inactive channels. Geomorphological indicators suggest that this process did not take place with uniform dynamics.
