HYDROTHERMAL ORIGIN OF ZADLAŠKA JAMA, AN ANCIENT ALPINE CAVE IN THE JULIAN ALPS, SLOVENIA
Abstract:

Zadlaška Jama was formed in an aquifer below the water table level as a dense network along bedding planes and fractures. It is an anastomosing network system of horizontal and vertical tubes. A selection of tubes grew into larger passages. In addition to the speci?c fracture controls, did hydrothermal water flooding the cave from below, contribute to the development of its dense network of passages? PALMER (1995) observes that when water rich in sulphur mixes with water rich in oxygen in zones of fractured rock, initial cave networks develops. Water from the spring below Zadlaška Jama (Figure 1) has a high carbonate and potassium content and total hardness (400 mg/l); chlorides are somewhat higher in the content as is the proportion of sulphates (40 mg/l). DUBLYANSKY (1989) found that water less than 20o C – in this cave temperature of water is 20.7o C - does not cause distinct development of hydrothermal karst, although mixing of waters with different characteristics and temperatures frequently can cause the development of network maze cave systems (DUBLYANSKY, 1997). FORTI (1996) describes the formation of a three-dimensional cave system that was the consequence of mixing thermal water at a declining water table level with percolating water from the surface. At Zadlaška Jama such a mode of cave formation can only be attributed to its early stages, while all other forms are those of varying fast water flows and of filling of the cave with fine grained sediment.
