Abstract
The Dachstein limestone from Krn is characterized by Lofer development. The section encompasses 30 cyclothems on average 3-4 metres thick. Intraand supratidal environment of deposition is evident by stromatolites, loferite and tem pestile breccias. They were all locally affected by early diagenetic dolomitization. Biomicritic limestone with several horizons of megalodont clams was deposited in shallow and restricted shelf. Basal members A of the Lofer cyclothem are devel oped only exceptionally. Solution cavities are fairly common, being infilled by sparry calcite and insoluble rich red limestone. The limestone was deposited on the Julian carbonate platform near its passage part to the southerly lying Slovenian basin. In this part reigned specific circum stances that resulted into formation of very numerous corrosion vugs; they are filled in their central parts by variegated marly clay.

Highlights
When approaching the middle Soča River area, the eye is caught by vast mountainous massifs of the Julian Alps among which is especially dominant the mighty summit of Krn

These massifs are prevailingly built of the more than 1000 meters thick sequence of light thick bedded limestone that is known in the geological literature as the Dachstein limestone
Summary
When approaching the middle Soča River area, the eye is caught by vast mountainous massifs of the Julian Alps among which is especially dominant the mighty summit of Krn (fig. 1). The development of the Main dolomite and Dachstein limestone in Julian Alps is equal, or very similar as in the wider region of the Northern and Southern Alps (Sander, 1936; Zanki, 1967, 1971; Fliigel, 1963, 1972; Fischer, 1964, 1975; Bosellini, 1967; Bosellini & Rossi, 1974), Dinaric Mountains (Buser, 1974; Ogorelec, 1975, 1988; Ogorelec & Rothe, 1993; Dozet, 1990; Herak et al, 1967; Babič, 1968; Dimitrijevič & D imitri j evič, 1988; Čadjenovič, 1988), Hungary (Ftilop, 1976; Haas, 1994), and even Sicily (Matavelli et al, 1969; Catalano et al, 1974) This is an indication of unique depositional and paleogegraphic conditions in the wide region of the Northern and Southern Alps and the Mediterranean in Norian and Rhaetian times. As the marginal part of the Julian Alps the Krn nappe is thrust over the Rutar nappe (fig. 2)
