Paleokarst and associated sediments at Dubci geosite in Dalmatia, southern Croatia

This short paper brings preliminary results of sedimentological study of Dubci bone-breccia site as an update to former research. The study site is located on the saddle between the mountains Omiška Dinara and Biokovo 404m a.s.l. The site was discovered already at the end of 19th century during road construction between Makarska and Zadvarje. The road cut exposed a cross section through a paleocave covered with coarse clastic sediments in alternation with paleosols. The Dubci site is of Cromerian age (Malez, 1967), one of several Lower Pleistocene sites in Dalmatia with bone breccias rich in fossil skeletal elements of macr mammals and micro mammals. Detailed geological context of the Dubci site was first described by Malez (1967). More recent study of the site indicates even more complex origin of this paleocave and associated sediments, which comprise three sedimentary units. New sediment samples revealed presence of well preserved ostracod fauna, glass spherules and microtectites of probable impact origin, black glass shards, rare microscopic fish bones, benthic and pelagic foraminifers, and particles of various allochthonous lithologies, which all give new input for interpretation of the Dubci site.
