Abstract

Sedimentological, macro- and micropaleontological analyses on sediment cores were carried out in the lower section of the Mirna and Neretva River valleys, in order to study depositional facies and environmental evolution during Late Pleistocene and Holocene. The Holocene marine transgression reached river valleys several kilometers upstream from the present-day coast, while in the last 7000 – 6000 years it was followed by progradation of the Mirna and Neretva intra-estuarine deltas. Sediment cores recorded these changes and each depositional environment contains distinctive sedimentary characteristics and fossil assemblages which reflect conditions in which sedimentation and life were occurring. This study highlights the potential role of hand augering in sampling and describing the subsoil for reconstruction of the geomorphological evolution of the area and supporting the study of past relative sea levels, climate changes, and impact of anthropogenic activities.

Abstract (croatian)

Sedimentološke, makro-paleontološke i mikro-paleontološke analize radile su se na sedimentnim jezgrama izvađenim iz deltnih ravnica rijeka Mirne i Neretve, s ciljem da se prouče i rekonstruiraju taložni facijesi i evolucija okoliša tijekom mlađeg pleistocena i holocena. Transgresija u holocenu dosegnula je uzvodno u riječne doline nekoliko kilometara od današnje obalne linije, a u posljednjih 7000-6000 godina uslijedila je progradacija delti u estuarijima rijeka Mirne i Neretve. Sedimentne jezgre sadrže zapis tih promjena, a svaki taložni okoliš sadrži karakteristične sedimentne značajke i fosilne zajednice koje odražavaju uvjete u kojima se odvijala sedimentacija i život. Ovo istraživanje naglašava potencijalnu ulogu ručnog uzorkovanja jezgri u opisivanju sedimenata, u svrhu rekonstrukcije geomorfološke evolucije područja i upotpunjava znanje o promjenama relativne razine mora, klime i utjecaja antropogenih aktivnosti.
