Overview and Reinstatement of Some Geophysical Interpretations in the Eastern Sava Depression

Abstract

The eastern part of Sava Depression is bounded on the south with the Sava River and on the north with Psunj Mountain, Požeška and Dilj Hills. In this part thicker Neogene-Quaternary sediments than in the western part were found, and there is almost never reached thermal maturity sufficient to catagenesis. Therefore, after the first seismic survey and exploratory drilling, a new additional research never continued. The overview and assessment of the reconstruction of the part of geophysical measurements was prepared in the eastern part of the Sava Depression. In some previous interpretations rocks between the Upper Pannonian and Upper Pontian are described as result of deltaic systems, with the clinoforms. Regional deposition at the time of the Early Pannonian indicates the beginning of significant changes in the environment in Croatian part of the Pannonian Basin System (CPBS), with a distinct domination of turbidites. Clinoforms are possible results of especially psammitic detritus deposited toward the margins of the depression, and partly in the direction material transport. In the Early Pontian regionally depositional environments started to be local. In the Quaternary can be expected the existence of the delta or alluvial fans.
