The main purpose of this paper is to provide new geological information and interpretation of the well data from the Istria Basin, Western Black Sea. Therefore, we present a reconsideration of the microfaunas (mainly foraminifers) and calcareous nannofossils described from several wells drilled on the Lebada East structure belonging to the Istria Basin, by using core reports. Thus, we have been able to compile integrated information regarding the lithology and biostratigraphy of the wells. We have focused on the s...

Water quality was investigated in Lake Matita, part of the Danube Delta Biosphere Reserve, Romania, to assess the overall status of the freshwater ecosystem, in accordance with the EU Water Framework Directive (WFD ? 2000/60/EC), which addresses all surface waters i.e., rivers, lakes, transitional waters and coastal waters in the EU. From this perspective, a specific physical and chemical analysis of surface water samples was performed, collected in different sectors of the lake, during the summer of June 2020. Se...

The Southern Dobrogea is situated in SE Romania, being included, tectonic point of view, in the Moesian Platform. The Southern Romania is bordered by the Danube to the West and the Black Sea to the East. In the N, the Southern Dobrogea is bordered by the Capidava-Ovidiu subcrustal fault; towards south, it continues to the northern Bulgaria. In the Southern Dobrogea, a carbonate platform developed from Mesozoic (Upper Jurassic and Cretaceous), and continued through the Paleogene up to the Miocene. The Pliocene is m...

The paper presents well-preserved microfaunas (foraminifers and ostracods) enclosed in cuttings samples and cores recovered by 6 hydrocarbon wells drilled in the Moesian Platform, in Silistea area, S Romania. The lithological and micropaleontological obtained data improve the stratigraphic knowledge at regional level. The analyzed samples contain foraminifera that characterize biozones extending in the Sarmatian, as follows: the middle Volhynian Varidentella reussi, the late Volhynian Elphidium reginum, the early ...
