Contributions to the knowledge of Quaternary formations in the southwest Romanian Plain

Zoning the alluvial thickness of the Upper Member of the Danube Formation, omnipresent in the Lower Danube Valley, reveals the dominance (69.3%) of the 5-10 m and 10-15 m ranges. Terrace and floodplain alluvia are 15-20 m, 20-25 m and 25-30 m-thick on about 20.5% of the studied area: (i) near Miroć Tableland, on the subsiding sectors divided by faults (ii) stacked alluvial sequences) and (iii) at the confluence of the Blahnita and the Drincea rivers with the Danube Valley (3 stacked alluvial sequences).
