MINERALOGY OF THE BOTTOM SEDIMENTS IN THE CENTRAL AREA OF THE BLACK SEA SHELF.

- Abstract
GeoEcoMar Programmes (Acronyms: GEOMAND and FLUDITMAR) represented the financial support for the marine scientific activities, including the mapping of the Romanian shelf area. The drawing of the sedimentological maps, scale 1:50.000, includes the mineralogical analyses of the bottom sediments of the Black Sea, with a special attention for the heavy minerals associations. For the central part of the Black Sea shelf area, the main contributors in heavy minerals are the solid discharge of the River Danube and, partially, the northern longitudinal marine current. Source areas of heavy minerals are the geological basement of the River Danube drainage basin and the old geological formations of the Scythian Platform. The distribution of the sandy sediments, siliciclasts and heavy minerals are presented in some thematic maps. The erosion of the palaeo-beaches, located in the basement of the Holocene sediments of the Danube Delta complex, favours the diversity of the heavy minerals associations.
