GEOLOGICAL AND PALEONTOLOGICAL HERITAGE OF THE MOLDAVIAN PLATFORM, NE ROMANIA

(STEF92 Technology, 2021-12-20, Andrei Briceag, Mihaela Melinte‐Dobrinescu, Antoneta Seghedi, Iulian Pojar, Eliza Anton)

The Moldavian Platform represents the south-west margin of the East European Platform. To the south, the Moldavian Platform is bordered by the Scythian Platform and to the west by the Carpathians. The Moldavian Platform encloses many geological and paleontological sites of high scientific value, being well known for the Middle Miocene wide exposures, represented by the Paratethys stage Sarmatian. In this study, we present the geological and paleontological heritage of 6 natural reserves from the Moldavian Platform...

HEAVY MINERAL ABUNDANCE AND DISTRIBUTION IN FLUVIAL DEPOSITS OF THE SAINT GEORGE BRANCH, DANUBE DELTA, ROMANIA

(STEF92 Technology, 2021-12-20, Iulian Pojar, Cătălin Gheablău, Laura Tiron Duţu, Andrei Briceag, Florin Duțu)

Show more

Heavy mineral concentrations formed in fluvial deposits present the signature of the mineral provenance and of the hydraulic sorting during transport and accumulation. The sedimentary discharge of the Danube River has been preferentially deposited due to the mineral physico-chemical properties, such as size, morphology and density, as well as local hydrodynamic factors. Besides these natural aspects, the recent modifications of the Danube and its deltaic branches are associated with a significant remodelling of th...

SEDIMENTOLOGICAL INVESTIGATIONS ON ST. GEORGE DISTRIBUTARY, DANUBE DELTA, ROMANIA

(STEF92 Technology, 2021-12-20, Iulian Pojar, Bogdan Ispas, Laura Tiron Duţu, Andrei Briceag, Florin Duțu)

Show more

Taking into account the sedimentation features since the last 5 decades, considerable anthropic modifications on the Danube channel are present, as the debris composition varies concerning the proportion of terrigenous minerals, lithoclasts, bioclasts and organic matter. Since the 7th decade of the last century, marked by the construction of most hydrological power plants on the Danube, Olt, Jiu, Cerna and other major rivers, a significant change of the sedimentary volume brought downstream by the Danube is assume...

THE VERTICAL DISTRIBUTION OF THE MAIN LIMNOLOGIC PARAMETERS, AS EVIDENCE OF RECENT LACUSTRINE SEDIMENTATION IN MATITA-MERHEI UNIT-DANUBE DELTA, ROMANIA

(STEF92 Technology, 2021-12-20, Irina Catianis, Adriana Maria Constantinescu, Sabin Rotaru, Iulian Pojar, Dumitru Grosu)

Natural processes and human influences can cause several environmental issues upon urban and rural aquatic systems, especially in deltaic environs. This study was aimed to assess the vertical variation in the physical-chemical and lithological characteristics of core sediments. 14 undisturbed short sediment cores were collected from soft lacustrine sediments in various shallow lakes situated in the Matita-Merhei interdistributary depression, Danube Delta, Romania. Sediment samples were measured for temperature, pH...
