Abstract: - The paper identifies geochemically the petroliferous system Histria on the Romanian shelf of the Black Sea from the extension the orogene from north Dobrogea. This petroliferous system consists from the following two subsystems: the first is of generation-expulsion type and is formed by the oligocene source rock and the second one is of migration-accumulation type and is formed by the accumulations of gases and oil which belong to the

Among the paleontological reservations, the ªcheia area (located 25 km south of city of Iaşi, in NE of Romania) marks an outstanding representative Sarmatian fossil association, in the Moldavian Platform (Eastern Paratethys). The area was declared as natural reservation in 2004 (Romanian Government Decision no. 2151/2004) and is actually managed by the Local Council of the ªcheia village. The reservation belongs to the IVth category, according

The association of macro- and microflora founded in the outcrop from Stan hill; Hill is of the Basarabian age. It consists of 12 taxa of macroflora and 66 palynological taxa. Ther was observed a domination of monocotyledonous angiosperms represented by Typha(among the macrofloristic taxa), the Daphnogene gender being for the first time mentioned in the Sarmatian of the Moldavian Platform. Among the palynomorphs there were identified taxa belonging

In the present paper, 10 samples have been analyzed and the resulting palynological assemblages have been interpreted in order to determine the palaeoclimatic conditions during the sedimentation of the studied deposits. In the RBN 4 borehole, we have identified taxa such as the following: Pityosporites labdacus, Pityosporites alatus, Pityosporites insignis, Pinuspollenites miocaenicus, Abiespollenites sp., Myricipites bituitus, Tricolpopollenites
