Abstract: Sequence Stratigraphy Analysis of Depositional Successions, Depositional Environments, and 3D Building Model of the Badenian, Sarmatian and Meotian in the south - western part of the Dacic Basin

GAGEANU MAIA, PETROM

Integration of the cores (sedimentological descriptions and paleontological data) with well log and seismic data have been used to provide a new conceptual depositional model for the Neogene (lithostratigraphy and depositional environment in the western part of the Dacian Basin).

This area has intensively been cored, so information is based upon observed lithologies and correlations of surfaces, as well as matching log patterns.

Brief sedimentological descriptions and discussions of lithofacies geometries and distributions will be keyed to some cross sections. The cross sections are a genetic stratigraphic summary derived from complete sedimentologic descriptions of facies, regional facies interpretations, depositional environments and basin-scale maps.

Assemblages of individual facies that occur together on the cross sections will be described from west to east, or from landward to seaward (marginal to nonmarine, shore zone, basinward).

Sequence stratigraphic surfaces (as interpreted in the context of the hypothesis of this poster) are also labeled; however, these designations are interpretations of the unconformity-bounded sequence.

Genetic stratigraphic units, once defined, were correlated with lithostraigraphic units and a framework was recognized for the depositional environments. environment in the western part of the Dacian Basin).
