Geological Mapping and Investigation into Tectonic Control on Deposition in an Active Rift Setting. The Doumena Fault Block, Greece.

The Doumena Fault Block (DFB) is one of a series of sediment filled rotated half grabens within the Gulf of Corinth rift system that exposes excellent outcrops of syn rift strata.

Previous studies of the fault block raised questions regarding the structural evolution and sedimentation interaction. However, these studies mostly focused on large alluvial fans present in the eastern side of the block. The rest of the fault block and the DFB's relation to the adjacent blocks have not been studied in detail.

The main objective of this project is to study the tectonic control on sedimentation and establish the relative age of the different units in the DFB's. This project can improve the understanding of the geological evolution of the DFB, and contribute to the general understanding of sedimentation within extensional rift systems.

To accomplish the goals, geological mapping and facies interpretation of the Doumena Fault Block was performed. In addition, a 3D structural facies model was created in Petrel. The model allowed us to better understand the three dimensional configuration of the fault block and create different scenarios on how the alluvial fan deposits and the basal unconformity have been influenced by fault evolution.
