The Oligo-Miocene basin of Sivas (Turkey) is a new choice analogue for the study of salt tectonic with outstanding outcrops reflecting the variety of salt related structures: minibasins, diapirs, welds....

A 3D geological model of the Inceyol mini-basin was built thanks to a subtle combination of various techniques available in RING's plugins :  VorteXLIB for vomumetric meshing, StructuralLab for implicit modelling using various constraints and weights, and Gopy for automation of Surface extraction.

Located on an ancient salt extrusion, the Inceyol mini-basin is approximately 700 m wide by 800 m long. It is filled by more than 300 meters of saline lacustrine to sebkhaic deposits of Oligocene age. The mini-basin is structured as an encased system of synclinal folds displaying an elliptical shape in overall outline. In more details, the mini-basin forms a single syncline in the north that splits to the south into two individualized tight synclines. The two synclines are separated by an exposed gypsum wall, interpreted at depth as a weld or a thin wall. At the outcrop, both sides of the salt wall are marked by steep to overturned flanking strata.

The resulting 3D model highlights the remarkable geometry of this salt-tectonic related structure and underlines the usefulness of new modelling methods to ease a more automated generation of such tectonic features.
