Change in tectonic stress magnitude (negative, nil, or positive) inverts the relative position of the effective main stress axes. Microtectonic data, mechanical laws, structural field geology, and seismic reflection data are compared. These studies show a close relationship between tectonic style, strike of the structures, fault movements, and regional tectonic regime, i.e., orientation, relative position of the main stress axes at the time of deformation, and magnitude of the tectonic stress. Thus, the structural styles in a sedimentary basin can be classified as a function of the tectonic regime in the absence or presence of shale or salt tectonics. These styles are illustrated with strike and dip seismic sections, which allow us to predict the style and evolution of structures in petroleum sedimentary basins.

One method for validating the geometry of geological structures is the balancing cross-section technique which allows verification of cross-section geometry by a return to its initial horizontal state. However, this can not be used for of 3D halokinesis,

The geochemical oil and gas characterizations were based on bulk analyses, chromatography (liquid and gas), mass spectrometry and mass spectrometry-coupled to stable carbon isotope ratio determination.

During the Messinian Salinity Crisis (5.96-5.33 Myr), the Mediterranean Sea reduced progressively its connection with the global Ocean by a complex combination of tectonic and glacio-eustatic processes. During this period, deep erosion occurred on the margin and on the continent. Furthermore, a large quantity of evaporites was

The front of this tectonic wedge is characterized by transfer zones of various scales and geometries. The

The approach is to restore the geological layers in their initial deposit positions. If this restoration is possible, the hypothesized interpretation may be correct. If the restoration is impossible or unrealistic, the interpretation will be wrong. Basically, the restoration process assumes the layer's surface
