Abstract

Abstract

It is a common phenomenon that the structural heights in the overburden and substrate evaporite layers are not in agreement with each other in the salt tectonic areas. Two kinds of relationships between structural heights in the overburden evaporite and those in the substrate evaporite in the forelands, where evaporite experienced the deformation, were established in line with the differences both in the boundary stress states and in the rock rheology. When an orogenic wedge underthrusts the evaporite-bearing foreland basin fill, the troughs of overburden synclines will directly match the peaks of substrate anticlines. When an orogenic wedge overrides the evaporite-bearing foreland basin fill, the back-limbs of overburden anticlines will match the peaks of substrate anticlines, and the peaks of overburden anticlines will match the front-limbs of substrate anticlines. Finally, the discussion of the petroleum implication for the two relationships was based on the petroleum exploration in Kuqa foreland.
