Abstract:Kumgeliemu Groupe,lower part of Tertiary in Kuche depression,is a set of huge thickness of gypsum salt that caused inconsistent deformation between overburden of salt and subsalt layers,which is evident in Kelasu tectonic zone. It's proved by seismic sections and drilling practice that the structural highs of overburden of salt and subsalt layers exit two corresponding relations , that is structural highs (anticlines)in overburden of salt are corresponding to the synclines in subsalt layers and anticlinal flanks of overburden are corresponding to anticlinal highs in subsalt layers. These corresponding relation of highs is related to contacting relation between Kuche foreland fill and Tianshan orogenic wedge. The highs (anticlines) of overburden of salt corresponds to front-flank of subsalt anticlines and back-flank of overburden to subsalt highs when the foreland fill thrusted beneath the Tianshan orogenic wedge;on the contrary, the structural highs of overburden of salt corresponds to subsalt synclines and synclines of overburden to subsalt anticlines. From the respect of petroleum exploration,the former is of benefit to preservation of oil that is favorable zone of oil prospecting.
