The southern slope of Central Uplift Belt is divided into two tectonic units, Katake Uplift and Tanggubazi Depression, which belong to two fault systems. The fault system in Tanggubazi Depression can be subdivided into the western, central and eastern fault areas. These faults mainly developed during the Ⅰ and Ⅲ episodes of mid-Caledonian movement and most of them are thrusting. The faults can be classified into two types, the cap-sliding and basement-involved faults, and they can be further classified into four subtypes, the reversion faults, thrusting-decollement faults, thrusting-decollement-with-strike-slipping faults, and the high-angle thrusting faults. These different faults are superimposed from each other and group into four styles of structures: the fault-related folding structures, buried-hill-draping structures, flower structure and positive reversed structures. The fault-related folding structures are the important exploration targets because they would provide many traps with large area, where the key factor of hydrocarbon accumulation should be if reservoirs develop. The slope areas around the buried-hill draping structures are also favorable targets where one key factor of hydrocarbon accumulation should be if the capping condition is good. It is considered that there would be many types of traps and amounts of potential resource in the southern slope of Central Uplift Belt but because of still low-degree exploration at present in it, exploration investment needs to increase.
