Variability and Main Controlling Factors of Hydrocarbon Migration and Accumulation in the Lower Paleozoic Carbonate Rocks of the Tazhong Uplift, the Tarim Basin, Northwest China

Figure 4

Profile of the carbonate rock fault unconformity pathway system of the Tazhong Uplift. Unconformities are found on the top surface of the carbonate formations and at interlayer karst fracture cavities between the formations, representing a favorable pathway system for the lateral transportation and adjustment of oil and gas.
