• Sedimentary record
• Transverse fault

The NW-trending transverse faults existing in the northwestern margin of Junggar Basin were proved by the analysis of the sedimentary record around Karamay and Wuerhe combined with previous studies on geophysical, satellite-mapping and graviey-magnetic features of this area. The NW-trending transverse faults together with the NE-trending thrust faults constituted the ';crossover'; structural framework in the studied area. Hydrocarbon migration and accumulation patterns in the area are complex. The transverse faults penetrated into the source centre. Oil and gas migrated along the transverse faults were later vertically adjusted and allocated by thrust faults, high-permeability reservoir rock and unconformity surfaces. The crossover of the transverse and thrust faults is favorable for hydrocarbon migration and accumulation and will become the target for oil and gas exploration.
