RGIN: 0cm 0cm 0pt" class=MsoNormal>A series of thrust-fold belts were formed in the southern Junggar foreland basin during the Cenozoic. This paper provides regional structural analyses of the thrust fold belts based on the growth strata, interpretation of seismic profiles, and balanced cross-sections, together with available magnetostratigraphic results. The analyses show that three paralleled rows of anticlinal belts have been developed sequentially from the south to the north since ~7 Ma for the southern, ~2 Ma for the middle, and ~1 Ma for the northern anticlinal belt, respectively. The systemic studies of the sedimentary sequences show that the source rocks, reservoirs, seal rocks, and traps between the northern and southern margins of the refix = st1 ns = "urn:schemas-microsoft-com:office:smarttags" />Tianshan Mountains are similar and there are three petroleum systems (or plays) in the southern Junggar Basin. This paper proposes that the lower play, i.e., the Upper Jurassic reservoirs sealed by the Lower Cretaceous, is favorable for forming large-scale oil-gas field and should be potential targets for future exploration.
