| Structural Segmentation of the Foreland Thrust Belt and Its Relations to Hydrocarbon in the Southern Margin of Junggar Basin |
| Characteristics of structural segmentation of the foreland thrust belt in the southern margin of Junggar basin were studied on the basis of a comprehensive analysis of geological outcrops as well as seismic and geophysical data.It is concluded that the main factors inducing structural segmentation in this area are attributed to large-sized basement faults,namely,Urumqi-Miquan fault and Hongche fault,whose formation and evolution determined separately the appearance and/or disappearance of the characteristics of structural segmentation,and that the main factors inducing structural sub-segmentation are attributed to the transfer zones which extend in the directions of NW and NE-NEE in the basin margin.The structural segmentation has played an important role in controlling the hydrocarbon in such aspects as the formation and distribution of source rock and source-reservoir-cap assemblages,and the periods of migration and accumulation of hydrocarbon within different structural segments. |
