应用重、磁、震、测井等综合物探资料,研究了准噶尔盆地东部基底结构的形成机制与古地温场的关系。指出基底拆离运动是引起本区古地温梯度场增高的主要因素,它对有机矿产资源和地热资源的形成有重要作用。

The relation between basement structure forming mechanism and paleo geotemperature field in eastern Zhunger Basin is researched using integrated geophysical data such as gravity, magnetic, seismic and well log data. It is pointed out that the basement seperation movement is the main factor of causing the increasement of paleo geotemperature gradient field in the area and this plays an important role in the forming of organic mineral resources and geothermal resource.
