【摘要】 本文给出了沿辽宁义县—内蒙古东乌珠穆沁旗大地电磁测深剖面的电性结构。研究结果表明,沿该剖面壳内和上地幔高导层的埋藏深度与温度场有着良好的对应关系,即壳内、上地幔高导层埋深愈浅,其热流值愈高,反之就越低。大地电磁测深结果还表明,辽西隆起区继承了辽南地区上地幔高导层起伏形态。本文还从电性结构特征探讨了西拉木伦河断裂带可能是西伯利亚板块和中国板块的缝合线。更多还原

【Abstract】 The magnetotelluric sounding profile from Yixian, Liaoning, to Dong-Ujimqin Nei Mongol, was carried out and the geoelectrical structure along this profile is presented in this paper. The results show that the buried depth of the conductive layers both in the crust and upper mantle is in a good correspondence with geotemperature field data i. e. The shallower the buried depth of the conductive layers, the higher the heat flow value.According to the geoeletrical structure it is supposed that the Siramulen River fault zone seems to be a tectonic suture line between Siberia plate and China plate.更多还原
