准噶尔中东部地区深部电性结构电磁探测
|
摘要
为了解准噶尔盆地深部构造特征,综合利用"深部探测技术与试验研究(SinoProbe)"项目在准噶尔盆地45°N 88°E处建立的大地电磁标准点实测资料,应用非线性共轭梯度法(NLCG)对该测站两条短剖面进行二维反演,结合新疆准噶尔盆地区域地质资料,对该地区地层电性结构进行了初步分析,发现准噶尔盆地中东部地区地下结构具有很好的电性分层.与现有地质资料相结合,分析发现其电性分层与地壳分层具有较好的对应.根据岩石层电导性推断:研究区域莫霍面埋深在46km附近,岩石圈厚度在100km左右.研究结果对准噶尔中东部地区深部地壳结构的认识具有一定的参考价值.
In order to understand the deep structural characteristics of Junggar basin,the conductivity structure of the region is analyzed in the paper using MT data obtained at standard points(45°N 88°E)in Junggar Basin based on SinoProbe project.Employing the method of nonlinear conjugate gradient for a 2Dinversion of two short profiles in the study area,and analysis of the regional geological data,it is found that the ground has a good electrical layered structure in the middle-east Junggar Basin.A comparative analysis of the electrical layer and the crustal structure is made on the basis of geological data,finding that they show good consistency.Finally,it is concluded that the Moho depth is about 46km,and the thickness of the lithosphere is about 100km.The results can better the understanding of deep crustal structure in Middle-East Junggar Basin.
