东沟—海城—林西—锡盟深地震测深剖面是我国布设的十二条地学大断面中的一条,全长约一千多千米,是我国东北南部地区又一条大的深地震测深剖面.剖面跨越华北地台、内蒙吉黑断褶带两个I级大地构造单元,近似垂直的穿过赤峰—开原等十二条深大断裂.并通过海城、敖汉地震活动区.测线经过高山、平原、沙漠地区,地形地貌条件十分复杂.根据地学断面的要求,在该断面上要开展深地震测深、大地电磁测深、重力与航磁和地震地质等工作,并要求物探方法的探测深度达到M面以下的上地幔.该断面的东段闾阳
The Donggou-Haicheng-Linxi-Ximeng Deep Sounding Depth Profile is one of 12 large geoscientific sections in our country with a total length of about 1000 km. It is another large deep earthquake in the southern part of northeast China Sounding profile, with two I-tectonic units located in the North China platform and the Nei Mengji fault-fold zone, crossing approximately 12 deep deep faults such as Chifeng-Kaiyuan in the vertical direction and passing through the Haicheng and Aohan earthquakes According to the requirements of geosciences section, depth seismic sounding, magnetotelluric sounding, gravity and aeromagnetic and seismic geology should be carried out on this section, And require exploration of geophysical methods to reach the depth below the M-face of the upper mantle of the eastern section of Lu Yang
