摘要
介绍了大地电磁测深在西藏洞错盆地的应用,详细分析了西藏洞错盆地的电性结构特征,分析表明：盆地电性剖面分块明显,沿剖面可以分为4个电性区域,盆地沉积厚度有24 km厚,基底界面呈2个凹陷和1个隆起特征,南北两端存在2条深大断裂,控制着盆地形态,推测盆地南北两端存在推覆现象,推覆断层的上盘向盆地中心方向运动。
The result of magnetotelluric sounding dectection on the profile along Dongcuo basin in Tibetan Plateau shows that the area is divided into four electrical zones,The thickness of the sendiment of the basin is 24 km.The surface of the basement presents two depressions and one dome.The conformation is controlled by two overthrusts through the profile.We conclude overthrusts exist at two sides of the basin,and they move towards central part of the basin.
