摘要

A magnetotelluric sounding (MT) profile from Fengcheng of Shanghai to Huzhou of Zhejiang province was conducted using GMS-06 surveying system, high quality long period data over 4 000 s were obtained. By inversion and processing, these MT data provide basis for the studies of deep electrical and fault structures. The styles of several large and deep faults such as Huzhou-Suzhou, Wuzhen-Majin, Fengjing-Chuansha and Taicang—Fengxian and their roles in controlling the regional tectonics are evaluated. The fault of Fengjing-Chuansha controls the nappe transition structure zone between Shanghai uplift and Huzhou-Nantong arched area.
