摘要

In order to provide the geologic background for exploration of mineral prediction and evaluation over Dongwuqi Hegen Mountains, 26 long-period MT site was laid out with 3~6 km station spacing,along a 100 km profile.On the basis of above analysis, the electrical structure character of crust and upper mantle at depth 120 km of Hegen Mountains ophiolite melange belt is presented clearly. The results show that there are four structure units divided by plate suture zones across the profile, the crust and upper mantle structures of those units are very different.
