| 摘 要： | 甘肃永昌─独青山大地电磁测深（ＭＴ）断面可分为４个岩性电性层和两组“构造电性层”，铲状断裂发育，无超壳深断裂。具深、浅双层推覆滑脱构造。金昌硫化铜镍矿床的合矿超基性岩体与深部通道的联系已被错断，是无根的，是推覆滑脱构造由南而北、由深而浅拖带上来的。

| Abstract: | MT section of Yongchang-Duqing Mountain in Gansu can be divided into four lithologicelectrical layers and two groups of the structure-electrical layers. The latter is located in the top and inner of the base of Pre-Changcheng system, respectively. It develops shrike faults but no deep fractures. It is formed by two groups of nappe-slip structure, one is shallower, another is deeper. The ore-bearing ultrabasic body of sulphide copper-nickel ore deposits in Jinchang is pulled from south to north and from deep to shallow by the nappe-slip structure. It has no root and no connection with the deep thoroushfare. |
