| 摘 要： | 以哈尔楚鲁图银-多金属矿床为例,阐述了甚低频电磁法(VLF-EM)在覆盖区控矿构造特征分析及隐伏矿体找矿预测中的应用。VLF-EM测量和地质解释成果表明:矿区内断裂构造主要有NWW、NNW及NE三个方向。其中,NNW和NWW向断裂为主要含矿构造,二者构成菱形网格状或雁列式控矿构造基本格局,断裂交汇地段为形成较大矿体的有利地段;NE向断裂未见工业矿体产出,对矿体起到错断和破坏作用。

| Abstract: | The Haerchulutu Ag-polymetallic deposit is located at Keshiketeng banner, Inner Mongolia. Based on the study of ore-controlling geological conditions and by means of VLF-EM, the ore-controlling structural characteristics are depicted, and forecasting for buried orebodies in the covered areas is carried out. The VLF-EM survy results and geologic interpretation show: 1. The structural belts in the mining area mainly tend to NNW, NWW or NE, 2. The NNW-and NWW-trending faults are of ore-bearing structures, which consist of lozenge-shaped or net ore-forming structural pattern, 3. Potential ore-finding areas are the intersecting positions of NNW and NWW fractures. |
