摘要: 赵大沟矿段各矿体的产出与分布严格受北西西向压扭性断裂(F1~F5)控制。成矿作用早期形成的张性构造裂隙是矿体的主要赋存空间,无论矿体还是张性裂隙均在深部显示为沿北西西向压扭性断裂断续延伸的规律,反映了在北西西向压扭性(F1~F5)断裂所经过矿段的深部还有延续。因此,赵大沟矿段构造控矿标志明显,预测与其相邻的赵大沟以西地区和金洞沟地区地表及深部具有相似的赋矿规律和找矿标志,应作为今后主要的找矿远景区。Abstract: The output and distribution of ore bodies in Zhaodagou ore section are strictly controlled by the NWW-direction F1~F5 compressive-shear fault. The tensile fracture formed in early ore-forming stage is the main accumulating space of ore body. Regardless of the ore body or tensile fracture, both of them in deep area show the intermittent extension along the F1~F5 fracture, reflecting that there is extension in the deep area of ore section that F1~F5 fracture passes through. Therefore, the structural ore-control sign of Zhaodagou ore section is clear, and it is predicated that it has the similar ore-accumulating rules and prospecting sign in ground surface and deep area with the neighboring western area of Zhaodagou and Jindonggou area, which can be regarded as the main prospective area to look for ore body.
