Deep Structures and Their Constraints on Gold Mineralization in the Zhaodagou Section of the Taibaimiao Gold-ore Area Southern Shaanxi Province

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.
