Abstract:The distribution direction of Tongyedian Sunzu fault is consistent with that of basement rocks in the region. The fault has a huge scale and is generally divided into six sections. As the boundary of tectonic units, divisional faults often cut deep into the upper mantle or lower crust. Thus, it becomes the ascending channel of deep magma and ore fluid. It controls the distribution of metallogenic belt or metallogenic area in this area. The intermediate-basic-neutral-alkaline (intermediate-acidic) complex, such as Jinniushan rock mass, mine rock mass, Tietonggou rock mass and Tongjing rock mass are also controlled by TongyedianSunzu fault, its secondary faults and other structural composite parts. The fault has experienced multi-stage activities. Early activities control the distribution of geological bodies on both sides, while late activities control the migration and enrichment of various ore-bearing hydrothermal fluids in varying degrees. It is an important part of the mineralization of iron, copper and gold deposits. "Structure, stratum and rock mass" are indispensable ore-controlling characteristics for the formation of contact metasomatic (skarn) type iron deposits. The activity of the fault provides the heat and power for the migration and accumulation of ore-forming materials and fluids, as well as the space for the migration and precipitation of ore-forming materials. The skarn-type iron deposits are controlled by the fault. Low and medium temperature hydrothermal gold and copper deposits are mostly concentrated in LuyeQiangushan section of Tongyedian-Sunzu fault. The fault has the characteristics of "tectonic ore-controlling, section enrichment" (strike and tendency).
