| 摘 要： | 铜冶店孙祖断裂展布方向与区域上基底岩石的条带展布方向一致,该断裂规模巨大,总体上分为6段,作为构造单元边界的分划性断裂往往深切上地幔或下地壳,从而成为深部岩浆和矿液的上升通道。它控制着该区成矿带或成矿区的分布,金牛山岩体、矿山岩体、铁铜沟岩体、铜井岩体等中基性—中性—中偏碱性(中偏酸性)杂岩体亦是受铜冶店孙祖及其次级断裂或与其他构造复合部位控制。该断裂经历了多期活动,早期活动控制着两侧地质体的分布,晚期活动对各种含矿热液的运移和富集起着不同程度的控制作用,是铁、铜、金矿成矿作用的有机组成部分,“构造、地层、岩体”三要素是形成接触交代(矽卡岩)型铁矿等矿床必不可少的控矿因素。该断裂活动提供了成矿物质和流体迁移、聚集的热力和动力,提供了成矿物质运移和沉淀的空间场所,其所控制的矽卡岩型铁矿床及中低温热液金、铜等矿床,多集中于铜冶店孙祖断裂鹿野前孤山段,该断裂具“构造控矿,分段富集(走向、倾向)”的特点。

| 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). |
