Based on the studies of petrotexture, structural deformation and the relevant metamorphism, this paper indicates that this peridotite massif is the product of ultramafic magma cumulated at the crust - mantle transtion zone and has undergone the early stage of plastic deformation under the condition of granulite facies （ 800 ） and late ductile shearing at amphibolite and greenschist facies in relevance to uplifting
本文通過巖體的結構、構造變形及相應的變質作用研究，提出了該橄欖巖體是由超基性巖漿在殼幔過渡帶結晶而成，並經歷了與圍巖一致的麻粒巖相（ 800 ）條件下的早期塑性變形以及角閃巖相和綠片巖相退化變質條件下與逆沖上升有關的韌性剪切變形。 -

In the light of tectonic evolution stage and metallogenesis, these metallogenic system ( assemblage ) could be classified as follows : ( 1 ) the pre - divergent metallogenic system in the southwest margin of north china paleocontinent in the archean - meso proterozoic : dongdashan iron, jinchuan nickel - copper. ( 2 ) the divergent metallogenic system in the northern margin of the qaidam paleoplate in the middle - late proterozoic : huashugou - liugouxia iron. ( 3 ) the metallogenic system in the active margin in the early paleozoic : the metallogenic assemblage in the island arc - rift in the early stage ( baiyinchang - qingshuigou copper - polymetallic ) ; the metallogenic assemblage in island arc in the middle - late stage ( honggou - jiaolongzhang copper - polymetallic ) ; the back - arc extensional basin ( zhuzhuiyaba - jiugequan - shijuli copper ) ; the metallogenic assemblage in connection with subduction and magmatic - hydatogenesis ( taergou - xiaoliugou wolfram ; huashugou - liugouxia copper ; dadonggou - diaodaban lead - zinc ) ; the metallogenic assemblage is related to the oceanic crustal shards ( dadaoerji chromite ; yushigou chromite ). ( 4 ) the metallogenic system has something to do with collision - type orogeny : the metallogenic assemblage in foreland basin ( tianlu copper ) ; the metallogenic assemblage with the intracontinental orogeny and ductile shear ( hanshan - yingzhuishan gold )

All the gold is hosted by different parts of the qiumingtashi - huashan ductile shearing zone. the deformation can be divided into three stages : ductile shearing deformation, brittle - ductile shearing deformation and brittle shearing deformation, in which brittle - ductile shearing deformation stage is the preferred mineralizing stage
及金礦化體均賦存於秋格明塔什黃山韌性剪切帶的不同部位，其變形期次可劃分為3期，即韌性剪切變形、脆韌性剪切變形和脆性剪切變形，其中脆韌性剪切變形階段是最有利的成礦階段。 -
Exhibition of the deposit is controlled by the regional ductile zone, and the ore ' s distribution has been controlled by the secondary ductile zone ( controlled mine ductile zone ), the brittleness structure of later stage possess the specified reconstruction and damage to the mineral ore, at the same time it also strengthened gold once more wealthy anthology
區域性韌性剪切帶控制了礦床的展布，而次級韌脆性剪切帶（控礦剪切帶）控制了富礦體的分佈，後期的脆性構造對礦體有一定的改造、破壞作用，同時也加強了金的再一次富集。
