摘要
五龙沟以蚀变碎裂岩型为主的金矿床受区域韧性剪切带构造背景控制，产出于北西、北北西向断裂中。控矿断裂属剪张性脆性断层，其发育及分布受控于石灰沟等韧性剪切带，是东昆仑印支期区域走滑作用下的产物。金矿化的构造控制作用主要体现为剪切带的动力作用和脆性断裂作用两方面。
The gold deposites of altered cataclasites in Wulonggou are controlled by reginal ductile shear zone and form in fractures. The fractures which control the deposites are confined by the shear zone. And the deformation is made by the regional strike-slip fault in the east of Kunlun during Mesozonic. The structural controlling in mineralization mainly results from driving force in shear zone and fracturing.
