柴达木盆地北缘乌达热乎地区的金矿床（点）主要受本区断裂构造控制,区内金的活化、迁移受控于与矿床所在构造破碎带基本平行展布的嘎顺—乌达热呼韧性剪切带,金矿体主要赋存于韧性剪切作用之后的脆性断裂之中。根据包裹体测温、稳定同位素特征以及岩石地球化学等资料分析,成矿物质主要来自本区滩间山群绿片岩,其成因属与绿片岩有关的韧性剪切带型金矿床。

The gold ore deposit in Wudarehu area at north margin of the Chaidamu basin is controlled by the fracture structure.The activation,move of gold in the area is dominated by the shear zone which parallels crushed zone where the deposit lies.Gold ore distributes in brittle fracture which formed after ductile shearing.Based on analysis of temperature measuring test on inclusions,stable isotope and lithogeochemistry,ore-forming substances are mainly from mountain group greenschist among swashes.It is greenschist-related ductile shear zone gold ore deposit.
