Characteristics of ore-control fracture and contributing factors of gold ore in Wudarehu area at north margin of the Chaidamu basin

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.
