| Abstract: | This article discusses characteristics,composition of ore body and wall-rock alteration minerals of Cu-polymetallic deposit in Suolagou,Xinghai,Qinghai. Genesis of the deposit was analyzed by the sulfur isotopes,the lead isotopes and homogenization temperature of inclusions. The values of sulfur isotopic (δ34S) are-3.91‰~4.42 ‰,with a mantle characteristics. Lead isotopic characteristics show the orogenic belt in the tectonic pattern and the age of ore is basically the same as that of the regional granites. The temperature of mineral inclusions is 270℃~365℃ by the decrepitation,reflecting the mineralization process is a process of low temperature cooling in the shallow. Summarizing a variety of geological data,we suggested that source material is mainly from Triassic strata. There are two-stages in the deposits including sediment diagenesis and hydrothermal transformation. The genesis of ore deposit is related to magmatism and belongs to sedimentary-transform-type stratabound hydrothermal deposit. |
