| Isotope Geochemistry of the Xiaoxinancha Gold and Copper Deposit |
| Lying in Hunchun County,Jilin Province,the Xiaoxinancha deposit occurs in the contact zone between the Late Variscan diorite and Lower Paleozoic Wudaoguo Group. Based on the research of isotope ratios of lead,sulfur,oxygen and carbon in the ores and rocks of this area,it is held that Qinglongcun Group serve as the source bed of gold. The polymetallic deposits of porphyry,skarn and hydrothermal types were formed during the remelting of Qinglongcun Group in the Variscan period and the mixture of hydrothermal activity and atmospheric precipitation in the Yanshanian period. Isotopic analysis of gold-copper deposits is very important in prospecting for original deposits in Xiaoxinancha area and providing essential geological data for further research. |
