| 中文摘要:小西南岔矿区位于吉林省珲春县，其金铜矿床产于下古生界五道沟群与华力西晚期闪长岩内接触带中。通过对矿区矿石、岩石中铅、硫、氧同位素组成研究，查明青龙村群为金的矿源层。青龙村群经过华里西期岩浆重熔作用、燕山期岩浆热液作用及大气降水混合流体的作用，形成了斑岩型、夕卡岩型、热液型多金属矿床。对小西南岔金、铜矿床同位素地球化学的分析，为追朔矿源提供了极其重要的同位素地质依据。 |

| Abstract: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. |
