成矿时代问题往往导致对某一矿床成因的认识上争论不休,因此较准确的解决成矿时代问题是十分重要的。 1986年6月,我所同中国有色总公司吉林地矿所合作,经反复探索实验,成功地对吉林省夹皮淘金矿区两个含金的石英样品(见表)进行了Ar~(38)稀释法年龄测定,其结果与地质情况符合。解决了该矿区重大疑难问题。专家们认为石英的Ar~(38)稀释法年龄测定,国内尚
The problem of mineralization age often leads to debate over the genesis of a certain deposit. Therefore, it is very important to solve the problem of mineralization more accurately. In June 1986, after cooperating with Jilin Institute of Geology and Mineral Resources of China Nonferrous Corporation, after repeated exploratory experiments, Ar ~ (38) was successfully carried out on two gold-bearing quartz samples in the Jiapi gold mining area of Jilin Province (see table) Dilution method age determination, the results in line with the geological conditions. Solved the major problems of the mining area. Experts believe that the quartz Ar ~ (38) dilution method for age determination, the domestic Shang
