| Abstract: | The artificial placer quartz in auriferous quartz veins from Pingjiang to Liuyang of Hunan Province was dated using the fission track technique. The method of chemical etching on quartz has been improved, and 65% NaOH solution was selected as the etching reagent, achieving quite good results.The fission track age of the studied quartz samples is 100-160 Ma. The uranium concentration and microdistribution of the auriferous quartz veins from somewhere of Xinjiang were also analyzed in this study. |
