| Abstract: | The fluid inclusions within the quartz samples from several hydrothermal mineral deposits were dated with the 40 Ar 39 Ar technique by crushing i n vacuum. The deposits included:1) one tin tungsten deposit;2)three gold depo sits and 3) one copper deposit. The isochron ages were agreeable with the geolo gic background data respectively. The major points and some experiences for dati ng the fluid inclusions by crushing in vacuum should be summarized now. In this paper, the crushing apparatus, experiment procedure and applications of 4 0 Ar 39 Ar technique are introduced in detail. The possible causes for t he samples failed to obtain reasonable ages are discussed and the unsuitable min erals dated by this technique are summarized. |
