气相对金属的搬运早在1644年就被人们注意到了,但是长期以来由于对金属气相迁移能力的认识不足和技术手段等原因,这方面的研究工作还很薄弱。对近些年来金属元素在气相中迁移的实验研究及其地质证据等方面的工作概况进行了论述,认为金属的气相迁移是由于金属和气体溶剂间发生反应,形成金属(氯化物)水合物,增大了金属在气相中的溶解度,而并不完全取决于金属元素的挥发性。这一认识对研究元素的气相迁移,尤其是挥发性相对弱的金属元素在气相中的活动行为十分重要。随着研究的深入与基础数据的积累,元素在气相中的迁移及其对金属成矿的重要作用必将引起人们的足够重视。

 The idea that vapor phase can transport metals was mentioned in 1644, but the research is very weak because of the lack of enough recognition and new microanalysis techniques and so on. In this paper, we review some recent experimental study and geologic evidence on the vapor transport of ore metals. It should be pointed out that vapor transport of ore metals relies on the interactions between metals and gas-solvent forming (chloride) hydrate of metals that enhance the solubility of metals in vapor phase, not totally due to the volatility of metals. So it is very important to continue the study of vapor transport of ore metals, especially weakly volatile elements. With the further study and the accumulation of base data, more attention will be paid to the important role of vapor transport of ore metals on the formation of ore deposits.
