| 摘 要： | 在分析阿尔泰山地质演化历史的基础上．讨论了相关地质体为该区砂金矿提供物源的可能性。指出从石炭纪到二叠纪。广泛发育的原生金矿床构成了该造山带金的专属成矿域。所以原生金矿是砂金最主要的物源。新生代，阿尔泰山在喜马拉雅运动影响下，发生差异性升降和遭受非均一性剥蚀．导致砂金矿在空间分布上和原生金矿成反消长关系。在砂金成矿过程中，氧化还原反应起着积极作用。

| Abstract: | Based on the analysis on the geologic evolution history of the Altay Mountains, this paper discusses the possibility of providing metals by relative geologic bodies of gold placers in the mountainous areas. It is pointed out that the extensive development of primary gold deposits from the Carboniferous Period to the Permian Period structured the gold-metallogenetic provinces of the Altay orogenic zone, so the primary gold deposits are the principal mineral origins for the placers. Under the effects of the Himalayan orogeny in the Cenozoic Era, the different elevation and subsidence movement and the heterogeneous denudation occurred in the Altay Mountains, thus, the spatial distribution of placer gold deposits is opposite to that of the primary gold deposits. In the metallogenetic process of gold placers, oxidation-reduction played an important role. |
