摘要： 阿尔泰山砂金分布同阿尔泰山北西构造带、花岗岩体、含金矿化带、含金蚀变带和基岩等的分布密切相关;并与古风化壳分布一致.到目前为止,虽未发现原生金矿床,但含金地质体分布却较为普遍。由于经过地质时期的长期风化,特别是第三纪的化学风化作用,释放出大量的金元素与金粒,为阿尔泰山砂金提供了丰富的物质来源;表明原生金矿并不是砂金物质的唯一来源。

Abstract: The distribution of Gold Placers in Altai Mts. is related compactly with the location of northwest tectonic belts, granite, containing gold mineralization zones, rock containing gold etc. and is identical with the paleoresiduum existing. No gold Deposit has been found in the mountain region, but mineral containing gold spreads widely. It can release quantity gold element and grains underwent long geologic weathering, especially the chemical weathering during Neotertiary, which supplied gold placers with abundent material source in Altai Mts. It means that gold Deposit is not the only material source of gold Placers.
