摘要
对新疆苏木达依日列克河砂金矿的研究发现，山区冲积型砂金的粒径一般较小，成色较高，表面具明显机械搬运的痕迹，如撞坑、擦痕等。伴生矿物是砂金成因和富集规律的重要指示标志。本文还注意了冲积型和残坡积型砂金矿中砂金理化特征的区别。
Based on the research of the placer gold in Sumudayirilieke River ,this article finds that the grain size of alluvial placer gold in mountain areas is small,and the purity is high.The surface of placer gold is marked by mechanical transportation.The associated minerals are the important indicator of the genesis and enrichment of placer gold .The article also discusses the difference of physicochemical characteristics between placer gold of alluvial mine and eluvial slope wash placer mine.
