The observation under microscope, the analysis of Au. Ag. Cu. Fe. As content by electron probe and the micrograph of gold grains, confirm that placer gold are natural Au-Ag alloys. The structure and chemical compositions of verge and interior of gold grains differ significantly for large grains but little for small grains and those which intergrow with guartz and limonite.

镜下观察、电子探针分析(Au、Ag、Cu、Fe、As含量)及显微照相等研究，证实了砂金是天然Au-Ag合金，其边部与内部的结构、成分具有不均一性，这在中粗粒金中表现尤为明显，而细粒金及带连生体的金常常不具备这一特点。

One source is from the amalgamation process during refining gold and the other source is from the mercury that associated with the gold deposit.

一是部分岩金矿山和淘砂金者使用的混汞法提金工艺释放大量汞到环境中；另一个是与金矿床伴生的汞在采金过程中被活化迁移到环境中。
