摘　　要：蛇屋山红土型金矿体（层）赋存于第四系红土中，矿体呈似层状近水平产出，品位低、规模大、易采易选。矿石松散，组分简单，Ａｕ呈超显微粒状吸附于粘土矿物中。成矿物质来自含矿原岩，成矿作用主要与第四纪中更新世湿热条件下的化学风化作用有关。该矿床是通过检查化探异常发现的，在勘查过程中坚持探采结合，勘查工作指导金矿开发，金矿开发利用又促进矿床勘查，为我国金矿探采一体化工作探索出了重要的经验。The Shewushan lateritic gold deposit is hosted by the Quaternary laterite.The ore body is stratiformlike and nearly flatlying,with low grade,large scape,easy exploitation and extraction.The ore is friable with simply component. Au as submicroscopic particle was absorbed by clay mineral. The oreforming materials originated from orebearing primary rock. The mineralization is mainly related to chemical weathering under the moist and hot condition in the Middle Pleistocene of Quaternary Period.The deposit was found by examing geochemical exploration anomaly. The combination of exploration and exploitation must be upheld. The prospecting work guides the exploitation of gold deposit which promotes the exploration in return. The important experience has been found out for the way of exploration and exploitation merged into an organic whole.
