摘　　要：对区内喜马拉雅期地壳运动、古气候变化特点、矿源体类型及分布、红土型金矿床地质特征等方面的研究 ,认为新构造期为湘南红土型金矿的主成矿期。矿床受基底断裂控制 ,呈带状分布。红土型金矿具有风化剖面厚度小、成熟度偏低、对矿源体类型及含Au性依赖强、含矿层单一且厚度较小的特点。The studies on the crustal movement in Himalayan orogeny period,changes of paleoclimate weather,types and distribution of sourcebodys,the geological characteristics of the lateritic gold deposit,show that neotectonic period was the dominant epoch of mineralization of the lateritic gold deposits in southern Hunan.The deposits are controlled by foundation faults,distributed in belts.The lateritic gold deposits have characteristics of small thickness in weathered section, lower maturity,higher dependence on the gold bearing property and the source body types,singal gold bearing bed of smaller thickness.Secondary enrichment of gold in the lateritic gold deposit is closely correlated to oxidization of pyrite and absorption of limonites
