摘　　要：湘南为我国著名的有色金属成矿区,近年来相继发现了一批红土型金矿床(点)。通过对区内喜马拉雅构造运动阶段地壳运动、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,认为该阶段的新构造运动期为湘南红土型金矿的主成矿期。矿床受区内基底断裂控制,呈带分布。而红土型金矿具有风化壳剖面厚度小、成熟度偏低、对矿源体类型及含金性依赖强、含矿层单一且厚度较小的特点。Southern Hunan province is a famous metallogenic area of nonferrous metals. Some laterite gold deposits have been discovered in this area. Through studies on the crustal movement in Himalayan orogenic period, paleoclimate change, types and contribution of source bodies, the geologic characteristic of the laterite gold deposit, it is believed that neotectonic period was the main mineralizing epoch for the laterite gold deposits in southern Hunan. The laterite gold deposits are controlled by the EW basement faults and distributed in belts. The laterite gold deposits show some characteristics such as small thickness in weathered section, the lower maturity, higher dependence on the gold-bearing property and the source body types, single gold-bearing bed with smaller thickness.
