摘　　要：藕塘湾金矿是鄂南典型红土型金矿,属于风化型金矿床,赋矿层位主要为第四系更新统的红色含砂砾亚黏土,矿体产状平缓,厚度变化较稳定,呈似层状,矿石中金主要以游离状态存在.矿床的成矿控制因素为有利的基底岩层、构造、热液活动及有利于红色黏土生成及保存的气候条件与地貌条件.根据矿区找矿实践经验及其产出的地质背景和矿体特征等提出了找矿的标志.The Outangwan gold deposit,belonging to weathered-type,is a typical laterite gold deposit in Southern Hubei Province.The Quaternary Pleistocene red gravel loam is the main ore-containing horizon.The occurrence of ore body is gentle,with stable thickness.The gold in ore is in free state.The ore-controlling factors include favorable basement rock,structure and hydrothermal activity,as well as the favorable climate and geomorphology for the formation of red clay.The prospecting indicators are proposed on the basis of geological background and characteristics of orebodies.
