摘要
对滇黔桂区中三叠世安尼期浊积岩微相的划分,认为区内浊流有3处发源地,形成了3个浊积扇,每一扇中又由中心相、过渡相及末梢相组成,从各微相分布特征和含金性分析,认为浊积岩的过渡相与卡林型金矿密切,并提出了找矿方向.
Based on the divison of the microfacies of the Middle Triassic Anisian turbidite in the Triangle area of Yunnan,Guizhou and Guangxi Province,it is suggested that there are three source region of turbidity current in this region,and formed three turbidite fans,each of which is consisted of central facies, transitional facies and terminal facies. According to the distribution characteristics and Au-bearing property of the microfacies,it is believed that the transitional facies of turbidite is closely associated with the carlin-type gold deposit,and the prospect of gold ores is proposed.
