摘　　要：沿镇旬盆地周缘分布着一系列的汞锑、铅锌、金等多金属矿产。近年来 ,在泥盆纪地层中发现的铅锌矿明显受碳酸盐台缘生物礁控制。文中确立了麻坪河生物礁相带和十里生物礁相带。同时运用盆地分析方法 ,对镇旬盆地的形态、性质及相带展布进行了初步分析 ,对碳酸盐台缘生物礁与铅锌矿的关系 ,铅锌矿控矿条件及找矿方向进行了探讨。A series of polymetals such as mercury-antimony,lead-zinc and gold ,and etc.,occurred around Zhenxun basin.In recent years,the lead-zinc deposit found in Devonian stratum was strictly controlled by the biogenic reef in the margin of carbonate plateform.It is determined that Mapinghe biogenic reef facies and Shili biogenic reef facies .And then ,the shape ,property and facies zone direction of Zhenxun basin are initially studied by means of basin analysis.Meanwhile ,the relationship between biogenic reef in the margin of carbonate plateform and lead-zinc deposit,ore-controlling conditions and ore-forming prospecting are discussed .
