摘　　要：滇东磷矿赋矿层位多样,已发现那章组、梅树村组、筇竹寺组、汤池组、红石崖组或湄潭组、牛滚凼组、海口组、东岗岭组、榴江组、法郎组等10个含磷层位。其中,下寒武统梅树村组及中泥盆统东岗岭组工业价值最大,法郎组是最新发现的含磷层位,并在丘北县舍龙村发现了工业矿体。文章简要介绍了上述各含磷层位的分布、岩性特征及代表性矿床,总结了滇东磷矿的控矿地质特征及成矿规律。There are 10 phosphorite horizons in total in east Yunnan, such as= Nazhang, Meishucun, Qiongzhusi, Tangchi, Hongshiya （or Meitan）, Niuguandang, Haikou , Donggangling, Liujiang, Falang formation. Among them, Meishucun formation of Lower Cambrian and Donglinggang formation of Middle Devonian are the most economical horizon. Falang formation is a newly discovered phosphorite horizon at which we found industrial ore bodies at Shelong village, Qiubei County. This paper briefly introduces dis- tribution of the above horizons, their lithology, typical deposits and summarize the geological characteris- tics that control the ore.
