| 中文摘要: |
| 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。 |
| 英文摘要: |
| 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 distribution of the above horizons, their lithology, typical deposits and summarize the geological characteristics that control the ore. |
