| 摘 要： | 内生磷矿（主要是岩浆岩型矿床）在世界磷矿资源中占据重要地位。世界三大内生磷矿中，最佳成矿模式为在古老地台边缘或地台活化带，受深大断裂控制的超基性 碱性 碳酸岩杂岩体型磷矿。我国已发现４０多处碱性杂岩，主要分布在华北地台和塔里木地台，展望北方找磷前景乐观。对岩浆岩型磷矿的预测应按其成矿规律、杂岩体分布规律及矿床特征加以把握。

| Abstract: | The Badawan barite deposit in Ninglang region,Yunnan has a close genetic link with the increased tectonic and magmatic activities during Himalayan orogeny which reworked it,compositionally and structurally,to reach further enrichment.The NNW trending tectonic system in the study area standed for the first order,ore controlling structure to dictate the morphology,occurrence and distribution of the reworked orebodies.Also,the lithology,breakage and geochemistry factors of the primary sedimentary rocks contributed much to the deposits formation.There is a distinct 3 D zonation of mineralization in the deposit. |
