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。
Endogenous phosphate rock (mainly magmatic rock type deposit) occupies an important position in the world phosphate rock resources. Among the three major endogenous phosphate rocks in the world, the most favorable metallogenic model is the ultrabasic alkaline carbonate rock complex type phosphate rock, which is activated on the edge of the old platform or on the platform, and controlled by deep and large faults. More than 40 alkaline complexes have been found in our country, mainly distributed in North China and Tarim platforms. Looking forward to the north, the prospect of finding phosphorus is optimistic. The prediction of magmatic rock type phosphate rock should be grasped according to the metallogenic regularity, the distribution law of complex rock mass and the deposit characteristics.
