摘　　要：华北地块北缘和塔里木地块北缘是中国两个巨型成矿带,主要分布有超基性—碱性岩型、超基性—碳酸岩型、碱性岩型、超基性岩型、基性岩型、伟晶岩型、绿岩带型等8种成因类型的磷矿床,磷矿在大地构造上产于古老地台边缘带,受深大断裂控制.容矿岩石为镁铁质—铁质岩系列,矿物的共生组合主要为透辉石+磷灰石+磁铁矿+黑云母.进一步确定出个12个磷矿找矿潜力区.The northern border of North China Block and northern margin of Tarim Basin are two huge ore-forming belts in china,in which there are 8 types genetic classification phosphate rock such as basic-alkaline rock,ultra basic-carbonatite,alkaline rock,ultra basic rock,basic rock,pegmatite,greenstone belts and so on.Phosphate rock in old platform margin of tectonic belt is controlled by deep fracture.The host rock is mafic-ferruginous rocks suite,and the mineral association mainly is diopside＋apatite＋magnetite＋biotite.This paper has further outlined 12 phosphate rock-prospecting potentials.
