摘　　要：对华北地台北缘的地球物理场特征进行了探讨 ,根据重、磁异常数据反演计算了该地区的莫霍界面、居里界面、磁性界面的起伏 .利用地球物理场资料和反演计算结果对该地区的构造格架和断裂进行了推断 ,同时预测了 9个成矿远景区 :(1 )集宁—呼和浩特金成矿区 ;(2 )张家口—赤城金、银多金属成矿区 ;(3 )密云—高岭金、铜成矿区 ;(4)青龙—马兰庄金成矿区 ;(5 )秦皇岛、金多金属成矿区 ;(6 )郝家营多金属成矿区 ;(7)承德地区金、多金属成矿区 ;(8)赤峰—喀喇沁旗金成矿区 ;(9)宁城东金、多金属成矿区 .The characters of geophysical fields of the north edge of Huabei platform were discussed. Moho interface, magnetic upper and lower interfaces were calculated for the area using gravitational and magnetic abnormly data. According to the geophysical data and the obtained results, we obtained constructure framework and rupture system of the area. Nine prospect regions for metal ore were indicated. They are: (1) Jining—Huhehaote gold mine area, (2) Zhangjiakou—Chicheng gold and silver multimetal mine area, (3) Miyun—Gaoling gold and copper mine area, (4) Qinglong—Malanzhuang gold mine area, (5) Qinhuangdao gold and multimetal mine area, (6) Haojiaying multimetal mine area, (7) Chengde gold and multimetal mine area, (8) Chifeng—Kelaqinqi gold mine area, and (9) Eastern of Ningcheng gold and multimetal mine area.
