摘　　要：华北克拉通北部内、外缘中生代形成的有色金属矿种繁多 ,以外缘富 Sn、内缘富 Mo,Cu、Pb、 Zn遍布内、外缘为主要特色。通过内、外缘典型矿床的研究和综合对比 ,认为外缘的富 Sn是与富 Sn的基底有关 ,内缘的富 Mo是与结晶基底地层和岩浆热液关系密切。而内、外缘 Cu、 Pb、 Zn的成矿与中生代构造转折 。The north part of North China craton is abundant in non ferrous metal resources,richin Sn in the external margin,Mo in the internal margin,and Cu Pb Zn throughout the whole margin.Based on the study and comparison of the typical deposits in the external and internal margin,it is proposed that Sn enriched in the external margin is related to the Sn-enriching basement and the Mo enrichment to basement and magmatic hydrothermal solution.Cu-Pb-Zn metallogenesis is related to the massive volcanic activities and metals unloading from the metallogic fluid caused by tectonic transform in Mesozoic.
