摘要
冀北地区分布的金和铅锌银等多金属矿床，成矿地质条件上有相似性，也有差异。金矿主要分布在燕山台褶带内，与早太古代桑干群变质岩系有关，受华力西期水泉沟碱性杂岩体控制。铅锌银等多金属矿主要分布在内蒙地轴范围内，与晚太古代红旗营子群变质岩系有关，受燕山期中酸性浅一超浅成小岩株控制。两者的构造控制相似。
The mineral - formation condition of the gold dePOSits is not only similar to the condition of the Pb-Zn-Ag polymetal ore deposits in the Northern Hebei, but also different to each other. The gold deposits are mainly distributed in the Yanshan platformal fold belt. They relate to the Early-Archeozoic era Sanggan Group metamorphite system, and are also controled by Variscan Shuiquanguo alkaline complex mass, The Pb-Zn-Ag polymetal ore deposits are mainly distributed in The inner Monggol Axis. They relate to the Late - Archeozoic era Honggiyingzi Group metamorphite system, and are also controled by the intermadiate acidity hypabyssal - ultrahypabyssal small stocks during Yanshan movement. Bath gold deposits and Pb -Zn-Ag deposits are similar in the tectonic control.
