作者通过对冀西北金、银多金属矿化集中区成矿规律和物探航磁、重力及遥感信息的综合研究，提出冀西北地区存在一个超越内蒙地轴与燕山褶皱带两个不同历史大地构造单元之上的中生代地幔热柱构造。文中例举了地幔热柱构造标志特征，探讨了地幔热柱构造地质作用（超变质作用、岩浆作用、成矿作用）及其时空演化规律，建立了地幔热柱构造的壳幔成矿模式 Based on the study of the metallogenic regularity and geomagnetic, gravity and remote sensing information of the gold and silver-polymetallic mineralized area in the northwestern Hebei Province, the authors propose that there exist two structural units that are different from the Inner Mongolia and Yanshan fold belts in northwestern Hebei Province Above the Mesozoic mantle plume structure. The characteristics of mantle plume structures are illustrated in this paper. The geological and tectonic processes of the hot mantle plumes (metamorphism, magmatism, mineralization) and their temporal and spatial evolution are discussed. The crust-mantle metallogenic model
