地幔亚热柱-幔枝构造演化及其对金的成矿控矿作用模式OACHSSCD

To elucidate the deep mineralization mechanisms,this study establishes a metallogenic control model within the context of mantle branch structures,systematically analyzing the influence of gold's material sources and migration pathways,tectonic control,and magmatic activity on mineralization.The model clearly illustrates how mantle branch structures form distinct gold deposits in stages and across different types from the Earth's deep to shallow regions,holding significant theoretical value;it also provides guidance for prospecting in favorable areas such as fault zones and magmatic contact zones,facilitating the discovery of deep mineral resources.Furthermore,the mineralization characteristics of silver deposits and polymetallic deposits(copper,lead,zinc)are similar to those of gold,offering insights for studying the metallogenic patterns of other polymetallic deposits.
