摘　　要：安徽北淮阳成矿带中生代岩浆作用强烈,成岩与成矿具有紧密的时空关系和成因联系,广泛发育钼、铅、锌、金等多金属矿化。通过对北淮阳成矿带东段区域基本地质特征、成矿地质作用和成矿规律开展研究,发现该区域上白垩纪早期成矿作用以Au、Ag、Pb、Zn等矿种为主,与之相关的岩浆作用为高钾钙碱和钾玄岩系列的火山岩和侵入岩;而白垩纪晚期的成矿作用以Mo成矿为主,与之相关的岩浆作用主要为碱性深成岩。北淮阳地区进行勘察找矿工作的过程中,应该以白垩纪晚期的(石英)正长岩-花岗斑岩作为重点关注对象。The Mesozoic magmatism is strong in Northern Huaiyang metallogenic belt of Anhui prov⁃ince.There is a close relationship between diagenesis and mineralization in time,space and genesis.Molyb⁃denum,lead,zinc,gold and other polymetallic mineralization are widely developed.Based on the study of the basic geological characteristics,metallogenic geological processes and metallogenic rules in the eastern part of Northern Huaiyang metallogenic belt,it is found that the mineralization of the early Upper Creta⁃ceous in this area is dominated by Au,Ag,Pb,Zn and other minerals,and the related magmatism is the volcanic rocks and intrusive rocks of high potassium calcium alkali and potassium basalt series.The mineral⁃ization of the late Cretaceous is dominated by Mo mineralization,and the related magmatism is mainly alka⁃line pluton.The late Cretaceous(quartz)syenite-granite porphyry should be taken as the focus in the process of prospecting and prospecting in Beihuaiyang area.
