摘要: 江南造山带中段幕阜山地区发育规模巨大的早白垩世Li-Be-Cs-Nb-Ta等稀有金属和Pb-Zn-Cu-Au-Sb等有色金属岩浆-热液成矿系统。幕阜山岩体南、北缘的湘东北和鄂南地区具有相同的成矿物质基础，但现有矿产勘探成果差距明显，可能是构造变形差异所致。本文通过构造解析、古应力场反演以及矿床分布特征，探讨了鄂南地区的构造控矿作用。构造解析表明E-W走向江南断裂形成于新元古代，保存了三叠纪由S向N的逆冲作用、晚白垩世断层上盘向SE的正断作用和古近纪E-W走向左行剪切作用；而NE-Abstract: [Objective] An intensive Early Cretaceous magmatic-hydrothermal metallogenic system occurred in the Mufushan area, central Jingnan Orogen. The Jingnan Orogen in the South China Block resulted from the accretion and subsequent collision of the Yangtze and Cathaysia blocks during the Early Neoproterozoic, consisting of Li-Be-Cs-Nb-Ta rare metal deposits and Pb-Zn-Cu-Au-Sb nonferrous metal deposits. The northeast Hunan Province and the south Hubei Province are located to the
