A perspective on the geotectonic setting of early Cretaceous adakite-like rocks in the Lower Reaches of Yangtze River and its significance for copper-gold mineralization

  • 长江中下游地区是中国重要的铜资源基地之一。该成矿带广泛发育与Cu-Au成矿作用密切相关的早白垩世火成岩。大多数与成矿有关的中酸性侵入岩具有类似埃达克岩的地球化学特征,即富集Sr而贫HREE(如:Y和Yb);但它们具有负的εNd(t)值和相对富集的Sr同位素初始比值(>0.704.),因此,被称为埃达克质岩。根据岩石化学数据,研究区埃达克质侵入岩多数属于高钾钙碱性系列,部分属于钙碱性系列;而火山岩和A型花岗岩类由于其高钾和富铁特征而属于钾质碱性系列。岩石地球化学资料显示,与成矿作用有关的中酸性埃达克质侵入岩经历了复杂的成岩过程,至少包括在深位岩浆房(>35~40 km深度)的分离结晶和在高位岩浆房内的分离结晶或AFC过程两个阶段。同时不排除有下地壳直接熔融形成的埃达克质熔体参与的可能性。富钾的火山岩则是原生岩浆在深位岩浆房(>40-50 km深度)经镁铁矿物的分离结晶过程演化而来。基于长江中下游地区及其邻区的区域地质构造、早白垩世岩浆岩的岩石化学和地球化学特征和岩浆活动的时空演变特征的综合分析,推测该成矿带在早白垩世早期处于大陆边缘岩浆弧内陆一侧,岩浆活动与古太平洋板块的斜向俯冲作用有关;晚期由于俯冲板片迁移(变陡),岩浆岩具有弧后环境特征。俯冲板片上部所释放的超临界流体提高了地幔
