Abstract:

湖北省钟祥市华山观环斑花岗岩是在扬子地块上发现的第一例元古宙环斑花岗岩体.野外观察和岩相学研究表明,华山观岩体北部发育典型的环斑结构,钾长石核呈卵球形,且多数具斜长石环边,碱性长石和石英分为两期甚至多期.样品的主量元素富硅、碱(尤其富钾)和铁,贫钙、镁.微量元素富Th,U,La,Ga,Ce和Sm,贫Sr,Nb和Y;轻稀土富集,重稀土亏损,具铕负异常,并显示A型花岗岩的地球化学特征.采用LA-ICP-MS锆石U-Pb法获得的207Pb/206Pb加权平均年龄为(1851±18)Ma,代表了该环斑花岗岩体的结晶年龄;U-Pb下交点年龄为(803±170)Ma,代表岩体后期可能遭受了新元古代构造热事件改造的时代.扬子地块北缘古元古代环斑花岗岩的发现,表明在1850Ma时扬子地块应处于大陆裂解或造山后伸展的构造环境中,可能与古元古代Columbia超大陆的裂解有关.
