Other Abstract拉拉铜矿区赋矿层位变质沉积岩的主量元素(ICV(av)=3.04,K2O/Al2O3(av)=0.22,CIA(av)=53.1)及Cs、Rb显著亏损特征,表明其物源区岩石只含有较少的粘土矿物和碱性长石,为中—低化学风化程度,且处于较不稳定的构造环境;多数样品的微量元素表现为显著富集高场强元素、亏损过渡族元素及Cr/Zr(av)=0.15、Th/Sc(av)=0.58,且具轻稀土富集、重稀土平坦((La/Yb)n(av)=25.7)的稀土元素配分模式,表明物源区以长英质组分为主;Sm、Nd同位素组成特征也显示其物源区以长英质组分为主,且沉积于大陆岛弧的弧后拉张环境。同时,结合矿区赋矿层位变钠质火山岩的构造判别结果,认为拉拉铜矿床也形成于该构造背景下。
