Abstract:

四川省会理菜子园红土型镍矿床中出露较多的基性-超基性岩体,文章系统报道了其中3个橄榄岩体的岩石化学、铂族元素及Re-Os同位素地球化学特征。岩石化学均显示为高MgO及高Mg#值,低SiO2、Al2O3、Na2O、K2O特征,计算显示出主要的标准矿物为橄榄石和紫苏辉石(体积百分数>90%),表明菜子园属镁质方辉橄榄岩。铂族元素总量比世界上大多数地幔橄榄岩低,且Cu/Pd比值大于原始地幔,可能是早期地幔较高部分熔融出的基性岩浆中硫化物的萃取、抽提作用所致。PPGE相对IPGE强烈亏损,与正常蛇绿岩底部的地幔橄榄岩特征类似,向右倾斜的原始地幔标准化配分模式表明菜子园铂族元素体系主要受地幔部分熔融的控制。PPGE中,Pt相对于Pd富集,可能与后期强烈蚀变有关,此外还可能反映了少量Pt以合金形式残留于方辉橄榄岩中,Pd以不相容元素的形式更多被熔体带走。菜子园方辉橄榄岩的Re-Os同位素体系封闭性相对好,γ(Os)值较小。岩石化学、铂族元素及Re-Os同位素地球化学显示,菜子园橄榄岩直接来自地幔,属正常蛇绿岩套底部的方辉橄榄岩,为古小洋盆洋壳的残片。菜子园蛇绿岩反映了中元古代晚期昆阳裂谷在菜子园-踩马水-麻塘断裂带以北演化成小洋盆,于其中沉积会理群,并在中元古代末期与南侧的东川群、汤丹群碰撞、拼贴。菜子园橄榄岩的蛇绿岩属性进一步证明,扬子地台西南缘的基底由不同时代的小陆块碰撞、拼贴导致基底陆壳增生。
