In the former province, the upper mantle rocks consist of harzburgite and lherzolite, characterized by the concentration of mantle type elements (K T) and the smooth-weak enrichment type REE patterns; the ocean volcanic rocks are dominated by basic rocks of subalkaline and oceanic ridge type; lead isotopes are noted for 206Pb/ 204Pb<18.
前者上地幔岩有方辉橄榄岩和二辉橄榄岩 ,幔型元素 (KT)富集 ,REE呈平坦—弱富集型 ;大洋火山岩以基性岩、亚碱性、洋脊型为主 ;铅同位素2 0 6 Pb/2 0 4 Pb <18。
