Tracing ancient continental crust beneath juvenile oceanic arc in northern Arabian-Nubian Shield,Egypt

李献华  Yasser Abd El-Rahman  
【摘要】:正The intra-oceanic arc(IOA)is generated by partial melting of mantle wedge where one oceanic plate subducts beneath another,contamination of the ascending IOA magmas by continental crustal materials is eliminated.Thus,accretion of IOAs to the continents results in a"net growth"of continental crust.This classic viewpoint appears to be
