摘要
Nb-enriched arc basalts,an extremely special rock type,were formed in a specific tectonic setting,which have attracted much attention in recent years.Although Nbenriched basalts in the Yining Block were interpreted as arc-affinity basalts,some geologists suggested that they should be Nb-enriched continental basalts and not arcrelated.Recently,the Nb-enriched arc basalts have been first identified from the Dahalajunshan Formation in southern Wusunshan,Yining.
