Rare-earth elements in some Egyptian metavolcanics
Abstract Ten samples from Egyptian metavolcanic formations (Qena-Quseir area, central Eastern Desert) have been analyzed for rare-earth elements (REE). The studied rock types include metabasalt, metaandesite and metadacite. On the basis of REE data, it is suggested that these volcanic rocks represent at least two magma types, a tholeiitic and a calc-alkaline magma.
