RESUMEN
The present paper deals with the overall geochemical characteristics of the Dokhan volcanics in ten selected localities in the Eastern Desert of Egypt and the maturity of the arc magmatism. Dokhan volcanics Comprise mainly basalts, basaltic andesites, andesites, dacites and rhyolites, in addition to their pyroclastic equivalents. The Dokhan volcanics were derived from a Calc-alkaline magma erupted along an active continental margin, the calc-alkaline nature of these rocks is the most pronounced feature of the parent basaltic magma. The resulted volcanic arcs are compared with some modern arcs, e.g. Tonga-South Sandwich, New Zealand and New Guinea. The Dokhan volcanics have active similarity of the mature arcs active continental margin of Chili.,whereas the arc maturity increases towards Esh El-Mellaha range as well as, highly mature volcanic arc similar to that of New Guinea
