Description
Summary:Gabal Abu Had represents one of the widely distributed localities of the Late Precambrian Dokhan Volcanics in Egypt. The Abu Had volcanics are characterized by predominance of pyroclastics similar in that character to modern volcanic arcs. Chemically, they belong to the calc-alkaline series which characterize volcanism in island-arcs and continental margins. Ah island-arc1 environment is suggested for the Dokhan volcanics of Gebel Abu Had based on major and immobile trace elements.
