Summary:The Sol Hamed complex comprises ultramafic rocks, gabbros, sheeted dykes and pillow lavas and is an obducted, tilted ophiolite. It is unconformably overlain by the Nafirdeib series (712 + or - 58 m.y.) - a volcaniclastic series of conglomerates, olistostromes, felsitic and dacitic tuffs, turbidites, black shales and andesites; NE-SW folds and cleavage postdate the deposition of the series. Granite (approx 669 m.y.) intrudes the ophiolite and the Nafirdeib series. Averaged analyses (major and trace elements) are given for several basalts, andesites and dacites from different parts of the Nafirdeib series. The ophiolite is thought to occur on a suture, with the series representing part of an island-arc sequence. [A.C.B.]
