Geochemistry of lamprophyre dykes, Wadi Sikait area, South Eastern Desert, Egypt

摘要

The Wadi Sikait area lies at about 95 km southwest of Marsa Alam City along the Red Sea Coast, Eastern Desert, Egypt. It is occupied by Precambrian rocks of ophiolitic mélange, metamorphosed sandstones (MSS), gabbros and monzogranites which were later intruded by lamprophyre dykes and quartz veins.
