The High Mountains Saint Katherine St . - South Sinai, Egypt

Dykes can be seen in great numbers and in a variety of sizes throughout the South Sinai massif. The typical structure of a dyke is either a gully with vertical walls and fractured base, if its erosion is more intense than in the hosting rock, or an outcrop, if its erosion is lower than in the hosting rock.Geochemistry and petrogenesis of dyke swarms in NW Sinai .

The mafic dykes in Wadi Mandar-Wadi Um Adawi area are as follows: 1 calc-alkaline lamprophyre i.e., kersantite and spessartite , 2 diabase, and 3 alkaline lamprophyre i.e., camptonite . The field relations reveal that the emplacement of calc-alkaline lamprophyres preceded the diabase dykes, while alkaline lamprophyres emplaced later than the diabase dykes. Calc-alkaline are basaltic .
