Abstract
The Precambrian rocks of Sinai occupy the southern
triangular part of the Peninsula. These rocks include schists,
gneisses, migmatities, mafic-ultramafic rocks, granitoids and
volcanics.
The present study is carried out on the area south of
Taba city, As far as the author is aware, no detailed studies
were carried out before on that area. except scarce studies
by Amit and Eyal (1976) and Eyal (1980). in which the present
work has showed many def ec ts. The presen t Thesi sine 1ud es
detailed geological, structural, petrochemical and geochemical
studies for the different types of metamorphic and igneous
rocks as well as their relation to the Egyptian rock units.
Special emphasis is given to the migmatization processes and

These studies will generally throw light on the geological

especially in Sinai.
It is a strip-like area extending parallel to the Gulf
of Aqaba. between Taba and Nuweibi (Fig. 1.1). The area is
limited by Latitudes 29° 05 and 29° £6 N and around Longitude
