ABSTRACT: The present work is a petrological
study of the gabbroic rocks of wadi Shianite Southeastern Desert of Egypt.
Chemical analyses for major and trace elements showed that there are 3 main
gabbro types. These are: 1)pyroxene
hornblende gabbronorite;2)
hornblende gabbro;and 3)
anorthosite.The opaque minerals
study of the gabbroic rocks showed that they composed mainly of ilmenite,
magnetite and sulphides. The present gabbroic rocks work are related to
calc-alkaline magma type, similar to the younger gabbros in other areas in the
Eastern Desert.
