Résumé partiel
Wadi Abu Marawat is located south Safaga, along the Red Sea coast, in the north part of Central Eastern Desert of Egypt. It is accessible by a 42 km to westward along Safaga–Qena asphalt road. Then turn to the south east through desert track, about 26 km. The area under investigations lies between latitudes 26º 29’ 00’’ – 26º 32’ 30’’ N andlongitudes 33º 36’30’’ – 33º 41’00’’ E. It covers an area of about 160 Km2.The study area The study area The study area The study area The study area The study area The study area The study area The study area The study area is bounded by G. Wairah from the north east and Khur Abu Nahas from the south west. Generally the path of this Wadi and their tributaries are controlled by faults and fracture system. This Wadi running from high relief in NE (Upper stream) to low relief in SW (Downstream).The present work deals with study of geology, petrography, geochemistry, mineralogy and radioactivity of the stream sediments and the country rocks of Wadi Abu Marawat. 9.1 Geology and petrography The Precambrian rocks exposed around Wadi Abu Marawat are arranged chronologically from the ol from the ol from the ol from the ol dest to the youngest as follows : dest to the youngest as follows : dest to the youngest as follows : dest to the youngest as follows:dest to the youngest as follows:dest to the youngest as follows : dest to the youngest as follows:dest to the youngest as follows : dest to the youngest as follows : 7.

Wadi Abu Marawat is cut by several structure elements including folds, faults and shear zones. Metavolcanics and the Banded Iron Formation are intensively folded into anticlines and synclines. The axes of these folds trend in N-S direction and plunge steeply to the north.
