Ml. Meleik et al., INTERPRETATION OF AIRBORNE RADIOMETRIC AND MAGNETIC DATA IN THE WADI-MILLAHA AREA, NORTH EASTERN DESERT, EGYPT, Discovery and innovation, 10(1-2), 1998, pp. 65-74
Wadi Millaha area is located in the North Eastern Desert of Egypt. It
has been systematically surveyed using airborne gamma-ray spectrometri
c and magnetic methods. In the present study, the identification of bo
th uranium and thorium anomalies has been mainly based on examining a
set of composite spectrometric profiles over eight radiometric anomali
es. The studies revealed the presence of two high radiometric anomalie
s while the rest are moderate to weak ones. The fault systems in the a
rea under study play an important role in the distribution of most of
the identified radioactive anomalies. Two sets oriented ENE to NE and
NNW proved to have a significant effect on of the majority of these ra
diometric anomalies. The structural interpretation of aeromagnetic dat
a of the area under consideration was delineated. Moreover the qualita
tive interpretation for the magnetic anomalies about the main structur
al and lithologic manifestation is accomplished. Filtering of the anom
alies was done to assist in discriminating shallow and deep ones. Appl
ication of trend analysis for aeromagnetic and aeroradiometric data co
uld show the dominant subsurface structures in the N-S trend, while th
at of the surfaces is in the NW-SE trend.
