The ability to identify the nature of
sedimentation and uraniferous provinces from the air using -ray spectrometry is verified in this work. The
area- investigated, G. ElSerei - G. ElGir, is underlain by a variety of sedimentary rocks,
from alluvial deposits to marine sediments. Thorium and uranium concentration or Th/U
ratio determined from the air suggests that the signatures of these elements serve as
indicator to the nature of sedimentation or environments. The linear relationship between
uranium and thorium is found useful in detecting uraniferous provinces. In other words,
such relationship determines the rock units which are abnormally enriched or depleted in
uranium with respect to the amount of thorium.
