Si. Rabie et al., STATISTICAL INTERPRETATION OF AIRBORNE GAMMA-RAY SPECTROMETRIC DATA, ESH-EL-MILAHA AREA, NORTHERN EASTERN-DESERT, EGYPT, Journal of African earth sciences, and the Middle East, 19(1-2), 1994, pp. 117-123
The technique of factor analysis has been applied to airborne gamma-ra
y spectrometric data from the Esh Ei Milaha area, northern Eastern Des
ert, Egypt This analysis allows the geophysicists to perform a co-ordi
nated transformation of the three radioactive element concentrations (
eU, eTh and K%), their ratios and the total count. It is concluded tha
t factor one (F1) has an appreciable high positive loading for variabl
es Th and K and a negative loading for U/Th and U/K ratios. The second
factor (F2) has a high loading for U,U/Th and U/K, while factor three
(F3) has a negative loading with the total count. Factor one (F1) rep
resents the integrated radioactivity, while F2 and F3 allow the differ
entiation of rock types. The calculated factor scores may be used to s
patially characterize different rock units in the Esh El Milaha area,
Eastern Desert, Egypt.
