| Abstract |
The Nile alluvial soils in the northern part of the Delta have been
formed under the active effects of the sea and the brine lakes in the
recent geological period. The clay minerals (in the soil fraction <
0.002 mm) of five soil profiles at different proximities to northern
brine lakes (0-22 km) and the sea (15-39 km) and at varying altitudes
(2-10 m) were identified and their contents were semi quantitatively
determined. In all the samples, an iron-rich smectite mineral assumed
predominance accompanied with varying amounts of kaolinite and in
some cases illite. The distribution of these varying quantities of
kaolinite and illite in the soil showed no presumable relationship to
the setting of the profiles relative to the lakes or the sea nor to their
elevation relative to each other or to the sea level. Results thus
suggested that the Nile suspended matter was nearly the only source
of clay minerals in all the sediments, regardless of their various mode
of origin, either in the Nile Delta or even in the Nile Valley. Reasons
that prevent using clay minerals distribution, in drawing conclusions
about the history of soil formation were listed and discussed.
