GEOLOGICAL STUDIES OF THE PLIO-PLEISTOCENE PALEOSOL SEDIMENTS OF 6TH OCTOBER CITY, GIZA, EGYPT

Eight sections were measured and described from the 6th of October City. These sections are I, II, III,
IV, V, VI, VII and VIII. Lithostratigraphic sections I to III belong to the post- Miocene (Plio-Pleistocene)
paleosols, whereas section V and VI belong to late Pleistocene (most –recent paleosol) and section VIII
belong to Miocene clastic. The sequence of the previously diagenetic processes may be accepted because
the studied paleosols constitute the upper most parts of the stratigraphic sections. So, they did not
subjected to burial compaction and then the cementation played the main role of lithification. Also, the
abundance of iron oxides in the studied paleosol samples may be referred to the Oligocene iron rich
sediments which supply the solutions with more iron oxides. The studied sediments were transported and
deposited mainly by fluviatile processes. These paleosols are resulted from the karstifications processes in
which the dissolution of the Eocene, Miocene and Pliocene carbonates during the pluvial period in an
oxidizing wet phase environments.
