ABSTRACT
Four sites were sampled during Nov. 1984, in order to
measure the clay mineral assemblages. These sites, All
Al-Sharki, AlMajer, A1-Mes’heb and Shaft Al-Arab, are
distributed along the Tigris river and around Qarmat
All, south of Iraq. The clay mineral assemblages are;
chlorite, illite, kaolinite with traces of illite-chlorite
mixed layer and a notable quantity of amorphous silica.
Chlorite is high in Al-Sharki and Al-Mas’heb sites.
There is a tendency of increasing in percentage of
illite toward the Shaft Al-Arab river. The kaolinite
percentage is relatively stable in the studied sites.
The Tigris and Shaft Al-Arab rivers are lack of smectite.
The amorphous silica is abundant in Al-Mas’heb site. The
clay mineral assemblages prove the origin of the recent
sediments which, originated from the formations, that
outcropped in catchment area of Tigris and Euphrates
rivers.
