In the context of this work, it was determine the best region to
invest, It is in the north of the valley Zkarh around the wells 7, 8 and
13, where the thickness of the clay level is large and thickness of
sedimentary cover overlying is few. The r
esults of the chemical
analysis of clay samples in the studied area, the abundance of oxides
of silicon and aluminum oxides in the mineral composition of clays
Which refers to the composition of argillaceous minerals component
mainly of Ilites in the most area and of montmorillonite in the
center of the area near the wells 15, 16 and 17 sites.
The clay was deposited in the study region from erosion of varying
composition rocks, as weathering of Lower Eocene chalky rocks
containing a cherty levels and weathering Cretaceous and
Paleogene carbonate deployed in the north of the Zkarh valley. The
chemical composition of clay of Zkarh Valley is typical for use in
the ceramic industry.
Tripoli in the studied area is a porous, friable and lightweight siliceous
sedimentary rock composed mainly of microcrystalline quartz, and were found
to be resulting from silicification of limestone, and consists of microcrystalline
quartz and im
purities of calcite and halite; the silica ratio ranged between
63.01 – 96.75 % .
