This study including recognition ofdifferent minerals in Tigris River sediments
within grain size (ø>.:) andclay minerals in (5.0ø) grain size, The main minerals
that identified are Quartz, Calcite and Feldspare, The clay minerals are illite,
chlorite, kaolinite, palygorskite and montmorilonite, The heavy minerals are biotite,
epidot, hornblend, zircon, rutile and muscovite. The source of these sediments are
igneousand metamorphic rocks which are found in Northern Iraq within Tigris
catchments area, or derived from Fat7ha and Injana formations outcropedin part of
the area, or may be formed by digenesis processes.
The most common trace elements that have been identified which have local effect
are Cd, Zn, Ni, & Cu of higher concentration more than the natural abundant, there
are a local environmental pollutant in the sediments, may be due to the waste water
and heavy industrial remains along the river valley, from the fertilizing industrial processing and heavy remains of oil from Baiji refinery plant. The other
trace elements are Pb, Fe, Cr, Co, Mn, Se& Ag. The major elements Ca, Mg, K &
Na, all of them are of normal concentration in Tigris River sediments. materials,
