Petrography and Synsedimentary Processes of Carbonate beds of Fat’ha Formation. In selected sections at Al-Qayyara area, south of Mosul, Northern Iraq.

Abstract

Fatha was studied in two sections at Alqayyara area southern of Mosul. Petrographically, Sands Fatha indicated composed of quartz monocrystalline and polycrystalline type, while the feldspar forming mostly of plagioclace feldspar and K-feldspar. The rock fragments mostly come of igneous, metamorphic and sedimentary origins. Fat'ha Formation is affected by diagenetic process such as Cementation, Compaction, Neomorphism and Dissolution. limestone beds contain sedimentary structures the effect of environmental factors on shallow environments. The current study showing that the Fatha Formation contains fossils, trace fossils, high percent benthonic foraminifera (Rotallida and Miliolida) and low other fossil such as mollusca.
