CONCLUSIONS
In the biostratigraphic and paleoecologic study of the Cretaceous-Tertiary
succession in the studied sections at (Gali, Qulka. Qishlagh, Kato and Sirwan
valley) in Sulaimani area, Kurdistan region, northeast of Iraq, the consecutive
preference deductions manifested as the end result of this effort to apprize the
summit trail which imply the following points:
1- Choosing the optimum method for preparation and separation
foraminiferal test from the rock type of soft, friable, porous, and permeable rock
and used for different lithologic type, e.g (claystone, shale, marl, marly
limestone and limestone.
2- A detailed study includes the well description and high resolution lithologic
constitution and field work investigation carried on the well exposed of the most
upper part of the Upper Cretaceous/Lower Tertiary successions incorporated
the upper part of Tanjero Formation in Sirwan valley, Kato, Qishlagh and Dokan
section included with the lower most part of Kolosh Formation and Red Bed
Series of the Early Tertiary, while in the Gali section (Smaquli area) the studied
stratigraphic units include the Upper part of Shiranish Formation, Shiranish-
Tanjero transition unit (Reddish to pale brown succession), Tanjero Formation
and Kolosh Formation and the fieldwork at different settings is presented
towards a reasonable and meaningful subdivision of the studied sections. In
addition to that, the studied sections included the interfingering of Aqra
Limestone unit, occurred within the upper part of Tanjero Formation in
Qishlagh, Kato and Qulka sections.
3- Due to the great similarities in the lithologic characters between the two
formal units of Tanjero and Kolosh Formations in the field, it is quit difficult for
