Sedimentological And Cyclostratigraphic Analysis Of Upper Part Of The Kartal Formation (sw Of Ankara)

The Montian Kartal Formation lies in the south-west of Ankara region and
overlies the Upper Cretaceous Beyobasi Formation and is overlain by Thanetian
Kirkkavak Formation conformably in the studied region (Kayabasi village, NW of
town of Haymana). A 283 m stratigraphic section, which is mainly composed of
an alternation siliciclastic and carbonate rocks has been measured in the Kartal
Formation within the Haymana-Polatli basin.
The aim of this study is to carry out the sedimentological and
cyclostratigraphical analyses of the upper part of the Kartal Formation within
Haymana-Polatli basin which represents a well developed cyclic pattern. In this
study, detailed lithofacies analyses were performed and four different facies were
recognized along the measured section: sandstones, limestones, mudrocks and
conglomerates.
Sedimentological analyses, such as modal, provenance, palaeocurrent,
grain-size and grain parameters were also performed and their relation with the
depositional environment and change in depositional conditions were discussed.
Interpretations of the depositional environment revealed that the deposition
occurred by low sinuosity rivers and waves. Additional environmental
interpretations suggested that the sediments were deposited in shallow marine
and/or coastal (beach) environments. High resolution cyclostratigraphy studies
based on meter scale cyclic and rhytmic occurrences of lithofacies along the measured section were performed. The whole section, which is 283 m thick, was
divided into large-scale hierarchy-cycles which comprise smaller-scale fining
upward and deepening upward cyclic and rhythmic beds.
