Sedimentology, cyclostratigraphy and sequence stratigraphy of the Tü / rbeyani
Marls (Albian) and the inpiri Limestone (Upper Barremian-Albian) members of Ulus
Formation (incigez, Bartin, Amasra) were interpreted in this study.
In the Tü / rbeyani Marls total of five different facies were defined. Marl and
limestone facies are the most abundant in the succession. The depositional
environment of the succession was defined as an outer shelf area. Within the pelagic
marls 39 smaller order and 9 higher order cycles were recognized. These cycles
correspond to the parasequences and parasequence sets of sequence stratigraphy,
respectively. In the measured section only one type-3 sequence boundary was
identified.
In the inpiri Limestones great variety of limestone facies are represented.
Bioclastic, peloidal, intraclastic wackestone-packstone-grainstone facies are the most
abundant. Moreover, occurrence of lime mudstone, fenestral limestone, ooid
packstone-grainstone, and sandstone facies are present as well. In the measured
section of the inpiri Limestones 25 fifth order and 6 fourth order cycles were defined.
These cycles correspond to the parasequence sets and systems tracts of the sequence
stratigraphy, respectively. Total of three transgressive and three highstand systems
tract were defined. Only one type 2 sequence boundary was identified in the measured
section, the rest of them are interrupted by covers.
This study revealed that the Tü / rbeyani Marls and the inpiri Limestones are not
economically valuable as petroleum source and reservoir rocks, respectively. The total
organic carbon (TOC) values of marl facies of the Tü / rbeyani marls are very low, and
the pore spaces observed in the inpiri Limestone are cement filled making it
unsuitable reservoir rock.
