Foraminiferal Biostratigraphy

AbstractPlanktonic and benthic foraminifera are described from the Middle Eocene-Lower Miocene successions in the Sivas Basin, Central Anatolia. An integrated foraminiferal zonation provides new age assignments in terms of a great number of taxa for the studied sections. Four biostratigraphical intervals are first recorded based on the concurrent ranges of sporadically occurring but well preserved planktonic foraminiferal assemblages. The first interval characterized by the co-occurrences ofAcarinina bullbrooki, Truncorotaloides topilensisandTurborotalia cerroazulensisis referable to the E11 Zone of late Lutetian–early Bartonian. An assemblage yieldingParagloborotalia opimaaccompanied byGlobigerinella obesaforms a basis for the late Chattian O5 Zone. The successive interval corresponds to the late Chattian O6 Zone indicated by the presence ofGlobigerina ciperoensisandGlobigerinoides primordiusalong with the absence ofParagloborotalia opima. The early Aquitanian M1 Zone can be tentatively defined based mainly on the assemblage ofGlobigerina, Globigerinella, GloboturborotalitaandTenuitella. The biostratigraphical data obtained from the benthic foraminifera assign the studied sections to the SBZ 21–22, SBZ 23 and SBZ 24 ranging in age from Rupelian to Aquitanian. The SBZ 23 and 24 are well constrained biozones by the occurrences ofMiogypsinella complanataandMiogypsina gunteri, respectively, whereas the SBZ 21–22 defined by nummulitids and lepidocylinids in the Tethyan Shallow Benthic Zonation is characterized dominantly by peneroplids, soritids and miliolids in the studied sections. Benthic foraminiferal assemblages suggest different paleoenvironments covering lagoon, algal reef and shallow open marine whereas planktonic foraminifera provides evidence for relatively deep marine settings on the basis of assemblages characterized by a mixture of small-sized simple and more complex morphogroups indicative for intermediate depths of the water column.

The tectonic evolution of Lake Eğirdir, West Turkey Lake Eğirdir is one of the most important fresh-water lakes of Turkey. It has a tectonics-related origin. The area formed under a roughly N-S compressional tectonic regime during the Middle Miocene. The stresses caused slip faults west and east of Isparta Angle, and the lake formed at the junction of these faults. The area subsided between normal faults, thus creating the topographic condition required for a lake. The lacustrine sediments have fundamentally different lithologies. After the Late Miocene, central Anatolia started to move westwards, but western Anatolia moved in a SW direction along the South-western Anatolian Fault, which we suggest to have a left lateral slip, which caused that the Hoyran Basin moved t7 km towards the SW and rotated 40° counterclockwise relative to Lake Eğirdir.
