The Mersin Melange, a sedimentary complex in southern Turkey, includes blocks of various origins within a Late Cretaceous matrix. Two blocks in the Mersin Melange are herein recognized to be of Carboniferous age. One block (the Kozan Block) is composed of alternating chert and mudstone, and includes radiolarian and conodont assemblages revealing a late Tournaisian (Early Mississippian) age. The other (Keven-West Block) consists of platform carbonate containing abundant foraminifera indicating Bashkirian (Early Pennsylvanian) age. These dates are so far the oldest obtained from the blocks within the Mersin Melange. A correlation of the lithostratigraphies of blocks in the Mersin Melange with the coeval Tauride sequences indicates that they correspond to the successions in the Beysehir-Hoyran Nappes. In these nappes, the late Tournaisian is characterized by radiolarian rich chert and mudstone of an open marine environment, whereas the Bashkirian succession represents a shallow water environment with Foraminifera-bearing limestone. The Tournaisian deepening can be ascribed to the opening of a deep marginal basin to the north of the Tauride Platform and uplifting of the northern Tauride-Anatolide Platform margin during the Late Mississippian and Early Pennsylvanian.

Biostratigraphy of Lower Permian foraminiferal assemblages from platform-slope carbonate blocks within the Mersin Melange, southern Turkey: Paleogeographical implications
Okuyucu, Cengiz; TEKİN, UĞUR KAĞAN; Bedi, Yavuz; Sayıt, Kaan (2020-04-01)
The Mersin Melange (MM) as a part of the Mersin Ophiolitic Complex in southern Turkey is a sedimentary complex including blocks and tectonic slices within a Late Cretaceous matrix. Two blocks (Keven and Cingeypinari) within the MM originated from the northern branch of Neotethys (Izmir-Ankara-Erzincan Ocean) and have been studied in detail using foraminiferal assemblages to correlate them with coeval successions in the Taurides and to approach the Early Permian evolution of the northern branch of the Neotet...
FORAMINIFERAL ASSEMBLAGES AND MICROFACIES ANALYSIS OF UPPER TRIASSIC VOLCANO-SEDIMENTARY SUCCESSIONS IN PALU REGION (ELAZIĞ, TURKEY)
Özdemir, Ayşe; Özdemir, Yavuz; Narin, Azad; Altıner, Sevinç; Oyan, Vural (2019-09-09)
This study focuses on the Upper Triassic recrystallized limestone units alternating with volcanic rocks at southeastern parts of the Elazığ village (eastern Turkey). The Upper Triassic successions are mainly consists of recrystallized limestones particularly rich in benthic foraminifera, megalodonts, and algae. Comprehensive microfacies analysis and faunal assemblages have been commenced throughout the studied sections. The micropaleontological analysis highlights foraminiferal assemblages, d...
Foraminiferal assemblages and microfacies analysis of Upper Triassic volcanosedimentary successions in Plau region (Elazığ, Turkey)
Özdemir, Ayşe; Özdemir, Yavuz; Narin, A; Altıner, Sevinç; Oyan, Vural (null; 2019-09-09)
This study focuses on the Upper Triassic recrystallized limestone units alternating with volcanic rocks at southeastern parts of the Elazığ village (eastern Turkey). The Upper Triassic successions are mainly consists of recrystallized limestones particularly rich in benthic foraminifera, megalodonts, and algae. Comprehensive microfacies analysis and faunal assemblages have been commenced throughout the studied sections.

Foraminiferal biostratigraphy and sequence stratigraphy of peritidal carbonates at the Triassic-Jurassic boundary (Karaburun Peninsula, Western Turkey)
Tunaboylu, B. Coskun; Altıner, Demir; İŞİNTEK, İSMAİL; Demirci, D. (2014-08-15)
Continuous shallow marine carbonates spanning the Triassic-Jurassic boundary are exposed in the Karaburun Peninsula, Western Turkey. The studied section (Tahtaiskele section) consists of Upper Triassic cyclic shallow marine carbonates intercalated with clastics overlain by Lower Liassic carbonates. Based on the microfacies stacking patterns, three main types of shallowing-upward cycles have been recognized. Cycles are mostly composed of subtidal facies at the bottom, intertidal/supratidal facies and/or suba...
Foraminiferal and calpionellid biostratigraphy, microfacies analyses and tectonic implications of the upper jurassic – lower cretaceous carbonate platform to slope successions in sivrihisar region (Eskişehir, NW Turkey)
Atasoy, Serdar Görkem; Altıner, Demir; Department of Geological Engineering (2017)
This study focuses on the biostratigraphy, microfacies analyses and the tectonic interpretation of an Upper Jurassic – Lower Cretaceous carbonate succession widely exposed in a tectonic klippe of the Sakarya Zone (Pontides), north of Sivrihisar region (Eskişehir). For this purpose two stratigraphic sections were measured (925 m thick in total) along the carbonate rocks that crop out north of the Dümrek Village. According to the biozonation and the microfacies types, two coeval but dissimiliar depositional d...
