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 Neotethys. The Keven block includes mainly slope deposits (poorly-sorted carbonate breccia and fossiliferous calcarenite) and dated as late Asselian-Sakmarian, whereas the Cingeypinari block consists of platform deposits (fossiliferous platform carbonate and quartz sandstone alternation) assigned to the Sakmarian-early Artinskian. These Early Permian Cingeypinari and Keven blocks from the Beysehir-Hoyran Nappes are biostratigraphically well correlated to the northerly originated Hadim nappe and its equivalents in the Tauride Belt. Considering recent studies on the Mersin Melange, a possible mantle plume existed during the Late Carboniferous-Early Permian time interval along the northern Gondwanan margin. This event led to the opening of the northern Neotethys and deposition of the pelagic "Karincali" sequence with volcanic material in the basinal conditions. The data presented suggest that the Keven block relates to the slope and the Cingeypinari block to platform conditions deposited as a lateral equivalent of the Karincali sequences during the Early Permian.

Tectono-metamorphic evolution of the northern Menderes Massif : Evidence from the horst between Gördes and Demirci Basins (west Anatolia, Turkey)
Buğdaycıoğlu, Çağrı; Bozkurt, Erdin; Department of Geological Engineering (2004)
The Menderes Massif forms a large metamorphic culmination in western Turkey ا an extensional province where continental lithosphere has been stretching following Palaeogene crustal thickening. Northern sector of the Massif on the horst between Gördes and Demirci Basins was chosen for structural analysis aimed to study the tectono-metamorphic evolution of the northern Menderes Massif. Within the study area, four groups of rocks are recognized: (1) the metamorphic rocks ا orthogneisses and metasediments; (2) ...
An example of an accretionary fore-arc basın from Northern Central Anatolia and its implicaiıons for the history of subduction of neo-tethys in Turkey
KOCYIGIT, A (1991-01-01)
Deformed sedimentary sequences of Late Cretaceous-middle Eocene age located between the Sakarya continent and the Anatolian Complex have been interpreted as the fill of a forearc basin. The history and structure of this basin are critical for understanding the evolution of the Neo-Tethyan subduction in the Middle East. I test and elaborate upon this interpretation on the basis of three basic outcrop areas of Upper Cretaceous-lower Tertiary sedimentary sequences confined to a northeast-southwest-trending b...
Geodynamic significance of the Cretaceous pillow basalts from North Anatolian Ophiolitic Melange Belt (Central Anatolia, Turkey): geochemical and paleontological constraints
Rojay, Fuat Bora; Altiner, SO; Onen, AP; James, S; Thirlwall, MF (2004-09-01)
The most widespread blocks within the Cretaceous ophiolitic melange (North Anatolian ophiolitic melange) in Central Anatolia (Turkey) are pillow basalts, radiolarites, other ophiolitic fragments and Jurassic-Cretaceous carbonate blocks. The pillow basalts crop out as discrete blocks in close relation to radiolarites and ophiolitic units in Cretaceous ophiolitic melange. The geochemical results suggest that analyzed pillow basalts are within-plate ocean island alkali basalts. The enrichment of incompatible ...
New evidence of Middle Triassic (late Anisian to late Ladinian) radiolarians from blocks of pelagic volcanosedimentary successions in the Mersin Mélange, southern Turkey: Implications for the evolution of Neotethyan Izmir-Ankara-Ocean
Tekin, Uğur Kağan; Bedi, Yavuz; Okuyucu, Cengiz; Göncüoğlu, Mehmet Cemal; Sayıt, Kaan (2017-10-29)
The Mersin Mélange (MM) as a part of the Mersin Ophiolitic Complex is a sedimentary complex including blocks and tectonic slices of oceanic litosphere and continental crust of various sizes. MM is mainly located to the north and northwest of city of Mersin in southern Turkey. Based on studies on four stratigraphic sections (the Cakalkayrak, the Aliclipinar-Southwest, the Sorgun-South and the Kocatepe-South) from either blocks or tectonic slices in MM reveals the presence of succ...
Integrated Radiolaria, benthic foraminifera and conodont biochronology of the pelagic Permian blocks/tectonic slices and geochemistry of associated volcanic rocks from the Mersin Melange, southern Turkey: Implications for the Permian evolution of the northern Neotethys
TEKİN, UĞUR KAĞAN; OKUYUCU, CENGİZ; Sayıt, Kaan; Bedi, Yavuz; Noble, Paula J.; Krystyn, Leopold; Göncüoğlu, Mehmet Cemal (2019-03-01)
Blocks and tectonic slices within the Mersin Melange (southern Turkey), which are of Northern Neotethyan origin (Izmir-Ankara-Erzincan Ocean (IAE)), were studied in detail by using radiolarian, conodont, and foraminiferal assemblages on six different stratigraphic sections with well-preserved Permian succesions. The basal part of the Permian sequence, composed of alternating chert and mudstone with basic volcanics, is assigned to the late Asselian (Early Permian) based on radiolarians. The next basaltic int...
