The Triassic Karakaya Complex (KC) of the Sakarya Composite Terrane in northern Turkey is traditionally subdivided into two units. The Lower Karakaya Complex (LKC) consists of a tectonic m,lange with blocks of metabasic rocks, metacarbonates, meta-arenites and metapelites that have been affected by high pressure/low temperature metamorphism. It is followed by a low pressure/low temperature metamorphic overprint; the latter is the only metamorphic event in some tectonic slivers of the LKC. The Upper Karakaya Complex (UKC) units are primarily composed of diagenetic to low-grade metamorphic rocks, comprising Late Permian and Triassic cherts and blocks of OIB-type volcanic rocks interfingering with Anisian limestones. LKC slide-blocks of variable sizes are frequently observed within the UKC. Phyllosilicates of LKC and UKC were examined for their abundance, crystallinity, polytype and b cell dimension. Trioctahedral chamositic chlorites have IIb polytype and phengites 2 M (1) polytypes in the LKC units and 2 M (1) + 1 M + 1M (d) polytypes of phengitic dioctahedral illites in the UKC units. Kubler index data correspond to the low anchizone and epizone for the LKC units, and to the high diagenesis-low anchizone, and in part to the epizone for the UKC units. The b values of illites are consistent with a high-pressure facies series for the LKC, but only intermediate-pressure facies for the UKC. According to textural features, mineral paragenesis, clay transformations, index minerals, and b values, the lower-middle parts of the LKC represent an accretional tectonic setting, whereas the UKC units reflect pressure temperature conditions of an extensional basin affected by high heat flow.

Tectono-Sedimentary evolution and geochronology of the Middle Miocene Altinapa Basin, and implications for the Late Cenozoic uplift history of the Taurides, southern Turkey
KOÇ, AYTEN; Kaymakcı, Nuretdin; van Hinsbergen, Douwe J. J.; Kuiper, Klaudia F.; Vissers, Reinoud L. M. (2012-04-06)
The Tauride range in southern Turkey is flanked and overlain by Neogene sedimentary basins. To the south and on top of the high range, these basins are mainly marine, whereas poorly studied intramontane basins dominated by continental deposits are exposed to the north. In this paper, we study the stratigraphy and structure of the continental Altinapa Basin, and provide Ar-40/Ar-39 geochronology for volcanic deposits in the stratigraphy. The stratigraphy can be subdivided into a Lower Group, displaying simil...
Uppermost Triassic limestone in the Karakaya Complex - Stratigraphic and tectonic significance
Okay, AI; Altıner, Demir (2004-05-01)
Two important tectonostratigraphic units of the Karakaya Complex in northwest Turkey are: a lower metamorphic sequence of metabasite, phyllite and marble, called the Nilufer Unit; and an upper clastic sequence with Permian and Carboniferous limestone olistoliths called the Hodul Unit. In northwestern Turkey, the Hodul Unit consists of arkosic sandstones, which pass upward into greywacke and siltstone with Permian and Carboniferous limestone blocks. A scarce macrofauna in the sandstones indicates a Norian ag...
Radiolarian biochronology of upper Anisian to upper Ladinian (Middle Triassic) blocks and tectonic slices of volcano-sedimentary successions in the Mersin Melange, southern Turkey: New insights for the evolution of Neotethys
TEKİN, UĞUR KAĞAN; Bedi, Yavuz; OKUYUCU, CENGİZ; Göncüoğlu, Mehmet Cemal; Sayıt, Kaan (2016-12-01)
The Mersin Ophiolitic Complex located in southern Turkey comprises two main structural units; the Mersin Melange, and a well-developed ophiolite succession with its metamorphic sole. The Mersin Melange is a sedimentary complex including blocks and tectonic slices of oceanic litosphere and continental crust in different sizes. Based on different fossil groups (Radiolaria, Conodonta, Foraminifera and Ammonoidea), the age of these blocks ranges from Early Carboniferous to early Late Cretaceous. Detailed fieldw...
Tectono-stratigraphic evolution of the continental miocene basins in Southwest Anatolia
Koç, Ayten; Kaymakcı, Nuretdin; Van Hinsbergen, Douwe J. J.; Department of Geological Engineering (2013)
The Tauride range in southern Turkey is flanked and overlain by Neogene sedimentary basins. To the south and on top of the high range, these basins are mainly marine, whereas poorly studied intra-montane basins dominated by continental deposits are exposed to the north. In this study, the stratigraphy and structure of these continental basins which includes Altınapa, Yalvaç and Ilgın Basins are studied. Their stratigraphy of these basins displays poorly expressed fining upwards sequences of fluvio-lacustrin...
Microfacies analysis of upper devonian - lower carboniferous shallow water carbonates of the Yilanli formation in Zonguldak area, North Western, Turkey
Ahmed, Nouman; Yılmaz, İsmail Ömer; Department of Geological Engineering (2016)
The Yılanlı Formation of Upper Devonian to Lower Carboniferous succession of the Zonguldak region were measured from Gökgöl section near Zonguldak city, NW Turkey. The studied section dominantly consists of limestone of grey – dark grey color with thin to thick beds of black shale and claystone. A variety of lithofacies identified in the studied section including limestone, dolomite, shale, claystone and mudstone. Nine microfacies are identified as grainstone, packstone, wackstone, mudstone, bindstone, ruds...
