“…The voluminous early Palaeozoic siliciclastic sedimentary sheet of north‐eastern Africa and Arabia (i.e. Avigad, Kolodner, McWilliams, Persing, & Weissbrod, 2003; Avigad et al., 2015) is correlated, across north Gondwana to the Anatolian Block (Avigad, Abbo, & Gerdes, 2016; Ghienne, Monod, Kozlu, & Dean, 2010; Gürsu et al., 2017), and overall the detrital zircon U–Pb–Hf spectra in the Kyrenia range generally fits that of Palaeozoic rocks from north Gondwana (e.g. Avigad et al., 2003; Kolodner et al., 2006; Meinhold, Morton, & Avigad, 2013; Morag, Avigad, Gerdes, Belousova, & Harlavan, 2011).…”

Drainage response to Arabia–Eurasia collision: Insights from provenance examination of the Cyprian Kythrea flysch (Eastern Mediterranean Basin)

et al. 2020

The Cenozoic geodynamics of the north‐eastern Mediterranean Basin have been dominated by the subduction of the African Plate under Eurasia. A trench‐parallel crustal‐scale thrust system (Misis–Kyrenia Thrust System) dissects the southern margin of the overriding plate and forms the structural grain and surface expression of northern Cyprus. Late Eocene to Miocene flysch of the Kythrea (Değirmenlik) Group is exposed throughout northern Cyprus, both at the hanging‐wall and foot‐wall of the thrust system, permitting access to an extensive Cenozoic sedimentary record of the basin. We report the results of a combined examination of detrital zircon and rutile U–Pb geochronology (572 concordant ages), coupled with Th/U ratios, Hf isotopic data and quantitative assessment of grain morphology of detrital zircon from four formations (5 samples) from the Kythrea flysch. These data provide a line of independent evidence for the existence of two different sediment transportation systems that discharged detritus into the basin between the late Eocene and late Miocene. Unique characteristics of each transport system are defined and a sediment unmixing calculation is demonstrated and explained. The first system transported almost exclusively North Gondwana‐type, Precambrian‐aged detrital zircon sourced from siliciclastic rock units in southern Anatolia. A different drainage system is revealed by the middle to late Miocene flysch sequence that is dominated by Late Cretaceous–Cenozoic‐aged detrital zircon, whose age range is consistent with the magmatic episodicity of southeast Anatolia, along the Arabia–Eurasia suture zone. Deposition of these late Miocene strata took place thereupon closure of the Tethyan Seaway and African–Eurasian faunal exchange, and overlap in time with a pronounced uplift of eastern Anatolia. Our analytical data indicate the onset of prominent suture‐parallel sediment transport from the collision zone of south‐eastern Anatolia into the Kyrenia Range of northern Cyprus, marking the drainage response to the continental collision between Arabia and Eurasia.

“…The Hirnantian Halevikdere Formation begins with sandy diamictites, massive coarse-grained conglomeratic sandstones from the glaciomarine outwash, and clay bearing sandstones. This continues upwards with distal glaciomarine grading upwards to offshore shelf deposits of clayey sandstonesiltstone/mudstone alternations in the Adana (Kozan, Feke, Saimbeyli), Mersin (SilifkeOvacık), and Antalya (Kemer, CT) regions (Monod et al, 2003;Ghienne et al, 2010, Gürsu et al, 2017. Abundant erosion-based coarse-grained sandstone lenses with striated facets, dominant quartz clasts, a few felsic pebbles, and reworked micro-and macrofauna in the glaciomarine sequence have been reported from outcrops of the TAP and SAAB (Monod et al, 2003;Ghienne et al, 2010;Gürsu et al, 2018).…”

The Hirnantian Halevikdere Formation rests disconformably on the basement rocks and in the Mersin-Silifke-Ovacık area it is followed by fossiliferous lower Silurian to Upper Permian successions (Demirtaşlı, 1984;Kozlu et al, 2002;Koç et al, 2005;Gürsu et al, 2017Gürsu et al, , 2018.

This contribution addresses the current state of knowledge of the mainly siliciclastic Ordovician rocks in Jordan, Syria and southern Turkey including advances in palaeontology, stratigraphy, depositional facies analysis and supra-regional correlation. The extensive and excellent exposures of the sedimentary succession in southern Jordan represent the regional reference for the Ordovician System in the southern Levant. We discuss the sedimentological and faunal characteristics as well as the stratigraphy and correlation of the succession. For the northern Levant (especially southeastern Turkey) and the western and eastern Taurides, the Ordovician succession and an updated sedimentary architecture is explained and a comprehensive correlation for the region is presented. Increased knowledge on the fossil content from these regions enables correlation across the southern parts of the Arabian Plate to southern Turkey, and with the greater Gondwanan regions, far-field as southwestern Europe and northern Africa. The depositional environments in the southern and northern Levant and southern Turkey encompass non-marine to shallow-marine areas in the lower part of the Ordovician that are followed upsection by shelf deposits of variable proximity up to the glacial episode in the Late Ordovician that is tracable in each of the areas. Characteristic signals in the Ordovician succession are represented by the trans-regional early Darriwilian unconformity and by the base of the Hirnantian glacial-related deposits followed by lower Silurian strata, visible across the entire region. New data from zircon-based provenance analysis clearly implicate the Arabian Shield as the main source of the huge amount of the clastic detritus within the the Ordovician succession. In the course of the entire Cambrian-Ordovician interval, progressive deeper erosion of the Arabian Shield occurred. Sediment sources from regions farther away indicate long time of exposure and resedimentation, and some long-distant transportation, but their sedimentary influence was only of minor extent. The excellent outcrops mainly in southern Jordan, in southeastern Turkey and in the Taurides represent potential regions for further research.

Gondwana'nın kuzey kenarına ait Geç Ordovisiyen buzul kayaçlarına, Torid'lerde ve Güneydoğu Anadolu Otokton Kuşağı'nda rastlanmaktadır. Bu çalışmada; Doğu Toridler'de Feke-Saimbeyli-Ceralan (Adana) (DPK-30), Feke-Gökmenler (Adana) (DPK-44) ve Orta Toridler'de Silifke-Ovacık (Mersin) (DPK-72) bölgelerinden alınmış olan granitik buzul çakıllarından ayrılmış zirkon mineralleri üzerinde zirkon tipolojisi ve zirkon doygunluk sıcaklığı araştırmaları yapılmıştır. Zirkon tipolojisi metoduna dayanarak; çalışılan örneklerden DPK-30 örneği kalk-alkalen özellik gösteren, mafik anklavlar içeren hibrit granitoyidler, DPK-44 örneği tamamıyla veya kısmen kıtasal kabuktan oluşan, eser miktarda mafik mikrogranüler ksenolit içeriği ve düşük manto katkısı sunan granitoyidler ve DPK-72 örneği ise alkalen serisi granitoyidler olarak tanımlanan, genellikle sub-volkanik ve anorojenik komplekslerde rastlanan sıcak ve susuz magma kaynağına işaret eden manto kaynaklı kayaçlar olarak tanımlanmıştır. Bu tanımlamalar, bu kayaçlar üzerindeki izotopik verileri de kapsayan öncel jeokimyasal değerlendirmelerle genel olarak uyumludur. Çalışılan granitik kayaçların oluşum sıcaklıkları; sırasıyla zirkon tipolojisi metodu ve zirkon doygunluk sıcaklığı hesabına dayanarak, DPK-30 için 750°C ve 789°C; DPK-44 için 700°C ve 845°C, DPK-72 için 650°C ve 790°C olarak önerilmiştir. Bu sıcaklık aralıkları kaynak alan olarak önerilen Sina Yarımadası ve Mısır Doğu Çölü civarındaki Neoproterozoyik yaşlı granitoyidlerin literatürdeki mevcut sıcaklık verileriyle benzerlik göstermektedir. Sonuç olarak; zirkon tipolojisi metodu ve zirkon doygunluk sıcaklığı çalışmalarının; diğer analitik verilerle birlikte değerlendirildiğinde, granitik buzul çakıllarının kaynak alanlarının saptanmasında faydalı olabileceği düşünülmektedir.
