Subtidal, intertidal, and supratidal carbonate facies are recognized in the Upper Jurassic (Kimmeridgian)-Upper Cretaceous (Cenomanian) peritidal carbonates of the Fele area (Western Taurides, Turkey). Vertical stacking patterns of these facies are of a cyclical character, shallowing upward is the trend of the cyclicity in these carbonate facies. In-situ karstic breccias, collapse breccias, caliche (laminar calcrete), "Microcodium" accretion, and root casts are structures commonly indicative of third-order sequence boundaries. However, mud cracks, solution pores or vugs, sheet cracks, loferites, and birds-eye structures are commonly delineated by parasequence boundaries. In-situ or collapse breccias can be genetically derived from sheet cracks, mud cracks, solution pores or vugs, and birds-eye structures with increasing exposure time. The use of such sedimentary structures in the recognition of sequence boundaries is highly practical in the ancient carbonate platforms of the world, inasmuch as the sequence boundaries, as demonstrated in this study, correlate with the eustatic sea level curves.

Rapid cooling history of a Neotethyan ophiolite: Evidence for contemporaneous subduction initiation and metamorphic sole formation PARLAK, OSMAN; Dunkl, Istvan; KARAOĞLAN, FATİH; Kusky, Timothy M.; Zhang, Chao; Wang, Lu; Koepke, Juergen; Billor, Zeki; Hames, Willis E.; ŞİMŞEK, EMRAH; Simsek, Gokce; ŞİMŞEK, TUĞÇE; Ozturk, Selena Ezgi (Geological Society of America, 2019-11-01) The Beywhir-Hoyran Nappes, including Mesozoic carbonate platform rocks, deepsea sediments, and ophiolite-related units, crop out extensively on the western limb of the Isparta Angle in the Central Taurides, Turkey. The ophiolite-related rocks are represented by variably serpentinized harzburgitic mantle tectonites, tectonically underlain by a subophiolitic metamorphic sole and melange. The harzburgitic mantle tectonites and metamorphic sole are intruded by undeformed isolated dikes. Protoliths of the metamo...
Erosional truncation of uppermost Permian shallow-marine carbonates and implications for Permian-Triassic boundary events Payne, Jonathan L.; Lehrmann, Daniel J.; Follett, David; Seibel, Margaret; Kump, Lee R.; Riccardi, Anthony; Altıner, Demir; Sano, Hiroyoshi; Wei, Jiayong (Geological Society of America, 2007-07-01) On shallow-marine carbonate buildups in south China, Turkey, and Japan, uppermost Permian skeletal limestones are truncated by an erosional surface that exhibits as much as 10 cm of topography, including overhanging relief. Sedimentary facies, microfabrics, carbon isotopes, and cements together suggest that erosion occurred in a submarine setting. Moreover, biostratigraphic data from south China demonstrate that the surface postdates the uppermost Permian sequence boundary at the global stratotype section a...
EVIDENCE AGAINST THE CORE COVER INTERPRETATION OF THE SOUTHERN SECTOR OF THE MENDERES MASSIF, WEST TURKEY Bozkurt, Erdin; WINCHESTER, JA (Wiley, 1993-01-01) The Menderes Massif, in western Anatolia, has been described as a lithological succession comprising a basal 'Precambrian gneissic core of sedimentary origin' overlain in sequence by 'Palaeozoic schist' and 'Mesozoic-Cenozoic marble' forming the envelope. The boundary between core and schist envelope was interpreted as a major unconformity, the 'Supra-Pan-African unconformity'. By contrast, our field observations and geochemical data show that around the southern side of Besparmak Mountain, north of Selimiy...
Pseudomarssonella REDMOND 1965 (Foraminifera) and related taxa from the Jurassic platform carbonate succession of the Central Taurides, S Turkey: its phylogenetic relation with the subfamily Paleopfenderininae TASLI, Kemal; Altıner, Demir (EDP Sciences, 2010-01-01) Pseudomarssonella and related taxa have been recorded in the upper part of the Redmondoides lugeoni/Redmondoides cf. rotundatus Zone, Paleopfenderina trochoidea-salernitana and Kurnubia ex. gr. palastiniensis zones, and the lower half of the Clypeina jurassica Zone, from the Bathonian to the lower Tithonian of the Central Taurides (S Turkey) inner platform carbonate succession. A tentative phylogenetic tree of the Jurassic pfenderinids (paleopfenderins) is given in this study. The Paleopfenderininae are sug...
Extensional v. contractional origin for the southern Menderes shear zone, SW Turkey: tectonic and metamorphic implications Bozkurt, Erdin (Cambridge University Press (CUP), 2007-01-01) The southern Menderes Massif in southwest Turkey consists mainly of orthogneisses and overlying Palaeozoic-Middle Paleocene schists and marbles. The contact between the two distinct rock types is almost everywhere structural, herein named the southern Menderes shear zone: a S-facing, high-angle ductile shear zone that separates metamorphic rocks of differing grade. Although there is a consensus that the shear zone was associated with top-to-the-S-SSW shearing and is of Tertiary age, its origin and nature ha...
