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, dominated by theinvolutinids, lagenids, and textularids. The Triasina hantkenibiozone has been established based by the presence of an index species of the late Noriyen-Rhaetian interval. The stratigraphic range of this zone is defined by the range of the key species aslate Norian-Rhaetian. In addition to eponymous species, Aulotortus sinuosus, Aulotortusfriedli, Involutinasp., Galeanellasp., Duostominasp., Glomospirasp., Glomospirellasp., Duotaxisbirmanica, Siphovalvulinasp., and Reophaxsp. are the other foraminiferal taxa recorded in the Upper Triassic carbonates. Based on the detailed microfacies analysis, the Upper Triassic carbonates of the section are represented by the following microfacies typesrepresenting shallow marine environments:mudstone, wackestone-packstone, pelloidal bioclastic packstone-grainstone. These defined microfacies types are characteristics of the subtidal and intertidal deposits. Alternating volcanic rocks are mainly alkaline basalts with aphanitic texture. They have P-MORB affinities with enrichment of light rare earth elements over heavy rare earth elements and would be originated from garnet bearing mantle source.

Foraminiferal assemblages and microfacies analysis of Upper Triassic volcanosedimentary successions in Plau region (Elazığ, Turkey)

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...
Foraminifera, Radiolaria and Conodont assemblages from the Early Mississipian (late Tournaisian)/Early Pennsylvanian (early Bashkirian) blocks within the Mersin Melange, southern Turkey: Biochronological and paleogeographical implications
OKUYUCU, CENGİZ; TEKİN, UĞUR KAĞAN; Noble, Paula J.; Bedi, Yavuz; Saydam-Demiray, D. Gulnur; Sayıt, Kaan (2018-12-01)
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 (Ea...
Foraminiferal fauna of some Carboniferous–Permian blocks from the Mersin Mélange (Central Taurus, Southern Turkey): A correlation with carbonate successions in adjacent Tauride tectonic units
Okuyucu, Cengiz; Tekin, Uğur Kağan; Bedi, Yavuz; Göncüoğlu, Mehmet Cemal; Sayıt, Kaan; Uzunçimen Keçeli, Seda (Kazan Federal University; 2015-08-15)
The Mersin Complex from Southern Turkey is composed of two different tectonic units as; the Mersin Mélange, and the ophiolitic series with a metamorphic sole. The Mersin Mélange is composed of blocks of various origins with different stratigraphic ranges within a Late Cretaceous matrix. The foraminiferal contents of three limestone blocks of the Carboniferous and Permian age from the Mersin Mélange have been studied to evaluate their origin, to determine their total stratigraphic range and to correlate them...
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...
