Foraminiferal biostratigraphy and sequence stratigraphy across the mid-Carboniferous boundary in the Central Taurides, Turkey

The Aladag Unit is one of the main tectonic units in the Tauride Belt, located in southern Turkey. It includes a continuous Paleozoic carbonate sequence encompassing the mid-Carboniferous boundary, with outcrops being especially well exposed in the Hadim region. The boundary succession lithology is mainly composed of carbonates with intercalated quartz arenitic sandstone layers. Based on foraminifers, four biostratigraphic zones have been defined in the interval from the Upper Serpukhovian to the Lower Bashkirian. These zones are, in ascending order: the Eostaffella ex gr. ikensis-E. postmosquensis Zone (Zapaltyubinsky Horizon, Upper Serpukhovian); the Plectostaffella jakhensis-P. bogdanovkensis Zone, and the Millerella marblensis Zone (Bogdanovsky Horizon, lower Bashkirian); and the Semistaffella sp. Zone (Syuransky Horizon, lower Bashkirian). The mid-Carboniferous boundary occurs between the Eostaffella ex gr. ikensis-E. postmosquensis Zone and the Plectostaffella jakhensis-P. bogdanovkensis Zone. Boundary beds are characterized by eight, repeatedly occurring microfacies types, namely: (1) coated crinoidal packstone; (2) coated bioclastic grainstone; (3) oolitic grainstone; (4) oolitic packstone-grainstone; (5) intraclastic grainstone; (6) mudstone-wackestone; (7) quartz-peloidal packstone; and 8) quartz arenitic sandstone. Based on microfacies stacking patterns, various types of shallowing-upward cycles have been recognized. Depositional sequences and sequence boundaries are correlatable with those described from North America and Russia and Carboniferous global sea-level curves. The duration of cycles has been estimated as 100 ky, suggesting that cycle periodicities correspond to the Milankovitch eccentricity band.


Foraminiferal biostratigraphy and glacioeustatic control on cyclic carbonate microfacies in the Visean-Serpukhovian boundary beds (Aladag Unit, Eastern Taurides, Turkey)
Demirel, Seda; Altıner, Demir (2016-01-01)
The Aladag Unit, one of the tectonostratigraphic units in the Tauride Belt (Turkey), comprises a nearly uninterrupted Upper Paleozoic succession including the Visean-Serpukhovian boundary beds. These boundary beds in the Eastern Taurides are made up of mainly carbonates with some intercalations of sandstone and shale. A detailed micropaleontological study has revealed three biozones based on foraminifera. These biozones are, in ascending order, Eostaffella ikensis-Vissarionovella tujmasensis Zone (Mikhailov...
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

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...
Dinoflagellate cyst biostratigraphy of Miocene strata in the Adana Basin, Eastern Mediterranean, Turkey
Turkecan, Aksel Tugba; Munsterman, Dirk; Isik, Ugras; Altıner, Demir; Pinar, Mehtap; Cevik, Tugba; Alay, Zeynep (Informa UK Limited, 2018-01-01)
The Adana Basin is one of the major Neogene basins situated in SW Turkey with sedimentary successions providing good records of the paleoenvironmental changes that affected the Mediterranean area. Since a detailed biochronostratigraphic framework has not been properly established in the Adana Basin yet, this study will be the first multidisciplinary approach carried out in this region. In addition, a detailed biozonation based on marine palynomorphs was the first ever documented from the Kopekli Formation d...
Foraminiferal fauna of Middle Permian blocks/tectonic slices from the Mersin Mélange, southern Turkey
Okuyucu, Cengiz; Tekin, Uğur Kağan; Bedi, Yavuz; Göncüoğlu, Mehmet Cemal; Sayıt, Kaan (null; 2018-03-21)
The Mersin Ophiolitic Complex from the southern Turkey is an allochthonous body including two different units as the Mersin Mélange (MM) and the Mersin Ophiolite. The MM is a sedimentary mélange including blocks and tectonic slices of oceanic and continental origin, embedded in a Late Cretaceous matrix. Based on the previous studies, these blocks in the MM are mainly originated from the northern margin of the Tauride-Anatolide terrane facing to the Northern Branch of Neotethys (Izmir-Ankara Ocean) and inclu...
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...
