The Hadim Nappe has a relatively complete succession from the Middle(?)–Upper Devonian to Upper Cretaceous in the Taurides. The Bademli section is one of the well exposed sections of theHadim Nappe that is selected for detailed biostratigraphic investigations. It includes a continuous Viséan stratigraphic succession. In the Bademli section, rich and diverse Early-Middle Viesean foraminiferal assemblages were recovered, most of which were reported for the first time in Turkey. Four first occurrence biozones, which approximately correspond to the Zones MFZ10 to MFZ13 of the Belgium stratotype section, are identified based on the foraminiferal analysis of the Lower-Middle Viséan strata of the Bademli section that are Ammarchaediscus-Glomodiscus first occurrencezone, Uralodiscus rotundus first occurrence zone, Pojarkovella first occurrence zone and Endothyranopsis (Reitlingeropsis) intermedia - Endothyranopsis mosquensis first occurrence zone.

ABSTRACT The Hadim Nappe which is one of the allochthonous tectonic units in the Tauride Belt includes continuous stratigraphic successions from Middle(?)-Late Devonian to Late Cretaceous. The well exposed successions of the Moscovian to lower Kasimovian are selected for fusulinid biostratigraphy along three sections (Yassıpınar, Gölbelen and Bademli) in the Central Taurides. The Lower-Middle Pennsylvanian boundary was determined by the first appearance datum of the Aljutovella aljutovica (Rauzer-Chernousova, 1938) and Solovievaia ovata ovata (Rauzer-Chernousova, 1938). In this study, the Vereian, Kashirian, Podolskian and Myachkovian regional substages of the Moscovian stage were determined by Aljutovella aljutovica-Solovievaia ovata ovata, Aljutovella priscoidea (Rauzer-Chernousova, 1938), Eofusulina triangula (Rauzer-Chernousova & Belyaev in Rauzer-Chernousova, Belyaev & Reitlinger, 1936), Fusulinella vozhgalensis devexa Rauzer-Chernousova in Rauzer-Chernousova, Gryzlova, Kireeva, Leontovich, Safonova & Chernova, 1951, Beedeina schellwieni (Staff in Schellwien & Staff, 1912) and Fusulinella bocki bocki Möller, 1878 in ascending order. The base of the lower Kasimovian is represented by the occurrence of Quasifusulinoides Rauzer-Chernousova & Rozovskaya in Rauzer-Chernousova & Fursenko, 1959, Protriticites Putrya, 1948 and Montiparus Rozovskaya, 1948 taxa. A total of 106 fusulinid species belonging to 19 genera were determined. One genus and ten species are new: Aljutovella typica Akbaş, n. sp., Beedeina minuta Akbaş, n. sp., Beedeina tauridiana Akbaş, n. sp., Praefusulinella guvenci Akbaş, n. gen., n. sp., Praefusulinella okuyucui Akbaş, n. gen., n. sp., Praefusulinella rhombiforma Akbaş, n. gen., n. sp., Praefusulinella tekini Akbaş, n. gen., n. sp., Fusulinella absoluta Akbaş, n. sp., Fusulinella obtusa minuta Akbaş, n. subsp. and Fusulinella propriaforma Akbaş, n. sp. The taxonomic positions of some fusulinids species (e.g., Neostaffella larionovae polasnensis (Rauzer-Chernousova & Safonova in Rauzer-Chernousova, Gryzlova, Kireeva, Leontovich, Safonova & Chernova, 1951), Depratina chernovi (Rauzer-Chernousova, Gryzlova, Kireeva, Leontovich, Safonova & Chernova, 1951), Solovievaia arta (Leontovich in Rauzer-Chernousova, Gryzlova, Kireeva, Leontovich, Safonova & Chernova, 1951) and Beedeina paradistenta (Safonova in Rauzer-Chernousova, Gryzlova, Kireeva, Leontovich, Safonova & Chernova, 1951) were revised. The fusulinid assemblages recovered in this study correlate well with the Russian Platform, Cantabrian Mountains, Central Iran, southern Urals, Donets Basin, and some other regions of the Tethyan Realm. RÉSUMÉ Biostratigraphie des fusulinidés du Moscovien-Kasimovien inférieur de la nappe de Hadim, Taurides centrales, sud de la Turquie. La nappe de Hadim, qui est l'une des unités tectoniques allochtones de la ceinture des Taurides, comprend des successions stratigraphiques continues du Dévonien moyen(?)-supérieur au Crétacé supérieur. Les successions bien exposées du Moscovien au Kasimovien inférieur sont sélectionnées pour la biostratigraphie des fusulinidés le long de trois coupes (Yassıpınar, Gölbelen et Bademli) dans les Taurides centrales. La limite Pennsylvanien inférieur-moyen a été déterminée par la date de première apparition d'Aljutovella aljutovica (Rauzer-Chernousova, 1938) et de Solovievaia ovata ovata (Rauzer-Chernousova, 1938). Dans cette étude, les sous-étages régionaux véréien, kashirien, podolskien et myachkovien de l'étage moscovien ont été déterminés par Aljutovella aljutovica-Solovievaia ovata ovata, Aljutovella priscoidea (Rauzer-Chernousova, 1938), Eofusulina triangula (Rauzer-Chernousova & Belyaev in Rauzer-Chernousova, Belyaev & Reitlinger, 1936), Fusulinella vozhgalensis devexa Rauzer-Chernousova in Rauzer-Chernousova, Gryzlova, Kireeva, Leontovich, Safonova & Chernova, 1951, Beedeina schellwieni (Staff in Schellwien & Staff, 1912) et Fusulinella bocki bocki Möller, 1878 en ordre croissant. La base du Kasimovien inférieur est représentée par l'occurrence des taxons Quasifusulinoides Rauzer-Chernousova & Rozovskaya in Rauzer-Chernousova & Fursenko, 1959, Protriticites Putrya, 1948 et Montiparus Rozovskaya, 1948. Un total de 106 espèces de fusulinidés appartenant à 19 genres a été déterminé. Un genre et dix espèces sont nouveaux: Aljutovella typica Akbaş, n. sp., Beedeina minuta Akbaş, n. sp., Beedeina tauridiana Akbaş, n. sp., Praefusulinella guvenci Akbaş, n. gen., n. sp, Praefusulinella okuyucui Akbaş, n. gen., n. sp., Praefusulinella rhombiforma Akbaş, n. gen., n. sp., Praefusulinella tekini Akbaş, n. gen., n. sp., Fusulinella absoluta Akbaş, n. sp, Fusulinella obtusa minuta Akbaş, n. subsp. et Fusulinella propriaforma Akbaş, n. sp. La position taxonomique de certaines espèces de fusulinidés (par exemple, Neostaffella larionovae polasnensis (Rauzer-Chernousova & Safonova in Rauzer-Chernousova, Gryzlova, Kireeva, Leontovich, Safonova & Chernova, 1951), Depratina chernovi (Rauzer-Chernousova, Gryzlova, Kireeva, Leontovich, Safonova & Chernova, 1951), Solovievaia arta (Leontovich in Rauzer-Chernousova, Gryzlova, Kireeva, Leontovich, Safonova & Chernova, 1951) et Beedeina paradistenta (Safonova in Rauzer-Chernousova, Gryzlova, Kireeva, Leontovich, Safonova & Chernova, 1951) a été révisée. Les assemblages de fusulinidés retrouvés dans cette étude sont bien corrélés avec la Plate-forme Russe, les Montagnes Cantabriques, l'Iran Central, le sud de l'Oural, le bassin de Donets et quelques autres régions de la Téthys.

AbstractThe Hadim Nappe, which is one of the allochthonous tectonic units in the Tauride Belt, in southern Turkey, includes a continuous stratigraphic succession from the Middle(?)–Late Devonian to Late Cretaceous. A relatively complete succession of the upper Serpukhovian to Bashkirian is exposed in the Central Taurides, where two sections (Yassıpınar and Gölbelen) have been selected for detailed biostratigraphic investigations. The Mississippian-Pennsylvanian boundary in these sections was determined by the first appearance datum of thePlectostaffella jakhensisand located in the oolitic limestone facies indicating a shallow-water depositional environment. The uppermost Serpukhovian and regional Bashkirian substages (Syuranian, Akavasian, Askynbashian, and Arkhangelskian) were determined by index taxa, namelyPlectostaffella jakhensis,P.bogdanovkensis,P.varvariensis,Pseudostaffella antiqua,Staffellaeformes staffellaeformis,Tikhonovichiella tikhonovichi, andVerella spicata. Fifty fusulinid species belonging to fourteen genera were determined in two sections, in which two species are new:Depratina turaniAkbaş new species andTikhonovichiella praetikhonovichiAkbaş new species. The taxonomic positions of two fusulinid species (Depratina convolutan. comb. andStaffellaeformes parva robustan. comb.) are revised. The studied fusulinid assemblages correlate with fusulinid assemblages from the southern Urals, Russian Platform, Donetz Basin, Darvaz, Spain, central Iran, and some other regions of the Tethyan Realm.UUID:http://zoobank.org/bcbb6c72-f6f9-4e77-9cf9-3572bd731ff3
