The continental climatic evolution of Anatolia has been reconstructed quantitatively for the last 45 million years using the coexistence approach. Although there were some regional effects, the Anatolian Cenozoic continental climate record correlated with the European climatic condition and the global oxygen isotope record from marine environments. From middle Eocene to late Miocene, continental warming in Anatolia was pronounced for inferred winter temperature and mean annual temperature as in Europe. Generally, the palaeoclimatic property of Anatolia resembles the European climatic changing and marine temperature changing based on the oxygen isotope record; however, climatic values of the terrestrial area in Anatolia are higher from Lutetian to Aquitanian and these values are lower than European values from Aquitanian to Tortonian. Correspondingly, Cenozoic climatic cooling in Anatolia is directly associated with an increase of seasonality, palaeogeographic position and terrestrial condition. Furthermore, mean annual precipitation values of Anatolia remained relatively stable during the Eocene-Oligocene; however, these values indicated changing throughout middle-late Miocene. Moreover, in this study, decline of abundance and variables for the mangrove and back mangrove palaeocommunities during the last 45 million years is recorded because of the decreasing of humidity, temperature and increasing of terrestrial condition.

“…These dinocysts are herein used for correlating between the two studied boreholes, for dating deposits, for interpreting changes in the depositional environment because eustatic sea-level changes are considered to be the main factor in sequence formation and changes in the depositional environment (Larson et al, 2010). Other works (Bruch and Mosbrugger, 2002;Hably et al, 2007;Akkiraz et al, 2011) document that stratigraphic intervals were also analyzed to reconstruct climate and vegetation based on independent or combined quantitative approaches when applied on detailed palynological data. In ancient depositional environments (Oboh et al, 1998;Beraldi et al, 2006;Vincens et al, 2006), the diversity and abundance of palynomorphs being transported into, and preserved in the basin of deposition, are dependent on number of fundamental factors (climate, vegetation and sediment supply) as well as burial conditions.…”

A palynological investigation of two shallow boreholes in Anna, Bingerville area, at 13 km Northwest Abidjan, Southern Côte d'Ivoire, yielded rich and relatively well-preserved dinoflagellate cyst's assemblages that allowed recognition of Oligocene age. This recognition was based on global dinoflagellate cyst events, including mainly Lejeunecysta species represented by cf. Lejeunecysta communis, L. lata, L. pulchra, Lejeunecysta sp. cf. L. granosa, cf. L. globosa, L. beninensis and other Pheolodinium magnificum, P. africanum, Selenopemphix nephroïdes and Cordosphaeridium inodes. They are associated to terrestrial spores and pollen grains such as Magnastriatites howardii, Spirosyncolpites spiralis, Perfotricolpites digitatus, Retitricoporites irregularis, Retimonocolpites irregularis, Pachydermites diederixii, Psilatricolporites operculatus and Punctodiporites harrisii. The palynostratigraphic interpretations are based on a comparison with calibrated dinoflagellate cyst ranges from several reference sections, mainly in the peri-atlantic and incidentally peri-pacific basins. This study showed changes in the relative abundances of different species or groups of morphologically related species. These changes are palaeoenvironmentally controlled, indicating a deposition occurred between the continental nearshore and marginal marine areas under continental influence. The prevalence of peridinioid dinocysts assemblage suggests deposition in a subtropical province whereas terrestrial pollen grains and spores provided by plants of coastal vegetation dominated by pteridophyts and angiosperms evoke mangrove and swamp forests. These new palynological data, notably the presence of Oligocene especially in the Ivorian terrestrial basin north of the so called "faille des lagunes", specifies and modifies the previous local stratigraphic scale.

“…The bottom of the Oligocene succession (Akkiraz et al, 2011), which generally consists of conglomerates at the Kırkdağ Tepe area (Figure 7) in the southsouthwest of Atabey, is observed in the hanging wall of a northeast-southwest trending normal fault dipping northwest (Figure 7a, 7b, 7c). The relationship of the upper levels of this sequence with the pre-Oligocene basement is observed in the north of Atabey (Figure 8a, 8b).…”

“…In previous studies, it is observed that the Datça-Kale-Acı Göl basin was divided into sub-basins and different stratigraphies were proposed. The studies supplying age data for sedimentary successions rely on the facts of palynology (Akgün and Sözbilir, 2001;Akkiraz and Akgün, 2005) nannoplankton, foraminifera, mollusk (İslamoğlu et al, 2006;Gedik, 2008;İslamoğlu, 2008), palynology and benthic foraminifera (Akkiraz, 2008;Akkiraz et al, 2010Akkiraz et al, , 2011. Göktaş et al (1989), revealing the stratigraphy of the Çardak-Tokça basin, reported that they were formed by deltaic shallow marine sediments where terrigenous inputs in places are available.…”

In southwest Turkey, the Oligocene sedimentary sequence is located on the Datça-Kale-Acı Göl basin between the Menderes Massif and Lycian nappes. To understand the nature of this basin is important for tectonic models that explain the exhumation of the Menderes massif. In the northeast extension of this basin, the sedimentary sequence is interpreted as alluvial fan, fan-delta, beach, marine input, inner shelf carbonates and offshore deposits. The Oligocene Datça-Kale main breakaway fault bounding the south eastern margin of the basin is represented by İnceler and Acı Göl faults in the study area. The wedge geometry of the sequence thickening towards the İnceler normal fault is an evidence of syn-tectonic deposition. The northwest margin of the basin is controlled by two en-echelon faults. The sedimentary sequence has a wedge geometry thickening towards the normal fault and at the same time its upper layers overlap the fault. As a result, the northeast extension of the Datça-Kale-Acı Göl Oligocene basin is an elongated fjord like depositional area containing the shallow marine environments controlled by normal faults located in its southeast and northwest margins. It was demonstrated that the southeast basin margin limited by the Datça-Kale main breakaway fault performed dominant tectonic control. The similar kinematic indicators that is used for the model explaining the exhumation of the Menderes massif by the upward bending of Datça-Kale main breakaway fault are also observed in the northwest of the basin as top to the north-northeast.
