The middle Miocene palynofloras of the Salihpaşalar lignite mine (Yatağan Basin, southwest Anatolia): environmental characterisation and comparison with palynofloras from adjacent basins

Abstract As the third part of an ongoing investigation of middle Miocene palynofloras in the Yatağan Basin (YB), southwestern Anatolia, the palynofloras of the Salihpaşalar lignite mine in the main YB were studied. Seven types of algal spores, aplanospores/zygospores or cysts, six types of lycophyte and fern spores, 12 types of gymnosperm pollen and 90 types of angiosperm pollen were identified. Of a total of ca. 140 plant taxa described from the YB, over 10% are confined to the Salihpaşalar assemblage. Differences between coeval palynofloras of the Sekköy Member might reflect changing or prograding depositional environments. A number of rare accessorial taxa reflect these local differences: Pilularia, Valeriana, Drosera and Persicaria aff. amphibia only occur at Salihpaşalar and are typical of shallow water or temporary ponds associated with a lake shore. Apart from this, all the palynofloras, originating from the lignite seams and overlying limnic limestones (uppermost Turgut and Sekköy Member), of the YB are strongly indicative of extensive woody vegetation with a dominance of diverse Fagaceae and Pinaceae. In addition, a list comparing the well-documented YB palynomorphs to morphologically similar palynomorphs of published late early to middle Miocene plant assemblages of western Anatolian was compiled. Such a comparison reveals that in many instances different taxon names have been used to denote the same taxa. Hence, resolving these synonymies is a prerequisite of any meaningful comparison of palynofloras in the region.

The Relationship

Abstract The global Monterey excursions are recognized in many deep-sea, and recently in shallow water depth records during the Miocene epoch. We analyzed the δ 13C and δ 18O to investigate the relationship between the lithostratigraphic units and the deviation of the stable isotopes. The results show that there is a significant relationship between the depositional energy changes and both of δ 13C and δ 18O. The present paper is deals with variability of the primary isotopic composition of seawater in the shallow water zone. Sedimentary successions of middle Miocene outcropping in the eastern part of Iraq provide an excellent archive of the oxygen isotope events (Mi‐events), additional details about Mi 2 and Mi 3 zones of glaciations and refine the Monterey Excursion, carbonate isotope maxima (CM‐events). Facies analysis revealed several microfacies could be distinguished, reflecting depositional environments including; lagoon, back reef-reef, shallow open marine, and shoal environments. The Jeribe Formation is a transgression unit belonging to the stage Ap11 tectonostratigraphy Megasequence. The Formation was deposited in the outer platform margin of unstable shelf of the Arabian Plate and significant of this formation, which is deposited during the final phase of Tethys sea closure. The stable isotope (18O/16O and 13C/12C) provide an excellent archive of the paleoceanography for the Neogene (middle Miocene Transgression) of the Neo-Teythys. Oxygen and carbon isotopic stratigraphy for bulk-rock were analyzed in order to distinguished Monterey Event and climate optima.

In 2015 the locality Borač-Podolí was newly examined. The locality is situated 8 km NW from the town of Tišnov. A large amount of shallow-water fossils of middle Miocene (Badenian) age was collected. The state of preservation of the material enabled us bivalve borings of ichnogenus Gastrochaenolites which were bored into colonies of hermatype corals and other calcareous hard substrates. In some of these borings, bivalves were found in situ. The borings were determined as Gastrochaenolites isp., Gastrochaenolites orbicularis, Gastrochaenolites lapidicus, Gastrochaenolites dijugus and Gastrochaenolites torpedo. The in situ bivalves were determined as Gastrochaena cf. intermedia, Rocellaria cf. dubia, Hiatella arctica and Cardita calyculata. The first three species probably represent primary borers while Cardita calyculata is probably a secondary user (squatter). Based on an analysis of fossil material, we can assume that borings were created aft er the death of corals during the repeated transport of these bioclasts. It led to colonizing of the whole surface of coral bioclasts. The bioclasts were then moved to deeper water. Transport to water with clay sedimentation enabled the preservation of the bivalves in situ in borings.

Sandy Sediments

AbstractThe present article focuses predominantly on sandy deposits that occur within the Middle Miocene lignite seam at the Tomisławice opencast mine, owned by the Konin Lignite Mine. As a result of mining activity, these siliciclastics were available for direct observation in 2015–2016. They are situated between two lignite benches over a distance of ~500 m in the lower part and ~200 m in the higher part of the exploitation levels. The maximum thickness of these sandy sediments, of a lenticular structure in a S–N cross section, is up to 1.8 m. With the exception of a thin lignite intercalation, these siliciclastics comprise mainly by fine-grained and well-sorted sands, and only their basal and top layers are enriched with silt particles and organic matter. Based on a detailed analysis of the sediments studied (i.e., their architecture and textural-structural features), I present a discussion of their genesis and then propose a model of their formation. These siliciclastics most likely formed during at least two flood events in the overbank area of a Middle Miocene meandering or anastomosing river. Following breaching of the natural river levee, the sandy particles (derived mainly from the main river channel and levees) were deposited on the mire (backswamp) surface in the form of crevasse splays. After each flooding event, vegetation developed on the top of these siliciclastics; hence, two crevasse-splay bodies (here referred to as the older and younger) came into existence. As a result, the first Mid-Polish lignite seam at the Tomisławice opencast mine is currently divided in two by relatively thick siliciclastics, which prevents a significant portion of this seam from being used for industrial purposes.

Abstract. Late Middle Miocene (Upper Badenian) strata of the Fore-Carpathian Depression of Poland yield a shallow-water ostracod fauna which contains the species Triebelina raripila (G. W. Müller, 1894) and Carinocythereis carinata (Roemer, 1838). The palaeobiogeographic distribution of the two main species suggests, that in the late Middle Miocene, Central Paratethys was still connected to the Mediterranean, although still separated from the Eastern Paratethys and from southeastern Eurasia. The continuous occurrence of Triebelina raripila and Carinocythereis carinata in the Mediterranean basins, from the Early Miocene to Recent, indicates that marine conditions existed throughout, thereby allowing them to survive the Late Miocene salinity crisis.

Germanostenolestes lutzi, new genus and species of Sieblosiidae is described from the Middle Miocene of Öhningen (Germany). It probably belongs to the clade (Paraoligolestes + (Parastenolestes (Germanolestes + Stenolestes))) sensu Nel et al. (2005). It is the third representative of the Sieblosiidae described from this outcrop, showing that this family was still quite diverse in the Middle-Late Miocene.
