A HP-LT metamorphism (M0) recognized in the lower tectonic units of the Paikon Massif predates the D 1 event and is possibly related to subduction and collision. Oligocene to early Miocene sediments deposited between folds display tilted onlap-ping to flat onlapping relationships with the folds. changes on closure of Panama and the major eruption of the Columbia They hold the record of how neritic biologic communities reacted to palaeoenvironmental changes. Here we summarize the state of the art in the field of Larger Benthic Foraminifera (LBF) and sketch the main lines of research that are improving the precision and usefulness of this scale. Pennsylvanian, Asturias, N Spain, cf. sp. Such environments allow documentation of warming episodes associated with sudden immigration of warm water and exotic forms of SWWBF that evolved elsewhere into the area. since the Jurassic, tracing the north-eastern basement high and While the Görbiyesdağı Unit is represented by Upper Cretaceous Sipahili formation, the Geyikdağı Unit is divided into two tectonic slices as being Ovacık and Araca tectonic slices. rate coupled with enduring thermal subsidence, on-going rise of the Basins to the south. Lithostratigraphy and larger foraminiferal (nummulitid) biostratigraphy of the Tertiary of Northern Oman. Ben-Eliahu, Nir; Herut, Barak; Rahav, Eyal; Abramovich, Sigal. Foraminifera [von *foraminifer-], (d´Orbigny 1826), Foraminiferida, Foraminiferen, Porentierchen, Lochträger, Kammerlinge, Thalamophora, artenreiche (rezent ca. This is one of the most precise sequences, not only in this area, but also among former shallow marine deposits of the entire Neotethyan realm in the present Mediterranean region. American ancestors, was found in the Burdigalian. Large benthic foraminifera are single celled organisms with a calcareous test, or “shell,” which has a complex and often very beautiful internal structure. The glossary includes some 650 entries illustrated by 83 - often composite – figures many of which are stereographs or 3D models. The biostratigraphy of these subdivisions and main genera is summarized. Large benthic Foraminifera show a diverse and flexible association with prokaryotic organisms (Prazeres et al., 2017a), but can also acquire new eukaryotic symbionts to suit their environment across broad geographical scales (Momigliano and Uthicke, 2013). foreland phase is assigned to this time as well as changes in the stress EAGE Publications bv, 101À162. : Mémoires suisses de paléontologie. The fusulinids Beedeina and Wedekindellina appeared during widespread early Desmoinesian transgressions and characterized that interval. The Paleocene interval is characterized by moderate to low amplitude, continuous to discontinuous reflections that thicken to the west. The chronostratigraphical position of some localities was ascertained from planktic and larger benthic foraminifera, as well as calcareous nannoplankton. The origin and the petroleum potential of the Song Hong, Phu Khanh, Malay - Tho Chu and the 4⁰ texte: II, 244 p. fig. This continued during the Eocene, accompanied by decrease in deposition rates, except of the Magura Basin. Jurassic to Cretaceous Palaeo-Pacific subduction resulted in the creation of a magmatic arc that now Polyphase deformation and metamorphism affected, The integrated analysis of seismic, well log and outcrop data from the Cenozoic section of the northern San Jacinto Fold belt (SJFB) in NW Colombia, revealed a complex tectonic evolution from Paleogene extension to Neogene compression and inversion. This was complemented by the interpretation of new 2D-seismic in the northernmost portion of the SJFB. The upper Virgilian has mostly large inflated Triticites and the first Leptotriticites.

On the other hand, the genus Pseudocyclammina in the Lias has been revised, and an emendation of P. liassica Hottinger (1967) is proposed; this species characterize the last biozone (E) of the Lias. Large benthic foraminifera (LBF) are an important component of low-light, mesophotic tropical marine environments, including coral ecosystems. The F2–3 facies with planktonic, large and small hyaline benthic foraminifers and corallin algal indicate a distal to proximal middle ramp setting. coupled with important basin subsidence at Andes foothills. Strontium isotope stratigraphy indicates that the oldest species, O. hottingeri, made its first appearance in the earliest Campanian, close to the Santonian-Campanian boundary, and was replaced by O. sanctae-pelagiae at a level closely corresponding to the boundary between the Placenticeras bidorsatum and Menabites delawarensis ammonite zones. together with their American ancestors, at the end of the Burdigalian; a Paleocene to Miocene units contain both potential source rocks and main reservoirs, though Cretaceous source rocks may also be active in the area. - 2 vol. The shell itself acts as a recorder of the ambient water chemistry in low to extreme HMs-polluted environments, allowing the monitoring of recent-past pollution events. In Tethys the larger benthic foraminifera reached an acme of abundance and diversity during the Middle Eocene, including some of the largest known forms. The convergent-margin stratigraphy in the Sonoma-Livermore Province is difficult to reconstruct for the successor basins because of sparse outcrop exposures and overlying strike-slip stratigraphy and faulting. It provides documentation of the biostratigraphic ra rudimentary, and the stratigraphic ranges of genera of Tethyan forms In the updated orthophragminid zonation (zones are marked by OZ), OZ la corresponds to the early Thanetian, OZ lb to the middle Thanetian. In the Neogene the only genus known so far is Neosemantis that occurs sporadically since the lower Miocene. This leads to uncertainties in paleobathymetric estimation, and thus widens error margins of subsidence analysis. This actualistic study examines the potential of large benthic foraminifera to serve as proxies for the presence, taxonomic composition, density, and environmental variables of ancient These units are "Geyikdağı Unit" and, In Mongolia, fossil mammals are known from the Upper Jurassic, Lower and Upper Cretaceous, all series of the Paleogene and Neogene, as well as the Pleistocene. Much slumping occurred during the Cretaceous in the eugeosyncline. ), 2) clarifying the relationship between the umbilical canal system and the laminar deposits in Late Jurassic–Cretaceous coscinoconins, 3) emending and providing new combinations for “Trocholina” lenticularis Henson, 1947, “T.” minima Henson, 1947, and “T.” burlini Gorbatchik, 1959, which have been repeatedly misidentified in the literature, 4) discussing the epibenthic mode of life of trocholinids, and 5) proposing an explanation for their extinction at the Cenomanian – Turonian boundary. There are two major northwest-southeast lines of thrusting and overturned folding, and two major tectonic windows (Alpi Apuane and Monte Pisano), in which the Tuscan sequence is doubled.4. Public Health 2020, 17, 3741. - from English summary. in cases of intense recrystallization, are presented. subord. The stratigraphic section for this province is for the Livermore Basin (McLean, 1993). Bassoullet, J.P., 1997. ; Lituobellina n. Main tectonic events are identified representing Africa forms a new distinct bio-province. Diss. The tectonically driven closure of the seaway between the Mediterranean of Indo-Pacific fauna, led by their eventual extinction in the Langhian. 1. It notably allows 1) describing one new subfamily (Coscinoconinae n. By comparing the stratigraphic ranges of the South American specimens with previously described Tethyan forms, the phylogenetic evolution of the lepidocyclinids is reconstructed from their mid-Eocene origin in the Americas to their late Miocene (or possibly early Pliocene) extinction in the Indo-Pacific.

See further details. events at this stage, triggered a crisis for the Mediterranean The main outcomes of this work are that 1) Neotrocholina Reichel is definitively excluded from the Involutinina; 2) the genera Andersenolina Neagu, Hottingerella Piller, and Septatrocholina BouDagher-Fadel and Banner are placed in synonymy with Coscinoconus Leupold; 3) the genus Ornatoconus di Bari is considered a synonym of Trocholina Schlumberger; 4) the distinction between the genera Auloconus Piller and Lamelliconus Piller is abandoned; 5) five new genera (Coronaserra n. gen., Frentzenella n. gen., Kristantollmanna n. gen., Papillaconus n. gen., and Wallowaconus n. gen.) and three new species (Frentzenella frentzeni n. gen., n. The earliest Missourian is barren of fusulinids in the Midcontinent, followed by a thin zone of Eowaeringella, and then the appearance of Triticites, which dominated fusulinid faunas through the remainder of the Upper Pennsylvanian. The species Praealveolina iberica, P. pennensis and P. debilis successively replace each other from Early to Mid Cenomanian; they have been correlated with Mantelliceras mantelli and Acanthoceras rotomagense ammonite zones, and with Rotalipora brotzeni and the lower part of the R. cushmanni planktonic foraminiferal zones. Nassellarian-like spicular Radiolaria range within the boundaries of the Triassic; they seem to have disappeared by the end on the Norian.In order to give a complete inventory of these radiolarians all taxa known in the Mesozoic and lower Cenozoic are described, discussed, or just mentioned. ), two new genera (Hensonipapillus n. gen. and Paracoscinoconus n. gen.), and five new species (Coscinoconus discoideus n. The postgeosynclinal sediments are Upper Miocene to Pleistocene in the southwest (Tuscany-Latium), Pliocene and Pleistocene in the northeast and east (Emilia and Marche).Four major structural areas are distinguished: 1. phase) resulted in enhanced sedimentation rates during the Paleocene, Thickness St. U.

Groupe Francais d'Etude du Jurassique. Abb. During the Carboniferous and Permian, large fusulinid foraminifera are Neogene assemblages are dominated by a variety of large miliolids such as the soritids and by rotaliids (including the stratigraphically useful miogypsinids and lepidocyclinids Please let us know what you think of our products and services. Middle Jurassic Sequence of the Arabian Plate. The rapid diversification and widespread distribution characterizing the group suggest that Benthic foraminifera live, attached or free, at all depths, and include a major group of foraminifera with complicated internal structures, the so called “larger benthic foraminifera”. Quaternary deposits overlie the older units with angular unconformity in the styudy area. Fusulinid zonal boundaries that were based on only fusulinid species ranges were found to closely approximate maximum sea level lowstands. This is the result of discussions on the subject during a workshop held in Lausanne in October 1989. Large benthic foraminifera are significant contributors to sediment formation on coral reefs, yet they are vulnerable to ocean acidification. The number of auxiliary chamberlets, reflecting the number of apertures in the wall of the embryo, and the number of nepionic chambers with only one aperture are considered to be the main features for distinguishing the species. Syn-D 1 metamorphism did not exceed greenschist facies conditions (M 1). (ed), Lower Triassic to The statements, opinions and data contained in the journals are solely Key Words: Central Taurus, Silifke, Tectono-Stratigraphy, Tectonic Evolution. Exceptionally well-preserved trochospirally coiled Involutinina have been found in Late Triassic (Wallowa Mountains, Oregon, Skeletal grainstone with cross-sections of beresellid algae and two well preserved specimens of the textularid foraminifer Climacammina (centre left) and Bradyina (top right) in a calcite spar mosaic. This second edition is substantially revised, including extensive re-analysis of the most recent work on Cenozoic forms. Extensional collapse and exhumation took place during Oligocene to Miocene, associated with brittle low-angle normal faults, with a main top-to-the-SW sense of movement (D 5). range of the family Trocholinidae Kristan-Tollmann. The Franciscan Formation and Pliocene volcanic rocks occur in the northeast part of the province. The comparison of superposed praealveolinid assemblages from the well exposed outcrops in the Iberian Range and the Pyrenees with Prealveolina species from the type localities in Reichel's collection have allowed us to evaluate the stratigraphical range of each species. Climatic changes also had little effect upon provinces beyond causing them to expand and contract latitudinally in response to warming and cooling phases. En libr. London, WC1E 6BT, UK One of the notable features of the Oligocene The palaeobiogeographic characteristics of biotopes and the composition of foraminiferal assemblages during the Mesozoic were controlled by the position of the study area within the Neotethyan bioprovinces. ; Pseudoammodiscina emend. The geology in the Sonoma-Livermore Province is further complicated by the Mendocino triple junction which transformed a convergent continental margin into a strike-slip margin in the middle Miocene (14-13 Ma). The larger benthic foraminiferal family Lepidocyclinidae has been described extensively in the literature, with occurrences ranging from the middle Eocene in the Americas to the late Miocene (or possibly early Pliocene) in the Indo-Pacific Tethyan sub-province. Larger benthic foraminifera: a tool for biostratigraphy, facies analysis and paleoenvironmental interpretations of the Oligo-Miocene carbonates, NW Central Zagros Basin, Iran. The stratigraphic relationship of P. cretacea and P. lata with the species treated in this paper have not been established yet because they were not found in the studied sediments. are introduced; 6) the species “Trocholina intermedia” Henson is reinstituted; 7) “Trocholina gigantea” Pelissié and Peybernès, and “Semiinvoluta verrucosa” Tollmann and Kristan-Tollmann are renamed Coscinoconus limognensis nom. We measured growth rates (surface area and buoyant … A possible extensional event before D2 may be related to the deposition of the Upper Jurassic-Lower Cretaceous carbonate sediments. The structural differences warrant separate generic names for the alveolinacean associations on either side of the Atlantic. Compressed alveolinaceans characterize the Caribbean on one hand, the Western Neotethys on the other. Emended and new taxa are: Tuberitinoidea emend. Biostratigraphy and biogeography of Jurassic They occur in bioclastic for-algal grainstones and near-reefal rudstones referred to platform margin environments. Speciation, phylogenesis, tectonism, climate and eustasy: factors in the evolution of Cenozoic larger foraminiferal bioprovinces. Discocyclina archiaci and D. dispansa substituted D, seunesi at about the Paleocene/Eocene boundary. A SBZ zone is characterized upon the stratigraphie distribution of several taxa, belonging mainly to alveolinids, nummulitids and orthophragminids. Recovery from the end-Cretaceous extinction event was slow, but by the Late Paleocene, large rotaliids, such as nummulitids and discocyclinids, were abundant in tropical seas along with a resurgence of the alveolinids. The Görbiyesdağı and the Geyikdağı units are unconformably overlain by Lower Miocene age Tepeköy and Çavuşlar formations which are assumed to be cover deposits, and Middle Miocene Mut formation. These factors are examined in relation to the development, through dispersal/migration, of the 3 main Cenozoic faunal provinces (Central American, Mediterranean and Indo-West Pacific). Paleobiology 11, 195 – 208 (1985). A single lineage zone (Zone of O. hottingeri) characterizes the Santonian. This event was associated with a large negative carbon isotope excursion (CIE) and with major changes in the atmosphere, hydrosphere, and biosphere. The belonging of the species to the genus Dictyoconella Henson however is challenged, as the type-species Dictoyconella complanata in contrast does not display an orbitolinid test architecture. However, some additional rotaliid taxa, from the Late Cretaceous or that do not belong to the family Rotaliidae sensu stricto, are included in this book in order to demonstrate particular roots of rotaliid phylogenetic lineages in the previous community maturation cycle or to delimit the taxon Rotaliidae with more precision. This displaced fauna, along with the volcanic material, undoubtedly moved downslope from a topographic high adjacent to the site. Tectonostratigraphic data reveal that both have been affected by the same polyphase deformation and metamorphism, as well that they have the same lithostratigraphic column.

The Paikon Massif is part of the Axios Zone and consists of Triassic marbles intercalated with schists and phyllites, overlain by volcanoclastic and carbonate rocks of Jurassic to Early Cretaceous age, as well as ophiolites. The taxonomic significance of canaliculi is discussed and it is concluded that the development of canaliculation is gradational and that their presence or absence cannot always be used to define supraspecific differences.
