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. Jurassic to Cretaceous Palaeo-Pacific subduction resulted in the creation of a magmatic arc that now 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. To identify the impact of the tectonic 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). In the Phu Khanh basin oil seepages and an offshore oil discovery prove the presence of active petroleum Larger benthic foraminifera are an informal group of protists, grouped together because of their relatively large size and complex internal structure, requiring study using thin-sections. The modern ecological studies of LBF provide a powerful tool with which to develop palaeoecological models for fossil Nummulites (and other symbiont-bearing larger foraminifera in the rock record). A taxonomic revision is proposed, following a "natural" phylogenetical approach based on stratigaphy and morphology, population genetics, ontogenetic variations (recapitulation, acceleration etc, and "décalages chronologiques"). deposition. 2 - A) Stratigraphic log of the section studied in this work with the distribution of se-lected larger benthic fora-minifera. Locally, Paleocene, Eocene, and Oligocene rocks occur in the Concord and Napa areas, and is reported to have been penetrated by wells in the Sonoma area (Hobson, 1971). The F2–3 facies with planktonic, large and small hyaline benthic foraminifers and corallin algal indicate a distal to proximal middle ramp setting. It continued, gradually moving eastward, until the Lower Pliocene. The Jurassic and Cretaceous Franciscian Formation underlies the entire province and is in fault contact with either the overlying Jurassic (Knoxville Formation on the Concord Block) or the Cretaceous (mostly the Upper Cretaceous Great Valley sequence). Large benthic foraminifera are single celled organisms with a calcareous test, or “shell,” which has a complex and often very beautiful internal structure. The basement rocks of both terranes are of Pelagonian origin, exhumed as a multiple tectonic window. ResearchGate has not been able to resolve any citations for this publication.

The Netherlands: 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. 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. depocenter migration Relict HP-LT metamorphic assemblages predating M1 metamorphism are possibly developed during subduction processes and overloading of the obducted ophiolites on the continental margin, characterized the initial stages of deformation. Oligocene to early Miocene sediments deposited between folds display tilted onlap-ping to flat onlapping relationships with the folds. The Jurassic through lower Cretaceous interval is capped by the prominent middle Cretaceous sequence boundary (MCSB). main units are: Basement (U1), Jurassic Tobifera Formation (U2), Early 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. Eocene - Oligocene left-lateral strike-slip faulting along the margin resulted in rifting and source-rock calibration of these ranges against chronostratigraphic standards, and provincialism and endemism. ; Pseudopalmulida emend.

Introduction The deep sea circulation influences the thermal structure of individual oceans, the distribution of deep sea biota and the state of preservation of deep sea sediments. In 1835 Dujardin recognized foraminifera as protozoa and shortly afterward D'Orbigny produced the first classification. gardeners in the oceanic microcosm. 75/76, 1960. Española Micropaleontol. Parts of the eugeosynclinal sequences were folded in the Lower-Middle Eocene and at the Eocene-Oligocene transition. A possible extensional event before D2 may be related to the deposition of the Upper Jurassic-Lower Cretaceous carbonate sediments. miogypsinid. Für den Außen- und Innenbereich verwendbar. Stratigraphic names change frequently, even within the same basin. In the uppermost Missourian and lower Virgilian, most Triticites are medium-sized and evenly biconvex, and have weak septal fluting. 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). Their interpretation as autochthonous is held to be unrealistic on structural and, This investigation was carried out around Silifke, Anamur and Gülnar areas in the Central Taurides where two tectonic units, which tectonically correspond eachother and form a basement to Neogene sequence, were distinguished. These reflections are interpreted to represent siliciclastic turbidite systems deposited as growth and infill strata.

Drooger, C.W., 1993, Radial Foraminifera, morophometrics and evolution. Recently, evidence of more rapid recovery has begun to emerge, suggesting the role of environmental inhibition was previously overestimated. Climatic changes also had little effect upon provinces beyond causing them to expand and contract latitudinally in response to warming and cooling phases. -from Authors, A review of recent advances and problems in the knowledge of larger foraminifera (Lituolacea) of shallow carbonate platforms is presented. Here, we assessed the biochemical and morphological impacts of acidification on the calcification of Amphistegina lessonii and Marginopora vertebralis exposed to different pH conditions. The larger-foraminifera turnover (LFT) during the Paleocene-Eocene transition constitutes an important step in Paleogene larger-foraminifera evolution, involving a rapid increase in species diversity, shell size, and adult dimorphism.

Tectonically-induced eustatic changes, although in no way responsible for provincialism, are the most likely cause of some important changes in the composition of larger foraminiferal faunas during the Cenozoic.-from Authors. Evolution and Geological Significance of Larger Benthic Foraminifera is a comprehensive reference work on the larger benthic foraminifera. together with their American ancestors, at the end of the Burdigalian; a These differently discriminated species seem to demonstrate the reality of the evolutionary processes known as punctuated equilibra and phyletic gradualism, and it is argued that these are but 2 manifestations of a single process and should not be regarded as mutually exclusive. Pennsylvanian, Asturias, N Spain, cf. 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. The new genus exhibits a two-layered wall, inner microgranular and outer hyaline, fibrous and aragonitic, and a planispirally coiled, lenticular test with one lamella for one complete whorl of the deuteroloculus. A correlation between the liassic stages and the biozone of foraminifera is discussed. tectonic and climatic changes determined and constrained in turn the Much slumping occurred during the Cretaceous in the eugeosyncline. We infer that sea level, Wetenschappen, 41: 1À241. in cases of intense recrystallization, are presented. The group has long-proven biostratigraphic value for local and regional correlation, despite uncertainties in their taxonomy, stratigraphic ranges of species, This book aims to introduce rotaliid representatives as index fossils that can be recognized in random thin-sections of cemented rocks. Involutinides originated in Olenekian time from an unknown ancestor. 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. Reviews of the global state of the art of each group are complemented with the new data, and the direct palaeobiogeographic relevance of the new data is analyzed. Middle Miocene sediments continue to infill and onlap the bathymetric relief created by fold formation. The rapid diversification and widespread distribution characterizing the group suggest that The reality of both recapitulation and orthogenesis is reiterated, the latter being regarded as probably responsible for the parallel development shown by some foraminiferal groups in different faunal provinces. Res. The evolutionary lineages of Discocyclina seunesi, Orbitoclypeus multiplicatus and O. bayani are restored for the first time by using the consistent size-increase of the megalospheric embryon that also allowed introducing some new subspecies (Discocyclina seunesi beloslavensis, D. s. karabuekensis, Orbitoclypeus multiplicatus kastamonuensis, O. bayani kurucasileensis and O. munieri ponticus). The abundance of fossil Operculina and closely related genera in climatically relevant periods of geological time such as the Eocene, and the longevity of these large benthic foraminifera, facilitating palaeo-seasonal proxy retrieval (Evans et al., 2013, Evans and Müller, 2013), make this species, and large benthic species in general, deserving of more detailed investigation. Hence, They occur in bioclastic for-algal grainstones and near-reefal rudstones referred to platform margin environments. subfam. Four lineage zones are identified within the Campanian (Zones of O. douvillei, O. tissoti, O. media and O. megaloformis), and two lineage zones are recognized in the Maastrichtian (Zones of O. gruenbachensis and O. apiculata). During the Paleocene to Eocene, intense imbrication of all tectonic units towards SW takes place again (D4). sp., and Wallowaconus oregonensis n. gen., n. Shallow-water carbonates are invaluable archives of past global change. metamorphic processes. and Palaeogene lacustrine source rocks are presently oil and gas generative, which has allowed time for D2 is associated with a M2 metamorphism in low grade greenschist facies conditions. Large benthic foraminifera dominate al., 2003), driving seasonal upwelling at the western the sediment in the inter-reefal part of the shelf, apart side of the Spermonde. Subtle erosional features and rare, slightly mound-ed reflections suggest stacked turbidite systems and reflect the onset of major siliciclastic deposition in the northwestern Gulf of Mexico. It provides documentation of the biostratigraphic ra Paleocene (U5), Eocene (U6), Oligocene (U7), Miocene (U8), and In: Proceedings of the First This is the result of discussions on the subject during a workshop held in Lausanne in October 1989. Larger benthic foraminifera are globally distributed in calcareous temperate to tropical shallow-water environments and are particularly abundant and diverse in coral reefs where they are important calcium carbonate producers supporting reef accretion and substrate stability (Langer et al., 1997, Langer, 2008, Hohenegger, 2006, Fujita et al., 2016, Thissen and Langer, 2017). Birkhäuser, Bâle. influence on the study area. Physiological mechanisms of bleaching were studied on larger benthic foraminifera (LBF) hosting endosymbiotic diatoms. backstripping for the Outer Carpathians sedimentary basins show similarities in the general pattern of their subsidence history. A wider diversity is recorded in the living plankton or Recent sediments that comprise all genera and species described in the literature before 1970. deepening to the south. the Chattian and Aquitanian significant miogypsinid forms evolved in the Most significant fusulinid biostratigraphic changes correlate with major glacio-eustatic cyclothem boundaries, but not all major cyclothem boundaries have significant faunal turnovers. Benthic foraminifera are typically found in fine-grained sediments, where they actively move between layers; however, many species are found on hard rock substrates, attached to seaweeds, or sitting atop the sediment surface. This leads to uncertainties in paleobathymetric estimation, and thus widens error margins of subsidence analysis. In: Cariou, 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. 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. 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. However, there have been few high-resolution taxonomic and ecological studies spanning the full Early and Middle Triassic recovery interval, leaving the precise pattern of recovery and underlying mechanisms poorly constrained. A review of Permian fusuline biostratigraphy is made in this paper in order to improve the correlation of Permian strata globally. Foraminif-eral tests can occur in large numbers, and in many In Pöppelreiter, M.C. facilitated the trans-Atlantic migration of Neorotalia and miogypsinids and the Indo-Pacific in the Burdigalian, coupled with the other global International Conf. By owing the most complete record of Thanetian and early Ypresian orthophragmines from the Western Tethys (using also data from SW France and the Crimean Peninsula) we could reconstruct their early evolution. the potential of trochospirally coiled Involutinina in stratigraphic and paleoenvironmental studies is greatly undervalued. These larger foraminifera are shown in Plate 1. We distinguish six main deformational events (D1-D6). Cahuzac, B., and Poignant, A., 1997, Essai de biozonation de l'Oligo-Miocène dans les bassins européens à l'aide des grands foraminifères The Paikon Massif is regarded as a multiple tectonic window, probably of Pelagonian origin. Larger benthic foraminifera develop characteristically complicated endoskele-tons, which permit the taxa to be accurately identified, even when they are randomly thin-sectioned. Benthic Foraminifera. subord. to the east, the opening of the Drake Passage in the south, and the This study was promoted by the recent efforts using larger benthic foraminiferal (LBF) shells geochemistry for the monitoring of heavy metals (HMs) pollution in the marine environment. water column; others are benthic, living directly on the sea floor or at shallow depths in the sedi-ment (Figure 1). foreland phase is assigned to this time as well as changes in the stress Large textulariids, such as the dictyoconids, are also present in the Paleogene but, along with the nummulitids, are of reduced importance after the end of the Eocene. The most abundance fossils are larger benthic foraminifera. The early Ypresian can be subdivided into the OZ 3 and 4 zones that can be distinguished from each other by different developmental stages of simultaneously running evolutionary lineages such as Discocyclina archiaci, Orbitoclypeus schopeni and O. multiplicatus. Until now, however, it has not been These tectonic units metamorphically, stratigraphically, lithologically and structurally demonstrate different basin origin.
