VVarm-water foraminifer assemblages Indicate that the area of the Polish Low­ lands have been situated within the extend of Influences of the Mediterranean • province In the Priabonian. The paper presents a first attempt to summarize the avaUable data on Influences of that province In the extra-Carpathian Poland. The stratigraphic setting of the described species and ecological and bathymetric con­ ditions In the basin are reconstructed on the basis of comparisons with coeval assemblages of the same type from other countries and correlation with nanno­ plankton datlngs. The migration of warm water species from areas adjoining the Carpathian geosyncline far to the north are explained as due to tectonic pulses of the Pyrenean phase of the Alpine orogeny. The foraminifer microfauna ap­ pears clearly different In character from the coeval one from Northern Poland (Leba Elevation and Puck Embayment).

INTRODUCTION The litho- and biostratigraphy of Paleogene strata from the Fore-Su­ detic Monocline and Kujawy area have been studied by several authors including Dyjor (1970, 1974, 1978), Pozaryski (1954), MatI and Smigielska (1977), Odrzywolska-Bienkowa (1966, 1973, 1975), Cimaszewski (1964) and Ciuk (1967). However, microfauna remained unknown from these regions. The present paper is aimed at filling up that gap as 'well as to emphasize the recorded influences of the Mediterranean paleobiogeographic province. The studied material comes from the Geological Institute boreholes Sieroszowice, Miech6w, Globice, Izbica Kujawska, Lanieta and Augusty­ nowo. Mor,eover, S. Dyjor (Lower Silesian Branch of the Geological Insti­ tut , Wrodaw) kindly supplied material from the boreholes Kur6w Maly and Jerzmanowa. In that material, there were found 87 foraminifers spec- 110 E WA ODRZYWOLSKA-BIE~KOWA & KRYSTYNA POZARYSKA manowa Eocene Beds - for mudstone-carbonate rocks from the Glog6w­ Jerzmanowa area. Rocks from the top of the sequence, yielding Oligocene elements, he assigned to the Lubuska Series, characterized by predomin­ ance of sandy facies on the carbonate, Odrzywolska-Bieilkowa (1972). CHARACTERISTICS OF FORAMINIFER ASSEMBLAGES Shallow- and warm-water assemblages of foraminifer microfauna, found in the Fore-Sudetic Monocline, Kujawy and Mazowsze regions, are surprisingly close to those described from the Upper Schonewalde Beds of the so-called Calau type in the GDR , described by Kiesel (1970). Both in the Polish Lowlands and GDR, strata yielding shallow-and warm-water microfauna occur _in patches, due to pre-Oligocene emersion and erosion which has taken place between the Oligocene and Pleistocene (Lotsch 1967). The omnipresent components of the assemblages "from the Polish Lowlands and GDR include the genera Articulina, Vertebralina, Reussella, Discorbis, Biapertorbis (sensu Pokorny), Planorbulina, Spiroloculina, Rhapydionina which are unknown in basins of the boreal type. In turn typical boreal species Astccolus decorata Reuss, Bulimina aksuatica Mo­ rozo va , Brizalina antegressa Subbotina and Eoeponidella lucida (Minako­ va) are missing'r Kiesel and Lotsch (1963) were first to state that Upper Eocene warm-water assemblages sometimes comprise few species but very numerous individuals, calling them "F ast-Monofaunen". In Poland, this phenomenon is especially well expressed in the assemblages from the borehole columns Augustynowo and Izbica Kujawska, mainly compos­ ed of representatives of the genera Asterig erina, Pararotalia, V ertebralina and Reu ssella. Kiesel and Lotsch (1963) explain that phenomenon in terms of specific ecolo gical conditions in littoral and sublittoral zones, favour­ able for symbiosis of foraminifers and algae requiring shallow and well illuminated water. The tests of nummulitids and some small-sized foraminifers occurring in Priabonian rocks from the top of salt domes at Lanieta and Augustyno­ wo are often damaged. Th at may be due to tectonic deformations related to halokinetic processes. In the USSR, assemblages similar to those described here have been found in both European and Asiatic parts. Large monographic studies of that microfauna were published by Tutkovskij (1925), Kaptarenko-Tscher­ nousova (1951, 1956), Morozova (1949), Samojlova (1947), Chalilov (1948), Kraeva and Zerneckij (1969) and others. According to Bettenstaedt (1949), migration of warm-water Upper Eocene (Pr iabonian) forms to areas situated at fairly large distances north of those directly adjoining the Alpine region were made possible due to OC CURRENCE U 5 5 R .~'" > c .~ '" .

  • Palaeogene Marine Stratigraphy in China
    LETHAIA REVIEW Palaeogene marine stratigraphy in China XIAOQIAO WAN, TIAN JIANG, YIYI ZHANG, DANGPENG XI AND GUOBIAO LI Wan, X., Jiang, T., Zhang, Y., Xi, D. & Li G. 2014: Palaeogene marine stratigraphy in China. Lethaia, Vol. 47, pp. 297–308. Palaeogene deposits are widespread in China and are potential sequences for locating stage boundaries. Most strata are non-marine origin, but marine sediments are well exposed in Tibet, the Tarim Basin of Xinjiang, and the continental margin of East China Sea. Among them, the Tibetan Tethys can be recognized as a dominant marine area, including the Indian-margin strata of the northern Tethys Himalaya and Asian- margin strata of the Gangdese forearc basin. Continuous sequences are preserved in the Gamba–Tingri Basin of the north margin of the Indian Plate, where the Palaeogene sequence is divided into the Jidula, Zongpu, Zhepure and Zongpubei formations. Here, the marine sequence ranges from Danian to middle Priabonian (66–35 ma), and the stage boundaries are identified mostly by larger foraminiferal assemblages. The Paleocene/Eocene boundary is found between the Zongpu and Zhepure forma- tions. The uppermost marine beds are from the top of the Zongpubei Formation (~35 ma), marking the end of Indian and Asian collision. In addition, the marine beds crop out along both sides of the Yarlong Zangbo Suture, where they show a deeper marine facies, yielding rich radiolarian fossils of Paleocene and Eocene. The Tarim Basin of Xinjiang is another important area of marine deposition. Here, marine Palae- ogene strata are well exposed in the Southwest Tarim Depression and Kuqa Depres- sion.

The section covers almost the entire Lutetian and ranges into the Priabonian. It is part of the Helvetic (tectonic) Unit and represents the sedimentary processes that took place on the southern shelf to upper bathyal of the European platform at that time. Six lithologic units occur in the Adelholzen-Section: 1) marly, glauconitic sands with predominantly Assilina, 2) marly bioclastic sands with predominantly Nummulites, 3) glauconitic sands, 4) marls with Discocyclina, 5) marly brown sand. These units were combined as “Adelholzener Schichten” and can be allocated to the Kressenberg Formation.

Here we studied new fossil chondrichthyans from two localities, Río de Las Minas, and Sierra Dorotea, both in the Magallanes Region, southernmost Chile. In Río de Las Minas, the upper section of the Priabonian Loreto Formation have yielded material referable to the taxa Megascyliorhinus sp., Pristiophorus sp., Rhinoptera sp., and Callorhinchus sp. In Sierra Dorotea, middle-to-late Eocene levels of the Río Turbio Formation have provided teeth referable to the taxa Striatolamia macrota (Agassiz), Palaeohypotodus rutoti (Winkler), Squalus aff. weltoni Long, Carcharias sp., Paraorthacodus sp., Rhinoptera sp., and indeterminate Myliobatids. These new records show the presence of common chondrichtyan diversity along most of the Magallanes Basin. The new record of Paraorthacodus sp. and P. rutoti, support the extension of their respective biochrons in the Magallanes Basin and likely in the southeastern Pacific.

    Netherlands Journal of Geosciences / Geologie en Mijnbouw 83 (3): 179-185 (2004) A rapid clay-mineral change in the earliest Priabonian of the North Sea Basin? R. Saeys, A. Verheyen & N. Vandenberghe1 K.U. Leuven, Historical Geology, Redingenstraat 16, B-3000 Leuven, Belgium 1 corresponding author: [email protected] Manuscript received: February 2004; accepted: August 2004 Abstract In the Eocene to Oligocene transitional strata in Belgium, clay mineral associations vary in response to the climatic evolution and to tectonic pulses. Decreasing smectite to illite ratios and the systematic occurrence of illite-smectite irregular interlayers are consequences of a cooling climate. A marked increase in kaolinite content occurs just after a major unconformity formed at the Bartonian/Priabonian boundary and consequently is interpreted as resulting from the breakdown of uplifted saprolites.

The oldest dikes are exposed on Hurd Peninsula (Livingston Island) and do not yield 40Ar/39Ar plateaux. Our best estimates suggest dike intrusion at about the Cretaceous/Paleogene boundary. An older age limit for the dikes is established by Campanian nannofossil ages from their metasedimentary host. Dike intrusion began earlier and lasted longer on Hurd Peninsula (Danian to Priabonian) than on King George Island (Thanetian to Lutetian). Arc magmatism on King George Island, possibly accompanied also by hypabyssal intrusions, began in the Cretaceous as indicated by ages from the stratiform volcanic sequence. The dikes on King George Island were emplaced beginning in the late Paleocene and ending 47–45 Ma. The youngest arc-related dikes on Hurd Peninsula were emplaced ~37 Ma. Citation: Kraus, S., M.

Cad., No. 86, 06520 Söğütözü, Ankara, Turkey ABS TRACT The Eocene shallow marine deposits marking the first marine incursion in the Biga Peninsula (NW Turkey) after the collision of the Sakarya and Anatolide-Tauride plates were investigated based on paleontological, litho- and chrono-stratigraphic data. Larger Benthic Foraminifera (LBF) from patchily distributed outcrops were studied in order to i) revise the stratigraphy of Eocene shallow marine units, and ii) establish a modern biostratigraphic setting and a correlation scheme. The Şevketiye Formation (Fm.) is herein defined as a predominantly shallow marine clastic deposit with subordinate carbonates overlying the Çamlıca metamorphic rocks, and passing laterally to the Soğucak Fm., a carbonate unit that is widely represented in the Thrace Basin. The record of alveolinids, primitive developmental stages of heterosteginids, and orthophragminids in the Şevketiye Fm. suggests that this formation is part of the Shallow Benthic Zones (SBZ) 16?/17 (Late Lutetian?/Early Bartonian), SBZ17?/18 and SBZ19A (Early Bartonian/earliest Priabonian).

    Netherlands Journal of Geosciences / Geologie en Mijnbouw 83 (3): 241-248 (2004) The Rupelian-Chattian boundary in the North Sea Basin and its calibration to the international time-scale S.Van Simaeys Historical Geology, University of Leuven, Redingenstraat 16, B-3000 Leuven, Belgium.

E-mail: [email protected] Manuscript received: February 2004; accepted: August 2004 •N G Abstract The classical problem of the nature and age of the Rupelian-Chattian (Early-Late Oligocene) unconformity in its type region is here approached using organic walled dinoflagellate cyst (dinocyst) correlations between the North Sea Basin and well- calibrated central Italian (Tethyan Ocean) sections. Useful Oligocene dinocyst events are the last occurrence of Enneadocysta pectiniformis (~29.3 Ma), and the first occurrences of Saturnodinium pansum (~29.4 Ma), Distatodinium biffii (~27.9 Ma) and Artemtsiocysta dadodichotoma (~26.7 Ma).The latter event marks the earliest Chattian.The improved correlations indicate that the Rupelian-Chattian (R-C) boundary is associated with the so-called 'Oligocene Glacial Maximum'. This phase of important global cooling and glacio-eustatic sea level fall is genetically related to die unconformity between the classic Oligocene stages. Subsequent global warming (so-called 'Late Oligocene Warming Event'), induced a major sea level rise, leading e.g. to the time-transgressive deposition of the typical basal Chattian glauconitic sands. The oldest of die Chattian units have a GPTS age of-26.7 Ma. It further appears that a hiatus of ~500 kyrs spans the classic Rupelian-Chattian unconformity. Keywords: biochronostratigraphy, dinoflagellate cysts, North Sea Basin, Rupelian-Chattian boundary, Tethyan Ocean Introduction R-C GSSP ideally should coincide with the base of the classic Chattian Stage, stressing the importance of The Oligocene successions of the southern North Sea its characterisation.
