  • A New Lithostratigraphic Scale for the Palaeogene of Belgium
    Bulletin de la Société belge de Géologie, T. 102 (1-2), 1993, pp. 215-229. Bulletin van de Belgische Vereniging voor Geologie. Ed. 1994 A NEW LITHOSTRATIGRAPHIC SCALE FOR THE PALAEOGENE OF BELGIUM by R. MARECHAL' ABSTRACT The study of the Belgian Tertiary started more than 150 years ago. Since that time such an enormous amount of data has been gathered, that the commission in charge of the revision of the stratigraphic scale of the Belgian Tertiary decided to limit its activity to the elaboration of a lithostratigraphic scale according to the rules of the IUGS International Subcommission on Stratigraphic Classification. The fundamental unit of such a classification system is the Formation and therefore much attention has been given to Formation names. Some of these names are in use since a very long time, others are new. Preference has been given to names of well known localities situated within the main outcrop areas of the Formation under consideration. Formations may be completely or partially subdivided into Members or may remain undivided. Member names have been selected according the same rules as Formation names. Since members are mostly homogeneous in lithology the Member name may be followed by a rock or sediment name (Vlierzele sand, Asse clay). Most formations have been assembled into Groups. Group names should be considered as tentative. It is questionable whether an internationally admitted chronostratigraphic name (Rupelian, Ypresian) may also be used as a Group name (Rupel, Ieper). The efforts of the National Commission for Stratigraphy of the Tertiary resulted in a proposal for a lithostratigraphic scale for the Palaeogene, which was distributed to a limited number of persons in 1988 and discussed consecutively.

This study aims to characterize Belgian clays in order to evaluate their use for manufacture of compressed earth blocks (CEB). Nineteen Belgian clay deposits were sampled in 56 sites and 135 samples were collected and analyzed. The analyses focus on the determination of particle size, plasticity, nature and mineralogy as the main characteristics for assessing the suitability of the raw clays to make CEB. These analyses allow for classifying the sampled clay deposits in three categories: clays that can be used unchanged to make CEB (2 clay deposits), clays that are suitable for the manufacture of CEB but require addition of sand and gravel particles (13 clay deposits) and clays that are suitable for the manufacture of CEB if they are mixed with other raw clays (4 clay deposits). In order to verify the use of these clays, five of them served as a model for making CEB. The strength of these bricks was evaluated by testing for compressive strength and abrasion resistance. The results of these tests confirm the suitability or not of the sampled clays for the manufacture of CEB.

  • The Composite Kortrijk Section (W Belgium): a Key Reference for Mid-Ypresian (Early Eocene) Stratigraphy in the Southern North S
    GEOLOGICA BELGICA (2017) 20/3-4: 125-159 The composite Kortrijk section (W Belgium): a key reference for mid-Ypresian (Early Eocene) stratigraphy in the southern North Sea Basin Etienne STEURBAUT1 & Chris KING2† 1 Royal Belgian Institute of Natural Sciences, Operational Directory Earth and History of Life, Vautierstraat 29, B-1000 Brussels and KU Leuven, Belgium; [email protected] 2† Chris King sadly passed away while this paper was in its final stage. It is dedicated to his memory, in recognition of his lifetime achievements in stratigraphy and biostratigraphy and to his great love and fascination for the Ypresian strata of Belgium. ABSTRACT. The upper part of the Kortrijk Clay Formation (the Roubaix Clay and Aalbeke Clay Members of mid-Ypresian age) has been exposed in road and canal cuttings and clay quarries in the Kortrijk area (western Belgium), and penetrated by several cored boreholes. It is overlain disconformably by the Mont-Panisel Sand Member of the Hyon Sand Formation (upper middle Ypresian). The Roubaix Clay Member contains diverse and well-preserved calcareous nannofossils, dinoflagellate cysts, foraminifera, ostracods and other calcitic microfossils, and less well-preserved mollusc assemblages, while the Aalbeke Clay Member is secondarily decalcified. The calcareous nannofossil subdivision of upper NP11 and lower NP12 has been recognised in the Kortrijk area, and calibrated with the NW European mid-Ypresian dinoflagellate cyst, ostracod and planktonic foraminiferal zones and datums (e.g. Subbotina influx). Several medium-scale depositional sequences, with an estimated duration of 400 kyr or less, have been recorded. Their respective boundaries coincide with the resistivity maxima identified on the majority of the wireline log profiles of the Belgian Ypresian.

  • 5 Geology and Lithostratigraphy
    Geothermal Exploration Well Mol-GT-01(-S1) Final Wellsite Geological Report 5 Geology and Lithostratigraphy 5.1 Introduction The mudlogging services were provided by GeoService GmbH. Lithological descriptions commenced from the start of the 24” section at 34m with the first sample taken at 40m. Hydrocarbon indications are presented in chapter 6 of this report. The cuttings descriptions made by the Wellsite Geologist are presented in appendix B. The presence of the Wellsite Geologist was however mainly limited to picking casing and coring points. For the remainder of the sample descriptions refer to the daily mudlogging reports by GeoService. Some samples were also collected by Smet during drilling of the conductor to 34m. All formation boundaries are referenced to ground level (mMDBGL). Final formation tops were picked based on the wireline Gamma Ray from run A2, B1, D1 and E1. Only in the 12¼” section tops were based on the memory LWD Gamma Ray data as there was a depth stretch error in wireline run C1 recorded by BLM. During drilling real-time LWD-GR was used for correlation in all sections. For the Tertiary formations down to the Chalk Group, the Mol-1 well was used for reference and for the deeper sections, the well was correlated with the Merksplas and Poederlee wells. The stratigraphic scheme utilised in this report follows the Lithostratigraphic scale of Belgium, Geologica Belgica, Vol. 4 (2001), Nr. 1-2 with additional reference from the National Stratigraphic Commission Belgium ( http://natstratcommbelgium.drupalgardens.com/ ). Also the 2 papers on Belgian stratigraphy by B. Laenen (2002) were used as reference.

Abstract Palynological investigation (dinoflagellate cysts and fungal remains) of 155 samples from the two subsurface sections and three outcrop of the Middle-Upper Eocene siliciclastic-carbonate platform facies of the Jarillal, Pauji and Caus formations of the Eastern Zulia yield a total of 60 species of dinoflagellate cysts, 42 species of fungal remains, freshwater protists and acritarchs, and numerous phytoclasts. Five new species of fungal remains are described. By means of characteristic dinoflagellate cysts, four assemblages zones were defined which led to the stratigraphic division of the profiles. Comparative research on the stratigraphic distribution of Middle Eocene dinoflagellates in different geographical areas not only confirmed the stratigraphic distribution but also extended their stratigraphic range. This extension applies mainly to the dinocysts Polysphaeridium subtile and Areoligera senonensis. Therefore, their significance as a stratigraphic marker is limited. The composition of the terrestrial palynoflora (fungal remains) is indicated of a general warm and climatic humid conditions during the Middle-Upper Eocene.

The group includes four formational units: the Mortemer (Mortemer Limestone), the Vaugirard (Plastic Clay), the Soissonnais (Lignitic Clay of Soissons) and Epernay (Lignitic Clay of Epernay) formations and associated members. An integration of charophyte, dinoflagellate cyst and, to a lesser extent, calcareous nannoplankton biostratigraphy allows us to place the succession in an approximate, integrated biostratigraphic framework. Our introduction of a formal lithostratigraphic framework for the Upper Paleocene-Lower Eocene succession in the Paris Basin contributes to emphasize the distinctiveness of the Sparnacian deposits as an independent stratigraphic unit.

  • And Sequence Analysis of West Belgian Eocene Continental Shelf Deposits
    314 Zbl. Geol. Paläont. Teil I 1990 H. 8 931-955 Stuttgart, März 1991 Grain size-, facies- and sequence analysis of West Belgian Eocene continental shelf deposits By PATRIC JACOBS, ERWIN SEVENS, MARC DE BATIST and JEAN-PIERRE HENRIET With 14 figures and 2 tables in the text JACOBS, P., SEVENS, E., DE BATIST, M. & HENRIET, J.-P. (1991): Grain size-, facies- and sequence analysis of West Belgian Eocene continental shelf deposits. - Zbl. Geol. Paläont. Teil I, 1990 (8): 931-955; Stuttgart. Abstract: Grain size trends and sedimentary structures of Eocene conti­ nental shelf deposits from offshore and onshore drillings in West Belgium were combined for reconstruction of depositional environments. The VAIL-model for siliciclastic sedimentation on shelf margins allows systems tracts identification on basis of grain size signals. The (put into revision) Eocene lithostratigraphy could therefore be transferred into sequence stratigraphy. Sediment genetic interpretation of sedimentary structures and grain size trends, together with sediment supply indications, suggest a Pre- Rhine-Meuse-Scheldt delta high on the shelf as depositional system. K e y words: Korngrößentrend, Faziesanalyse, Sequenzstratigraphie, Kontinentalschelfablagerungen, Eozän, Westbelgien. Kurzfassung: Trends der Korngrößenverteilung und das Sedimentgefüge von eozänen Kontinentalschelfablagerungen aus "offshore"- und "onshore"- Bohrungen in Westbelgien werden kombiniert, um das Ablagerungsmilieu zu rekonstruieren. Das VAIL-Modell für die siliziklastische Sedimentation am Schelfrand dient zur Identifizierung von Sedimentgenerationen aufgrund ihres Korn­ größensignals. Dadurch ist es möglich, die (geänderte) Eozän-Lithostrati­ graphie in die Sequenzstratigraphie zu übersetzen. Sediment genetische Interpretationen von Sedimentgefügen und Korn­ größenverteilungen, zusammen mit Indikatoren der Sedimentherkunft, lassen auf ein hoch am Schelf gelegenes Prä-Rhein-Maas-Schelde-Delta als Ablagerungssystem schließen.
