    The Weichselian Middle Plemglacial fluvial system in the lowlands of northwestern Europe is characterized by quick faciès changes. These faciès are repeated many times during this period resulting in often considerable sequences of alternating peat, sand and loam layers. Consequently, it is impossible to follow individual chronostratigraphic levels by their hthology.Le système fluviatile du Weichselien Pléniglaciaire Moyen des régions basses de l'Europe nord-occidental est caractérisé par des changements rapides de faciès qui se répètent plusieurs fois. Cela a abouti à des séquences parfois considérables de couches de tourbe, de limon et de sable. Par conséquent il est impossible de poursuivre des niveaux chronostratigraphiques individuels par leur lithologie.Vandenberghe Jef.

    BHALLA-CLEENEWERCK JOURNAL EFFICIENCY FACTOR, BC-JEF©-A NOVEL AUTHOR-CENTRIC METRIC FOR JOURNAL EFFICIENCY

    No full text
    According to English definition, “efficiency” is the state or the quality of being able to accomplish something with the least waste of time and effort. Concerning the Journals, “efficiency” signifies providing the submitting authors with a peer-review decision with a least loss of time and academic value. The “efficiency”, on the journal’s part, also means least delays in academic returns that submitting authors deserve from their own work. The “efficiency”, on the journal’s part, also implies least delays in making available the access to possible benefits to the patients or public from the author’s work. In other words, efficiency is a measurable ability of the journals, whether paid or unpaid, to do their “duties well”, “efficiently”, “successfully”, and “without waste and avoidable loss” to the submitting authors. It is our vision to make the entire publication process coherent and convenient. At the same time, it is also our vision to guard the rights of submitting authors in having a time-bound, convenient, and efficient service with high customer service values from their service providers, i.e. the journals, whether paid or unpaid. For this, we introduce “Bhalla-Cleenewerck Journal Efficiency Factor (BC-JEF©)”, named in short as JEF©, as a parameter for assessing the functional efficiency of the journals. We introduce JEF©, an innovative non-profit measure to ensure the “greater good” of all concerned. For the journals, JEF© would help them recognize their duties and obligations for providing an efficient publication service to the authors. Also, JEF© would facilitate the journals in making their publication process more fulfilling and coherent, particularly for the authors, based on whom they thrive. JEF© would also help the journals in their healthy commercial competition. For the authors, JEF© would help them make an informed choice while submitting their work to a journal. For other agencies, JEF© provides them with an alternative metric to track parameters that are not being covered by any of the current existing journal metrics.

It operates under the authority of the only global and treaty-based intergovernmental university in the world (EUCLID), with other intergovernmental organizations in mind. Currently, there are more than 17,000 universities globally, but less than 15 are multilateral institutions, EUCLID, as IRPJ's sponsor, is the only global and multi-disciplinary UN-registered treaty-based institution. IRPJ authors can be assured that their research will be widely visible on account of the trusted Internet visibility of its ".int" domain which virtually guarantees first page results on matching keywords (.int domains are only assigned by IANA to vetted treaty-based organizations and are recognized as trusted authorities by search engines). In addition to its ".int" domain, IRPJ is published under an approved ISSN for intergovernmental organizations ("international publisher") status (also used by United Nations, World Bank, European Space Agency, etc.). IRPJ offers: United Nations Treaty reference on your published article (PDF) "Efficiency" driven and "author-focused" workflow Operates the very unique author-centric metric of "Journal Efficiency Factor" Minimal processing fee with the possibility of waiver Dedicated editors to work with graduate and doctoral students Continuous publication i.e., publication of articles immediately upon acceptance The expected time frame from submission to publication is up to 40 calendar days Broad thematic categories Every published article will receive a DOI from Crossref and is archived by CLOCKSS.

    La stratigraphie et la genèse de dépôts pléistocènes à Goirle (Pays-Bas)

    Sediments of various fluvial origins (bed deposits, alluvial fan deposits, etc ) have been locally reworked by runoff or by aeolian activity. They are overlain by a Late Eemian peat. The heavy mineral association of the Pre-Eemian deposits show the characteristics of the subsoil from which they were eroded. In the overlying Weichselian deposits aeolian processes were dominating. Besides superficially reworked layers, three series of aeolian deposits may be distinguished : loamy coversands with typical horizontal lamination, (sandy) loams with the characteristic lœss-properties and loamless sands of local origin. These sediments show a heavy mineral association of mixed stable and unstable composition. During the Weichselian two periods with permafrost conditions can be recognized by the occurrence of two distinct levels of ice-wedge casts associated with overlying involutions of high amplitude.Des sédiments pre-Eemiens d'origine fluviatile variée sont remaniés localement par le ruissellement et par le vent. L'association des minéraux lourds montre les mêmes caractéristiques que ceux du substrat érodé. Ces dépôts inférieurs se trouvent sous une tourbe fini-Eemienne. Dans la série supérieure Weichsélienne les processus éoliens dominent. En dehors de quelques couches légèrement remaniées, trois catégories de sédiments éoliens peuvent être distinguées : des sables de couverture limoneux à lamination horizontale typique, des limons (sableux) à caractère lœssique et des sables de formation plus locale. Cette série supérieure est caractérisée par une association mixte de minéraux stables et instables. Deux phases à pergélisol, datant du Weichsélien, se manifestent par la présence de deux niveaux de fentes de glace comblées surmontées de cryoturbations à grande amplitude.Vandenberghe Jef, Krook Leen.

    The Weichselian Late Glacial in a small lowland valley (Mark River, Belgium and The Netherlands) [Le Weichselien tardiglaciaire dans une vallée des plaines basses (La rivière Mark, Belgique et Pays-Bas)]

    A meandering pattern and a steep incision is the reaction of the Mark river, as well as many European river systems, to changing conditions of climate and vegetation cover at the start of the Late Glacial. The maximum incision is reached between 1 1 780 and 1 1 920 yr. B.P. It has induced lowering of the water table resulting in increased eolian activity. This period corresponds to the Older Dryas which is characterized by dry soil conditions and not by changed climatic conditions. River accumulation started from that time on and continued during the Allerod, Younger Dryas and Holocene. The paleobotanical record is strongly dependent on the geomorphological position in the river basin.La rivière Mark a, comme beaucoup d'autres rivières européennes, établi un cours à méandres profondément entaillés au début du Tardiglaciaire par suite des changements du climat et de la couverture végétale. L'incision maximale a été atteint entre 11 780 B.P. et 11 920 B.P. Cela a donné lieu à un abaissement du niveau phréatique et de ce fait à une reprise de l'activité éolienne. Cette période correspond au Dryas Ancien qui est caractérisé par un assèchement du sol et pas par des changements climatiques. L'accumulation fluviatile commençait dès cette période et continuait pendant l'Alleröd, le Dryas Récent et l'Holocène. L'enregistrement paléobotanique dépend considérablement de la position géomorphologique dans le bassin fluviatile.Vandenberghe Jef, Bohncke Sjoerd.

    The Sound of ”Quaternary”

    No full text
    It is useful to re-consider at specific times the strategy of a journal. Some thoughts are expressed here at the occasion of the renewal of the editorship of ”Quaternary”. No changes are envisaged in the multidisciplinary character of the journal. In addition, it is felt necessary to increasingly attract the creative input from underrepresented researchers in Quaternary science (e.g., young scientists, female scientists, scientists from weakly developed countries)
