Review of the stratigraphy of the Ordovician in the Brabant Massif, Belgium

A review of isolated data from the literature and our own observations make it possible to establish a model of the stratigraphical history of the Ordovician on the southern margin of the Brabant Massif. The succession is composed of seven informal formations, totalling a minimum of 2500 m of sediments, mainly comprising mudstones, siltstones and sandstones. This succession is compared and partly correlated with the sections observed in the adjoining areas, in the Bande de Sambre-et-Meuse, the Stavelot and Rocroi Massifs and the Remscheid–Altena and Ebbe anticlines (western Germany). © 1993, Cambridge University Press.

Les microfossiles (Chitinozoaires et Acritarches) des schistes du Tazekka au Maroc oriental

Die Schiefer vorn Tazekka-Massiv (Marokko) die bis jetzt als Unter-Karbon galten, haben Acritarchen und Chitinozoen des unteren Ordoviz (Arenig-Llanvirn) geliefert (Rauscher et al., 1982). Die wichtigsten dieser Mikrofossilien werden hier beschrieben und abgebildet.Acritarchs and Chitinozoans of Lower Ordovician age (Arenigian-Llanvirnian) were found in the schists of the Tazekka (Morocco), previously dated on the Lower Carboniferous (Rauscher et al., 1982). These microfossils are described and illustrated here.Marhoumi Mohamed-Rachid, Rauscher Raymond, Vanguestaine Michel.

Technologie des anneaux en schiste dans le groupe de Blicquy/Villeneuve-Saint-Germain à Vaux-et-Borset (Hesbaye, Belgique) : interférences de sous-systèmes techniques

The Blicquy/Villeneuve-Saint-Germain settlement of Vaux-et-Borset (Liege province, Belgium) has produced a remarkable corpus of material relating to the manufacture of schist rings. The data are of considerable importance in terms of both quantity and quality. Through a typo-technological study it is possible to distinguish the various manufacturing sequences employed. Using these results, the authors have undertaken a programme of experimental study and microscopic analysis on both archaeological and experimental artefacts, with a view to reconstructing the know-how and the tools (flint, sandstone and schist) involved in the different stages of working this soft stone. These studies lead to the formulation of major hypotheses on the importance of the schist technical subsystem in the definition of the Blicquy /Villeneuve-Saint-Germain group at Vaux-et- Borset.Le village du groupe de Blicquy/Villeneuve-Saint-Germain de Vaux-et-Borset (province de Liège, Belgique) a livré un corpus remarquable de vestiges issus de la fabrication ď anneaux en schiste. Cet ensemble documentaire s'est révélé très pertinent numériquement et qualitativement. L'étude typotechnologique a permis de différencier les schémas opératoires des fabrications mises en oeuvre. A partir de ces résultats, les auteurs ont mené un programme d'analyses expérimentales et microscopiques combinées sur les pièces archéologiques et expérimentales portant sur la reconstitution des savoir-faire et des dispositifs instrumentaux (outils en silex, en grès et en schiste) impliqués dans cet artisanat de la pierre tendre, aux différentes étapes de sa réalisation. Ces travaux aboutissent à la formulation d'hypothèses conséquentes concernant la spécificité du sous-système technique du travail du schiste dans la définition de l'industrie du groupe de Blicquy /Villeneuve Saint -Germain à Vaux-et-Borset.Burnez-Lanotte Laurence, Caspar Jean-Paul, Vanguestaine Michel.

A new geological map of the Brabant Massif, Belgium

A new geological map, mostly subcrop, of the Brabant Massif is presented, based on a revised lithostratigraphy of the outcrop area and on recently acquired palaeontological and lithological data from boreholes in the concealed area. New interpretations of magnetic and gravity data are used to extend the lithostratigraphical units into areas with few or no boreholes. A structural model of the western, northern and southern parts of the Brabant Massif is presented. The main anticlinal axis plunges towards the west-northwest, its core comprising Upper Precambrian (?) to Lower Cambrian terrigenous rocks which outcrop in the southeast. To the north of the main axis, younger rocks appear in regular succession, but to the southwest this picture is complicated by the occurrence of a second anticlinal structure and by a subparallel magmatic arc. © 1993, Cambridge University Press.
