Geology of the Ardenne Anticlinorium, in the Amberloup - La Roche-En-Ardenne - Houffalize Sector
GEOLOGICA BELGICA (2013) 16/3: 196-205 Geology of the Ardenne Anticlinorium, in the Amberloup - La Roche-en-Ardenne - Houffalize sector. The faults of the La Roche Syncline and the overturned Taverneux Anticline. Léon Dejonghe Royal Institute of Natural Sciences, Geological Survey of Belgium, 13 rue Jenner, B-1000 Bruxelles. E-mail: leon.dejonghe@ naturalsciences.be Abstract. The area included in the Amberloup - La Roche-en-Ardenne - Houffalize sector is located in the province of Luxembourg and belongs geographically to the Central Ardenne. The rocks are of Lower Devonian age. On the regional level, the region integrates southeast of the axial zone of the Ardenne Anticlinorium, northwest of the Neufchâteau Synclinorium. Geological mapping at the scale of 1 : 10 000 has identified numerous faults ignored on old geological maps at a scale of 1 : 40 000. The greater part of map-sheet Houffalize is modeled by the Houffalize Syncline, which extends into the lower third of map-sheet Wibrin. The detailed surveys of its northern flank and the transition zone to the La Roche Syncline in the northwest show that the intermediate structure does not correspond to a simple anticline known in the literature as Taverneux Anticline. During the Variscan orogeny, an anticline was effectively formed, then it overturned north and, finally, was segmented by longitudinal faults which, initially, were reverse faults, but some were reactivated as normal faults during a phase of relaxation. Keywords : Stratigraphy, Lower Devonian, Variscan orogeny, fault, cleavage, geological mapping. Résumé.

The Sand Filterers
1 The sand filterers Majnoun, the passionate lover of Leila, wandering in the desert, was seen one day filtering sand in his hands. “What are you looking for?” He was asked. “I am looking for Leila.” “How can you expect to find such a pure pearl like Leila in this dust?” “I look for Leila everywhere”, replied Majnoun, “hoping to find her one day, somewhere.” Farid Eddin Attar, as reported by Emile Dermenghem, Spiritual Masters’ Collection. 2 Introduction Whatever judgment passed in the future on Mostefa Ben Boulaid, Bachir Chihani or Adjel Adjoul, a place in the mythical Algerian revolution will be devoted to them. Many controversies will arise concerning the nature of this place. As for me, I only hope to be faithful to their truth. To achieve this, I think time has come to unveil the history of the Aures- Nememcha insurrection and rid it of its slag, reaching deep in its genuine reality which makes it fascinating. The events told here go from November 1st, 1954 to June 1959. They depict rather normal facts, sometimes mean, often grandiose, and men who discover their humanity and whose everyday life in the bush is scrutinized as if by a scanner. As it is known, it is not easy to revive part of contemporary History, particularly the one concerning the Aures Nememcha insurrection of November 1954. I have started gleaning testimonies in 1969, leaving aside those dealing with propaganda or exonerating partiality. I have confronted facts and witnesses, through an unyielding search for truth, bearing in mind that each witness, consciously or not, is victim of his own implication. -

C. MATTHEWS t (*) In Memoriam On May Sth, 1983, Dr. S. C. MATTHEWS died suddenly. A few days before he sent us the manuscript of the talk he was expected to give at the meeting that the Société belge de Géologie organized to honour their Fast-President and General-Secretaries Ir. A. DELMER et Dr. R. LEGRAND. Unfortunately, because of ill ness, he was unable to attend the whole meeting and did not pre sent his contribution. S. C. MATTHEWS was born at Muirkirk {Scotland) on 23rd May, 1936. He first attended Glasgow University were he got his B. Sc. Then he was awarded a Shell Studentship and proceeded to the University of Bristol, where he first became Assistant Lecturer in 1960 and was promoted Lecturer in 1963. He got his Ph. D. in 1965. He left the University of Bristol in 1982 for the Department of Paleobiology of the University of Uppsala {Sweden) where he died suddenly and unexpectedly following a heart attack. His scientific carrer was quite eclect:ic andproductive. Indeed, he managed with equal mastery work in three different fields : - Devonian and Carboniferous conodont faunas, mainly in Southwest England; - Studies of early Cambrian skeletal fossils.. This involving exploration of some of the earliest examples of mineralized organic tissues; - Geology of the southwestern part of the British Isles in its Eurooean context. -
The Essential Role of Isotopes in Studies of Water Resources
The Essential Role of Isotopes in Studies of Water Resources One of the prerequisites for efficient management of a water resource is reliable information about the quantity, flow and circulation of water within the resource that is being exploited. During the past two decades, isotope techniques have come to play a major role in the qualitative and quantitative assessment of water resources. In studies of surface water, isotope techniques are used to measure water runoff from rain and snow, flow rates of streams and rivers, leakage from lakes, reservoirs and canals and the dynamics of various bodies of water. Studies of groundwater resources (springs, wells) today are virtually unthinkable without isotope techniques. Basically, these techniques are simple and relatively quick. Among the many questions which may be asked of hydrologists about a given groundwater supply, often the most critical one concerns the safe yield so that the source will not run dry, or for a source to be "mined", the total yield. Isotope techniques can be used to solve such problems as: identification of the origin of groundwater, determination of its age, flow velocity and direction, interrelations between surface waters and groundwaters, possible connections between different aquifers, local porosity, transmissivity and dispersivity of an aquifer. The cost of such investigations is often small in comparison to the cost of classical hydrological techniques, and in addition they are able to provide information which sometimes cannot be obtained by other techniques. Isotope hydrology can be divided into two main branches: environmental isotope hydrology, which has become especially important in those regions of the world where basic hydrological data are insufficient, and artificial-isotope hydrology. -

INFORMATION TO USERS This was produced from a copy of a document sent to us for microfilming. While the most advanced technological means to photograph and reproduce this document have been used, the quality is heavily dependent upon the quality of the material submitted. The following explanation of techniques is provided to help you understand markings or notations which may appear on this reproduction. 1.The sign or "target" for pages apparently lacking from the document photographed is "Missing Page(s)”. If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting through an image and duplicating adjacent pages to assure you of complete continuity. 2. When an image on the film is obliterated with a round black mark it is an indication that the film inspector noticed either blurred copy because of movement during exposure, or duplicate copy. Unless we meant to delete copyrighted materials that should not have been filmed, you will find a good image of the page in the adjacent frame. If copyrighted materials were deleted you will find a target note listing the pages in the adjacent frame. 3. When a map, drawing or chart, etc., is part of the material being photo graphed the photographer has followed a definite method in "sectioning" the material. It is customary to begin filming at the upper left hand corner of a large sheet and to continue from left to right in equal sections with small overlaps. If necessary, sectioning is continued again—beginning below the first row and continuing on until complete. -

Information Sheet on Ramsar Wetlands 1. Date this sheet was completed/updated: 28 January 2001 2. Country: Algeria 3. Name of wetland: Chott el Hodna 4. Geographical coordinates: 35° 18’ - 35° 32’ North latitude 4° 15’ - 5° 06’ East longitude 5 Altitude: 390–400 metres 6 Area: 362,000 hectares 7. Overview: Chott el Hodna is part of a series of chotts that developed where water gathers from the Saharan Atlas in the south and the Tellien Atlas in the north. It has high steppe vegetation because it is part of the Maghrebian steppe. Its basin is located in the extreme eastern part of the high plateau, oriented west- northwest/east-southeast, 220 kilometres long and 90 kilometres wide, between two mountain formations at 1800 to 1900 metres in altitude in the north and 600 to 900 metres in altitude in the south. It is a closed water basin of 26,000 square kilometres. The bottom of the Hodna basin, an area of 8500 square kilometres and the base level of the oueds in the basin, covers an area of 1100 square kilometres. This is the Chott el Hodna, at 400 metres in altitude. This area absorbs flooding, has an elliptical form that is 77 kilometres long and 19 kilometres wide. The water is strongly brackish. The flooded area varies, but never exceeds 80,000 hectares. The chott is supplied by at least 22 main streams and freshwater springs and is covered with water only in winter. It is dry and salty in summer when a salt crust covers its whole area. -

The Baltoscandian Spinachitina cervicornis and Conochitina rugata chitinozoan biozones are recognised, and possibly also the Fungochitina fungiformis and Tanuchitina bergstroemi zones. Correlation with the Cautley Mudstones Formation of the Avalonian type Ashgill area is done with the C. rugata and the Bursachitina umbilicata chitinozoan biozones and possibly also with the F. fungiformis and T. bergstroemi chitinozoan biozones. The correlation allows an accurate dating of both formations. The Vitrival-Bruyère Formation is shown to span a much larger time interval than previously thought. The combination of litho- and biostratigraphical results from this study and those from the Puagne Inlier (western Condroz Inlier) shows diachronic boundaries for both members of the Fosses Formation. At some time during the deposition of the rugata and umbilicata chitinozoan biozones, simultaneous deposition took place of calcareous shale in the Puagne Inlier and mottled mudstone on a deeper shelf position in the Faulx-les-Tombes area. © 2006 Elsevier B.V.
