L'objectif principal de l'etude hydrochimique est de mieux caracteriser la qualite des eaux souterraines de la nappe profonde des graviers et ses variations dans l'espace et dans le temps dans le but de determiner l'importance de la pollution, notamm

L'importance de l'etude des relations entre les couches aquiferes constitue une donnee principale du bilan de l'eau. L'etude des cartes piezometriques permet de deceler ces communications souterraines. Cette etude est particulierement importante dans

Since the construction of the anti-salting Diama dam, a resumption of aeolian deflation has been observed in the Senegal delta and particularly in Diawling National Park. It results in the formation of many clay dunes with high salt concentrations. T

L'étude des dunes argileuses est largement employée pour la reconstitution des paléo-environnements. L'arrêt de la sédimentation éolienne est généralement attribuée à des modifications climatiques ou hydrologiques. Notre étude, menée dans

The influence of rare-earth (RE) impurities on the thermoluminescence (TL) of ZrSiO4 phosphors is studied by recording the TL curves and TL emission spectra of a number of synthetic ZrSiO4 samples, doped individually with the trivalent elements of th

Tungsten minerals scheelite CaWO4 and ferberite FeWO4 (or wolframite (Fe,Mn)WO4) are met in nature in different contexts. They may also form by the alteration of each other. We have studied this type of reaction experimentally, by reacting a solution

Using chemical analysis, X-ray, infrared (IR) and thermoluminescence (TL), a study was made of the famous pegmatitic zircons of Narssârssuk (south Greenland). The results indicate that these crystals have important variations in their major- and tra
