Texte intégral accessible uniquement aux membres de l'Université de Lorraine.In many metallic deposits, especially in sedimentary context and particularly in black shales, spatial or genetic relationships are described between organic matter and metals. Several black shales/schists affected by increasing thermo barometric conditions were selected to study the behavior and fate of uranium from sedimentation to high grade metamorphism. In shallow buried cambro ordovician Alum Shales (Sweden), uranium is dispersed and is not detectable as a particular mineralogical expression. Thermal maturation of the Alum Shales and hydrocarbon generation did not cause any identifiable remobilization of primary concentration, since migrated hydrocarbons did ...
