Abstract

This work depicts a synthesis of the main water-rock interaction processes controlling the water chemistry in El Berrocal granitic pluton, emphasizing in the uranium geochemistry. An uranium-sulphide dyke controls the general characteristics of the system at the site seale. Dissolution/precipitation of calcite is the most important process in the area. Uranium concentration ranges from 4x10 ·9M to 8x70 ·6M. Undersaturation with respect to most of uranium minerals occurs in the water. Adsorption...
