Abstract
Paleogene Phosphorites in the Syrian desert were studied for u and other trace elements. Phosphorites are granular, composed of grains (pellets, bons...) with calcite matrix. Carbonate-Fluor-Apatite (CFP) is the only phosphatic mineral detected; its characterized by a ratio of F/P{sub 2} O{sub 5} in the rang of 0.11 and CO{sub 2} content of 3.90%, which indicates a slight weathering of the studied phosphorites. Geochemically, phosphorites are enriched in some trace elements, notably: Sr, Y, La, Yb and U. These elements are linked to the Apatite by substitution to Ca in the Apatite Lattice and/or by Adsorption. Weathering provoke mobilization and redistribution of trace elements according to local conditions. uranium is partially mobilized from phosphorites by weathering, but the potential of uranium is still in the phosphorites itself. However, this potential, in the range of 55 ppm, is lower than the uranium content of the Mines phosphorites in the Central Palmyrides (up to 101 ppm in Khneifiss). (author). 29 refs., 20 figs. 5 tabs.
