The particulate organic matter isolated from soils and from underlying geologic formations from various French watersheds was studied under the light microscope to determine palynofacies composition. The results reveal that modern humus contain notab

The La Florida lead-zinc deposit (Cantabria, Spain), which is hosted by Urgonian carbonates, is located on the border of the Basco-cantabric Lower Cretaceous basin. The stratiform orebody, which is composed of sphalerite, galena, and barite in iron-d

In order to study the ‘in vitro’ fixation of metal ion species on algal and bacterial sedimentary organic matter, two algal mat samples have been studied. The main interest of this organic matter is its specific cyanobacterial origin. After isola

To study the influence of various metals on the natural (thermal) evolution of organic material, simulation experiments were performed by heating it and organometallic compounds derived from it, to different temperatures. Results of these experiments

The ‘in vitro’ metal fixation ability of a recent sedimentary organic matter of algal origin has been investigated with seven divalent cations (UO 2+ 2 , Ni 2+ , Mn 2+ , Zn 2+ , Co 2+ , Pb 2+ , Cu 2+ ) and three anionic species (VO − 3 , MoO 2
