Trace Element and Isotopic Analysis by Laser Ablation ICP-MS of ore deposit bitumens: a Test Case with Uranium Ores from Oklo, gabon

摘要

Carbonaceous substances (CS) such as kerogen and derivative bitumens are closely linked to the origin of varous types of ore deposits. Examples are metal accumula- tions in living organisms, black shales, crude oils, solid bitumens, and coals. Although presently a marginal economic proposition, the uranium ores of OKLO Provide a classic case.
