Description

Deep-seated fluids uplifted with Triassic diapirs in the SE basin, and minerals precipitated from evolved evaporite fluids in the Oxfordian marls, have been characterized by Proton Induced X-ray Emission (PIXE) microanalysis. Trace amounts of Fe, Cu, ± Zn, ±Ti, ± As, ± Br have been measured in both cases, emphasizing the metallogenic potential of the diapiric fluids, and their influence during early diagenesis of the Oxfordian marls. The low Sr-content of evaporite fluids (<20 ppm) contrasts with the Sr-rich minerals deposited below the sea-floor surface. (authors). 21 refs., 1 fig., 1 tab
