Influence hydrothermale dans les sédiments de fosses de la mer Rouge par l'étude de quelques éléments traces

Autores: Pierret, Marie Claire; Clauer, Norbert; Blanc, Gerard.
The Cu, Ni, Fe, Cr and Zr concentrations were evaluated to study the influence of hydrothermal activity on the sediments of six Red-Sea deeps. Comparison between the Ni/Fe and Cu/Fe ratios supports distinction between hydrothermal and non-hydrothermal sediments, whereas anti-correlation between Zr and Cr concentrations results from hydrothermal influence. The results allow us to envisage that the sediments of the Suakin Deep did not undergo a hydrothermal activity and that this hydrothermal influence was weak in the Valdivia Deep. The sediments of Port-Soudan Deep recorded a hydrothermal activity, whereas this activity was the strongest in the Thetis and Atlantis II deeps.
