Chemistry of interstitial waters of ODP Leg 117 samples (Table 1)

Interstitial water analyses made at 12 sites during Leg 117 are used to define the nature of diagenetic reactions in organic-rich sediments on the Owen Ridge and Oman Margin. Minor variations in chloride concentration profiles are ascribed to past changes in bottom water salinity at two mid-depth margin sites and to upward migration of low salinity water at another. There is no evidence for subsurface brine movement, unlike the case on the Peru Margin. Dolomitization is widespread and accounts for the depletions of magnesium observed in pore waters at variable depths at nearly all sites. The mineral occurs both as disseminated euhedral limpid crystals and, in at least one location, in massive stringers. Formation of the latter is suggested to reflect precipitation during sea level transgressions when the sedimentation rate was low, but when productivity was high. Authigenic carbonate fluorapatite is also widespread, the phosphorus being derived from the breakdown of organic matter. Sulfate is quantitatively depleted at depth at most locations but the rate of depletion is markedly less than that observed on the Peru Margin where sedimentation is also similarly influenced by high rates of upwelling. The reason for this contrast is not clear and merits further investigation.

Marco Aurelio : filosofía y discurso íntimo

La obra de Marco Aurelio es la manifestación final de la ética estoica. El Emperador de Roma vive continuamente en medio de muchas guerras por la defensa de su territorio. Pueblos germánicos atacaban sus fronteras en el noreste cuando puso en orden para sus amigos muchos pensamientos o notas recopiladas durante años. Estas notas tienen forma de un cuaderno de notas o de un diario íntimo y contenido filosófico. Las teorías contemporáneas de la autobiografía han estudiado estas formas y definen sus rasgos con precisión, pero existen múltiples diferencias entre la personalidad de los hombres antiguos y modernos. Esto vuelve espinosa la interpretación de los pensamientos aurelianos si usamos solamente los conceptos actuales de la literatura íntima. Nuestro artículo muestra estas dificultades.
