Abstract:
Interstitial water data obtained during Leg 60 show complex gradients at Site 453 in a sediment pond on the west side of the Mariana Trough. Concentrations of Ca, Mg, Sr, as well as of K and Li, suggest that slightly altered sea water penetrates below the sediments, most likely through brecciated igneous and metamorphic rocks, mainly gabbros, lying at the base of the pond. Interstitial water concentration gradients suggest that reactions involving igneous matter lead to increases in calcium and strontium in the pore fluids and to decreases in magnesium. Upward advection of water through the sediments does not appear to occur, so that the advected sea water most likely penetrates deeper into the breccias, perhaps leading to further hydrothermal activity elsewhere in this area.
Interstitial water gradients at Sites 458 (conservative) and 459 suggest that reactions in the sediments and underlying basalts are responsible for increases in dissolved calcium and decreases in magnesium and potassium.
