    Abstract:
    The chemical sources for carbonate precipitation include alteration of basement rocks (calcium and strontium), diffusion from seawater (magnesium), recrystallization of biogenic calcite (calcium and carbon), oxidation of sedimentary organic matter (carbon), and oxidation of thermogenic methane (carbon). It is hypothesized from chemical data that Hole 858D intersected a fault zone at 28 m below the seafloor. The fault zone is believed to be a major conduit for the hydrothermal fluids discharging at the nearby vent. -Authors
