Extensively altered brines, with a composition different from that of any previously reported natural water, have been recovered by deep coring of sediments in the Izu-Bonin fore-arc sedimentary basin. Samples from successive depths document the chemical evolution of these unusual pore waters, from sea water to highly enriched CaCl2 brines. The origin of these pore waters seems to be related to the special environment of a fore-arc sedimentary basin, where accumulation rates of volcanogenic sediment are extremely high and the sediments are susceptible to alteration.
