The chemical compositions of the interstitial pore-water samples measured on board the JOIDES Resolution are compared with shore-based analyses of the samples' strontium, oxygen, and carbon isotopic compositions. These analyses support conclusions of large-scale water movement through the sediment overlying the Queensland Plateau possibly leading to massive platform dolomitization. At the Queensland continental margin sites, complete sulfate reduction and abundant methanogenesis occurs, yet little evidence of these processes is seen in the δ13C of the pore waters. The failure to observe these signatures is a consequence of large-scale recrystallization of carbonate sediments masking the isotopic signatures of these processes. -from Authors
