Abstract Sulfate-driven anaerobic oxidation of methane (SD-AOM) supports chemosynthesis-based communities and limits the release from marine sediments. Formation authigenic carbonates at active seeps is promoted by SD-AOM stoichiometry. While distinctively small δ18O/δ34S slopes pore fluid sulfate have been shown to typify modern methane-rich environments, identification such environments has difficult for geological past due lack sedimentary fluids. However, if isotopic composition were...
Abstract Marine hydrocarbon seeps are dynamic systems, which typically reflected in complex lithologies of limestones forming at these sites. In order to test if seep with their multiple generations carbonate phases reflect variable redox conditions, the rare earth element (REE) patterns from five ancient hydrocarbon‐seep localities, Hollard Mound (Middle Devonian), Iberg (Mississippian), Beauvoisin (Oxfordian), Canyon and Satsop River (Oligocene), Marmorito (Miocene) have been investigated....
Abstract Hadal trenches have been proposed as depocenters of organic material and hot spots for matter mineralization. In this study, we the first time quantified total benthic O 2 uptake in hadal using situ chamber incubations. Three tropical Pacific were targeted exhibited relatively high diagenetic activity given great water depths, that is, Mariana Trench (2.0 × 10 μmol m −2 d −1 , 10,853 m), Mussau (2.7 ± 0.1 7,011 New Britain (6.0 8,225 m). Combined with analyses carbon δ 13 C...
Abstract Gas hydrates represent a huge reservoir of methane in marine sediments, prone to dissociation response environmental changes. There is consensus that past events gas hydrate the environment mainly occurred during periods low sea level. Here, we report geochemical data for 2‐m‐thick layers seep carbonate collected from hydrate‐bearing drill core ~800‐m water depth northern South China Sea. The aragonite‐rich carbonates reveal positive δ 18 O values, confirming genetic link with...
By employing a specific particle interaction theory and high-precision equation of states for the liquid vapor phases H2, respectively, new H2 solubility model in pure water aqueous NaCl solutions is proposed this study. The established by fitting experimental data can be used to estimate at temperatures pressures 273.15–423.15 K 0–1100 bar, salt (NaCl concentration = 0–5 mol/kg) 273.15–373.15 0–230 respectively. adopting electrolyte solutions, also predict seawater without system. Within or...
After nearly 20 years of exploration, various areas the seafloor with hydrocarbon seepage have been discovered in South China Sea (SCS). Through linking subsurface and biospheres, seeps become natural laboratories to enhance our knowledge on processes migration associated hydrocarbon-based ecosystems marine environment. This review summarizes distribution macrofauna active seep SCS describes physiological characteristics three groups representative (bathymodioline mussels, pliocardiine...
