A field campaign targeting high pH, H2-, and CH4-emitting serpentinite-associated springs in the Zambales Palawan Ophiolites of Philippines was conducted 2012-2013, enabled description several sourced altered pillow basalts, gabbros, peridotites. We combine observations temperature, conductivity, dissolved oxygen, oxidation-reduction potential with analyses major ions, inorganic carbon, organic gas phases order to model activities selected important microbial metabolism, rank feasible...
In the Zambales ophiolite range, terrestrial serpentinizing fluid seeps host diverse microbial assemblages. The fluids fall within profile of Ca(2+)-OH(-)-type waters, indicative active serpentinization, and are low in dissolved inorganic carbon (DIC) (<0.5 ppm). Influx atmospheric dioxide (CO2) affects solubility calcium carbonate as distance from source increases, triggering formation meter-scale travertine terraces. Samples were collected at along outflow channel to determine subsurface...
Gas seeps emanating from ophiolites at Yanartaş (Chimaera), Turkey, have been documented for thousands of years. Active serpentinization produces hydrogen and a range carbon gases that may provide fuel life. Here we report newly discovered, ephemeral fluid seep small gas vent Yanartaş. Fluids biofilms were sampled the source points downstream. We describe site conditions, microbiological data in form enrichment cultures, scanning electron microscopy (SEM), nitrogen isotopic composition...
