1. Organics in hydrothermal fluids from ultramafic-hosted vents of the Mid-Atlantic Ridge
Abstract : The process of serpentinization at slow spreading ridges is due to the circulation of seawater through outcropping mantle rocks. The peridotites of the mantle are altered via fluid-rock interaction generating, in the presence of Fe bearing minerals, high CH4- and H2-concentrations in the water column. READ MORE

2. Origin of organic compounds in fluids from ultramafic-hosted hydrothermal vents of the Mid-Atlantic Ridge
Abstract : Natural gas, primarily methane (CH4), is produced in substantial amounts in ultramafic-hosted hydrothermal systems. These systems could also generate oil (heavier hydrocarbons) and the first building blocks of life (prebiotic molecules). In the presence of iron bearing minerals, serpentinisation reactions generate H2. READ MORE
