Sediment-Hosted Geothermal Systems: review and first global mapping

Date: 2018-05-30

Sediment-Hosted Geothermal Systems (SHGS) are hybrid geological systems, where geothermal and sedimentary domains interact, leading to mixtures of inorganic and organic gases. Typically characterized by geothermal (thermometamorphic or mantle-derived) CO2 and biotic (microbial or thermogenic) CH4, SHGS occur in sedimentary basins crossed by magmatic intrusions or involved in volcanic plumbing systems. These systems can be of considerable interest for petroleum exploration and in the global evaluation of natural methane sources, but systematic studies for their characterization and worldwide distribution are missing
