Deep microbial life in subduction zone

A chemical analysis of organic matter encapsulated in rocks from a serpentine mud volcano above the Izu-Bonin-Mariana subduction zone in the Pacific Ocean indicates that microbial life deep within or below the mud volcano may have produced the organic matter, and a heat conduction model estimates that life could exist approximately 10,000 meters below the adjacent seafloor, potentially providing a shelter for life in the violent phases of Earth’s history. - Read at PNAS
