However, field evidence for the high-pressure production and storage of solid organic compounds is missing. Here, we examine forearc serpentinite clasts recovered by drilling mud volcanoes above the Mariana subduction zone. Notable correlations between carbon and iron stable-isotope signatures and fluid-mobile element (B, As and Sb) concentrations provide evidence for the percolation of slab-derived CO\n            <jats:sub>2<\/jats:sub>\n            -rich aqueous fluids through the forearc mantle. The presence of carbonaceous matter rich in aliphatic moieties within high-temperature clasts (&gt;350\u00b0C) demonstrates that molecular hydrogen production associated with forearc serpentinization is an efficient mechanism for the reduction and conversion of slab-derived CO\n            <jats:sub>2<\/jats:sub>\n            -rich fluids into solid organic compounds. These findings emphasize the need to consider the forearc mantle as an important reservoir of organic carbon on Earth.\n          <\/jats:p>","DOI":"10.1126\/sciadv.abo2397","type":"journal-article","created":{"date-parts":[[2022,9,16]],"date-time":"2022-09-16T17:58:17Z","timestamp":1663351097000},"source":"Crossref","is-referenced-by-count":45,"title":["High-pressure synthesis and storage of solid organic compounds in active subduction zones"],"prefix":"10.1126","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2057-2906","authenticated-orcid":true,"given":"Baptiste","family":"Debret","sequence":"first","affiliation":[{"name":"Universit\u00e9 Paris Cit\u00e9, Institut de physique du globe de Paris, CNRS, Paris, France."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9866-3114","authenticated-orcid":true,"given":"B\u00e9n\u00e9dicte","family":"M\u00e9nez","sequence":"additional","affiliation":[{"name":"Universit\u00e9 Paris Cit\u00e9, Institut de physique du globe de Paris, CNRS, Paris, France."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8832-4840","authenticated-orcid":true,"given":"Bastien","family":"Walter","sequence":"additional","affiliation":[{"name":"Universit\u00e9 de Lorraine, CNRS, GeoRessources, Vandoeuvre-l\u00e8s-Nancy, France."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"H\u00e9l\u00e8ne","family":"Bouquerel","sequence":"additional","affiliation":[{"name":"Universit\u00e9 Paris Cit\u00e9, Institut de physique du globe de Paris, CNRS, Paris, France."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2647-3864","authenticated-orcid":true,"given":"Pierre","family":"Bouilhol","sequence":"additional","affiliation":[{"name":"Universit\u00e9 de Lorraine, CNRS, CRPG, Nancy, France."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nadine","family":"Mattielli","sequence":"additional","affiliation":[{"name":"Laboratoire G-Time, DGES, Universit\u00e9 Libre de Bruxelles (ULB), Brussels, Belgium."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1432-436X","authenticated-orcid":true,"given":"C\u00e9line","family":"Pisapia","sequence":"additional","affiliation":[{"name":"Universit\u00e9 Paris Cit\u00e9, Institut de physique du globe de Paris, CNRS, Paris, France."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4947-3784","authenticated-orcid":true,"given":"Thomas","family":"Rigaudier","sequence":"additional","affiliation":[{"name":"Universit\u00e9 de Lorraine, CNRS, CRPG, Nancy, France."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5837-1590","authenticated-orcid":true,"given":"Helen Myfanwy","family":"Williams","sequence":"additional","affiliation":[{"name":"Department of Earth Sciences, University of Cambridge, Cambridge, UK."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"221","reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1086\/648219"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1038\/nature10460"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1038\/ngeo2939"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1038\/nature11679"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1038\/ngeo2464"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1029\/2005GC001125"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.epsl.2010.06.039"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.1507889112"},{"key":"e_1_3_2_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0016-7037(99)00123-4"},{"key":"e_1_3_2_11_2","doi-asserted-by":"crossref","unstructured":"T.
