Session 5h – Submarine Volcanism and hydrothermalism: Fluids, melts and eruptions
A session on submarine volcanism and hydrothermal activity will be held at Goldschmidt Hawai’i 2022 in July. The conference is currently planned as hybrid (in-person/Hawai’i and virtual), however the in-person component is dependent on any future changes in COVID-19 protocols.
The abstract submission deadline for this session is currently on March 1st (see the abstract submission page on the Goldschmidt website), however this deadline may be extended. Visit the session page on the conference website for more information.
The vast majority of global volcanism, hydrothermal activity, and crustal formation are found at the seafloor. By analysing the compositions of hydrothermal fluids, submarine plumes and erupted volcanic products, we improve our understanding of processes occurring within many tectonic and marine settings. These datasets can provide insights into: mantle plume dynamics feeding ocean island chains, styles of submarine volcanic activity, the fractionation and evolution of magmas within the oceanic crust, melt generation and crustal formation at mid-ocean ridges, sediment and volatile cycling within subduction zones, and the formation of hydrothermal regions and ore deposits around magmatic reservoirs. Observing, sampling, and monitoring hydrothermal and magmatic activity in these environments remains a challenge, but technological advancements, modelling, and increased seafloor-surveying capabilities are improving our scientific efforts. This session welcomes research utilising geochemical and associated datasets to assess processes related to submarine volcanism, hydrothermal activity, and crustal dynamics at the seafloor. We particularly encourage the submission of cross-disciplinary studies across the marine sciences that integrate geochemical, geophysical, oceanographic, and/or computational datasets to further our understanding of seafloor activity.
