Petrology and Geochemistry of the Seafloor (MUHS-P)

In the "Petrology/Geochemistry of the Seafloor" group (MUHS-P), we investigate the morphology through multi-beam seafloor mapping, volcanology, petrology, geochemistry and geochronology of igneous (primarily volcanic) rocks from the seafloor from a variety of tectonic settings. Our focus has been on intraplate volcanism, including isolated seamounts and seamount provinces, hotspot tracks and large igneous provinces forming oceanic plateaus. We also investigate subduction zone volcanism (volcanic arcs and remnant arcs), as well as mid-ocean-ridge and back-arc spreading centers. Our expertise includes submarine sampling, especially of Mesozoic volcanism, and crossing the shoreline studies. The research group maintains facilities for melt inclusion and radiogenic isotope studies. In addition to bathymetric mapping of seafloor volcanic terranes, we carry out sampling with chain-sack dredges, remotely-operated vehicles (ROVs) and TV grabs. We also carry out studies on terrestrial volcanism related with submarine volcanic areas, including ocean island volcanoes (both intraplate and in volcanic arcs), continental active volcanic margins and flood basalts related to continental breakup.
