Research Group Petrology of the Ocean Crust

The continuous construction and destruction of seafloor is a hallmark of the dynamic Earth. The petrology group studies various aspects of mass and energy transport in this important part of the plate tectonic cycle that controls the chemical evolution of Earth and its reservoirs. Sampling of rocks with research vessels and deep submergence vehicles is followed by geochemical and mineralogical analyses in the lab in order to unravel how ocean crust and oceanic islands form. The group also studies hydrothermal systems that form when seawater interacts with hot ocean crust and that host massive sulfide deposits as well as unique chemosynthetic ecosystems.

Working Area

Mid ocean ridges where new oceanic crust is produced by seafloor spreading; subduction zones where oceanic crust descends into the mantle; seamounts and oceanic island volcanoes

Methods

Microscopy (thin section, scanning electron), hydrothermal autoclave experiments; geochemical analyses using electron microprobe, mass spectrometry (ICP-MS) and laser ablation ICP-MS; micro computer tomography (μ-CT); thermodynamic modeling.
