Ocean Island Basalt origination
ExPeRT members explore the source of melt that produces ocean island basalts when the mantle is in the presence of volatile elements like sulfur.
Magma-Crustal Carbonate Research
In a few publications, Laura Carter explores the ways that various magma types (basalt, andesite, dacite) can interact with and break-down carbonate rocks (limestone and dolostone) that store carbon in Earth’s crust at different temperatures and depths: assimilation (consumption), thermal decomposition (heating) and skarnification (hot water reaction). This has implications for volcanic gas emissions and therefore Earth’s long-term climate.
Carbon Subduction Zone Cycling Research
Megan Duncan published her work on cycling organic carbon through subduction zones where one plate slides beneath another, melts, and releases gases back into the atmosphere via volcanoes. The results have implications for the initial rise in oxygen in Earth’s atmosphere billions of years ago and made the News.
Planetary Impact Research
Working to answer a question ExPeRT is exploring, Yuan Li and other expert members published in Nature Geoscience about how some of Earth’s unique geochemistry could have been added during some of the impacts that occurred in the Solar System’s early years, such as the moon-forming impact. This work made the News.
Mantle Heterogeneous Melting
In an overarching area of research ExPeRT explores, heterogeneities in the Earth’s mantle can lead to melting and ocean island eruptions, which was an area of investigation on which Ananya Mallik published.
One area of interest for ExPeRT is how planetary interiors form in their early stages and evolve over time to modern processes, which controls element storage and cycling, as is shown in this image from Rajdeep Dasgupta’s 2013 publication.
After experimentation, ExPeRT members identify melt generation and mineral stability on Rice’s Electron Microprobe.
On the left are some crystals that formed during cooling in a melt that generated at the experimental conditions. On the right are two different minerals, identified by their differing shades of grey, that are stable at the pressure and temperature of the experiment.
Modern Earth Processes
ExPeRT explores modern processes, like carbon and sulfur cycles and melt generation that produce crust and gases entering the atmosphere via volcanoes, like Sakurajima.
Early Earth and Deep Time Processes
ExPeRT members explore the chemical processes in early and modern planets that form interior layers and their interactions.
ExPeRT members recreate conditions of the birth of the solar system explore planetary formation, impacts, and evolution to modern processes.
