On Friday September 12 Tim Schroeder will present a part of the research that he did while on sabbatical at the University of Bremen, Germany.
Olivine is the most abundant mineral in Earth’s upper mantle. When it is exposed at Earth’s surface by faulting, it tends to be oxidized to form a number of different possible mineral species that are more stable near Earth’s surface. One possible chain of reactions consumes carbon-dioxide to form solid carbonate minerals. It may be possible to harness this reaction path to absorb much of Earth’s excess atmospheric carbon. Tim studied carbonate minerals formed during hydrothermal circulation through olivine-bearing oceanic crust in order to understand this process.
