Dr. Sarah Carmichael

Sarah Carmichael is a geochemist who specializes in fluid-rock reactions in both ancient and modern environments; these include studies of diagenetic and hydrothermal reactions in carbonates and carbonatite volcanic rocks, geochemical signals preserved through mass extinctions, the formation of organic-rich shales, microbially mediated reactions at the earth's surface, and metasomatism at mid-ocean ridges.
