NASA MESSENGER mission data to measure chromium on Mercury

Co-author Asmaa Boujibar, of Western Washington University, who performed the modeling described in the paper, added: “Our model, based on laboratory experiments, confirms that the majority of chromium in Mercury is concentrated within its core. Due to the unique composition and formation conditions of Mercury, we cannot directly compare its surface composition with data obtained from terrestrial rocks. Therefore, it is essential to conduct experiments that simulate  the specific oxygen-deficient environment in which the planet was formed, distinct from Earth or Mars.”
