Julie Bartley (Environment, Geography, and Earth Sciences) published a paper with several colleagues in The Planetary Science Journal. The article, titled “Using rover-analogous methodology to discriminate between volcanic and sedimentary origins in successions dominated by igneous composition,” reports the results of a study that develops criteria for determining whether a rock observed by a planetary rover has a volcanic or sedimentary origin. The project was intended to shed light on the observations currently being made by the Perseverance Rover, which is gathering data in Jezero Crater on Mars.
