Sediment Transport and Aqueous Alteration in a Mars-Analog Glacial SystemThe bulk of the Martian crust is basaltic with a wide variety of subsequently derived aqueous alteration phases. Study of analogue terrains is vital to better understand the weathering of such mafic bedrock at a range of surface temperatures. Moreover, climatic models have suggested that the early Martian climate was not warm and wet, but cold and icy, with some of the apparent fluvial and lacustrine features attributable to transient melting of ice sheets as opposed to persistent surface water. This study examines sediment samples from Collier glacial valley, Three Sisters, Oregon (OR), with the aim of better characterizing erosion, transport, and in situ aqueous alteration in a glaciated Mars-analogue terrain.
