The oxygen fugacity (fO2) of the martian basalts (a.k.a. basaltic shergottites) has recently been recognized as important in understanding their petrogeneses. The correlation between oxygen fugacity and certain geochemical parameters (initial Sr and Nd isotopic compositions, La/Yb ratios) indicates the presence of long-term incompatible-element enriched and depleted reservoirs, which are oxidized and reduced, respectively. Oxygen fugacity variations in the martian basalts have been modeled based on assimilation of oxidized crustal ("crust-like") material by reduced, mantle-derived magmas. However, there remains the possibility that the oxygen fugacity of the martian basalts is controlled by the nature of their source regions. Here I review existing oxygen fugacity data for the martian meteorites, present some speculative estimates for newer martian basalts, and explore the heterogeneous mantle model in more detail.
