Heterogeneous distribution of H2O in the Martian interior: Implications for the abundance of H2O in depleted and enriched mantle sources (2016, background): “The most enriched shergottites are characterized by more radiogenic initial 87Sr/86Sr ratios (~0.7225), chondrite normalized La/Yb ratios of ~1.5, slightly negative e143Nd values (e.g., 8 for Shergotty), and higher magmatic fO2 (DIW+2 to +3) (Borg et al. 1997, 2003; Wadhwa 2001; Herd et al. 2002).”
Possible formation of ancient crust on Mars through magma ocean processes (2005, background): “... Sm/Nd ratios for modeled cumulates with intercumulus liquids closely fit SNC meteorite data and fall conspicuously far from both lunar and terrestrial magmas (Figure 6). Figure 6 shows that the SNC meteorites thought to come from depleted regions, for example QUE94201 and Chassigny, are encompas”
Bulk composition and early differentiation of Mars (2007, unknown): “al., 1997, 2003; Herd et al., 2002; Herd, 2003; Goodrich et al., 2003; Borg and Draper, 2003; McLennan, 2003].”
The oxygen fugacity of olivine‐phyric martian basalts and the components within the mantle and crust of Mars (2003, methodology): “The terms “mantle-like” and “crust-like” were very carefully chosen because Herd et al. (2002a) recognized that both components could be present in the mantle, where mixing during partial melting could occur, or that the crust-like component is in the martian crust, in which case, mixing would…”
Magma ocean fractional crystallization and cumulate overturn in terrestrial planets: Implications for Mars (2003, background): “From the SNC meteorites, evidence exists for magmatism from 1.3 Ga to as recently as 170 Myr before the present (e.g., Blichert-Toft et al. 1999; Shih et al. 1999; Borg et al. 2002; Herd et al. 2002).”
The age of Dar al Gani 476 and the differentiation history of the martian meteorites inferred from their radiogenic isotopic systematics (2003, background): “One phase that satisfies these criteria, and could be present in the martian mantle, is amphibole (Borg et al., 2002; Herd et al., 2002).”
A petrogenetic model for the origin and compositional variation of the martian basaltic meteorites (2003, background): “In the first, compositional variation is attributed to differentiation of mantle-derived magmas by assimilation of martian crust accompanied by fractional 1714 L. E. Borg and D. S. Draper crystallization (AFC; Jones 1989; Borg et al. 1997b; Herd et al. 2002).”
Constraints on the composition and petrogenesis of the Martian crust (2003, background): “A correlation between the degree of geochemical contamination and magmatic oxidation state [Wadhwa, 2001; Herd et al., 2002] is consistent with crustal assimilation , although recent evidence shows that the depleted source region for nakhlites could also be derived from an oxidized mantle reservoir…”
Outgassing History and Escape of the Martian Atmosphere and Water Inventory (2015, background): “%) must have been mixed with mantle material (Herd et al. 2002).”
Core formation and the oxidation state of the Earth (2005, background): “The significance of perovskite to the oxidation state of the mantle perhaps explains why terrestrial basalts are more oxidized than those of Mars [39].”

The age of the martian meteorite Northwest Africa 1195 and the differentiation history of the shergottites (2007, background): “…differences have been interpreted to reflect either varying degrees of assimilation of martian crust (e.g., Jones, 1989; Borg et al., 1997; Herd et al., 2002; McSween et al., 2003), or that they have been inherited from their mantle source regions (e.g., Borg et al., 2003; Borg and…”
The sulfur content of volcanic gases on Mars (2009, background): “If such magmas, whose redox condition and H2O content are within the range expected for Mars basalts ([Herd et al., 2002], [Herd, 2003], [Righter et al., 2007] and [Wadhwa, 2001]), constituted the dominant part of the Tharsis province, then we do not expect any exceptionally high sulfur delivery…”
Petrology on Mars (2015, background): “The enriched shergottites are also more highly oxidized than depleted shergottites (e.g., Wadhwa 2001; Herd et al. 2002) (Fig.”

The composition of Mars (2019, background): “e, wholly lithophile character of Mn, Cr and V) are also in harmony with the relatively oxidized conditions for Mars’ core formation as compared to the Earth (e.g., Wadhwa, 2001, 2008; Herd et al., 2002).”
Ventilation of CO2 from a reduced mantle and consequences for the early Martian greenhouse (2008, methodology): “The advent of trace element oxybarometers has produced a great deal of new data regarding the oxygen fugacity recorded by Martian SNC meteorites (e.g., Wadhwa, 2001; Herd et al., 2002; Shearer et al., 2006; Karner et al., 2007).”
