Fig. 4: Titanium isotope fractionation occurring during the ~4.5 Ga mantle differentiation event on Mars.
From: Redox evolutions of planetary mantle reservoirs constrained by titanium isotopes
The chondrite average from ref. 26 and the literature data of martian meteorites from ref. 36 are shown in gray for comparison. The (La/Yb)N values of the martian meteorites have been calculated using the literature chemical data in the Martian Meteorite Compendium originally compiled by Charles Meyer and updated and revised by K. Righter in 2017, after a normalization onto the chemical data of chondrites in ref. 75. The red dashed arrows indicate the inferred δ49Ti values of the magma sources for the depleted shergottites after correction of the Ti isotopic effects during magma generation as modeled in Fig. 2C. Error bars represent the 2se uncertainties.
