Titanium-rich basaltic melts on the Moon modulated by reactive flow processes
The origin of titanium-rich basaltic magmatism on the Moon remains enigmatic. Ilmenite-
bearing cumulates in the lunar mantle are often credited as the source, but their partial melts …

Magnesium isotopic fractionation during post-serpentinization alteration: Implications for arc and oceanic Mg cycles
In recent years, numerous geodynamic studies have concentrated on serpentinites and the
serpentinization processes that occur within subduction zones. However, as an important …

How precise and how accurate can magnesium isotope analysis be by the sample-standard bracketing method?
Mg isotope compositions are widely analyzed using the sample-standard bracketing (SSB)
method on MC-ICP-MS. However, it is not clear how accurate and how precise the Mg …
