Sulfur isotopes from the lunar farside reveal global volatile loss following the giant impact Open
The Moon is strongly depleted in volatile elements and exhibits heavier isotopic signatures (e.g., K, Zn) than the Earth. However, the pronounced nearside-farside dichotomy and uneven distribution of volatiles across lunar interior raise t…

A whole-scale volatile-depleted lunar interior Open
The extent of moderately volatile elements (MVE) depletion and its effects on the Moon’s evolutionary history remain contentious, partly due to unintentionally biased sampling by the Apollo missions from the Procellarum KREEP Terrane. In t…

Effects of mineralogy on ∆47 and ∆48 of carbonate-derived CO2 below analytical resolution Open
Due to the lack of direct methods capable of determining the abundance of isotopologues containing multiple heavy isotopes within the crystal lattice, carbonates are typically reacted with phosphoric acid to produce CO2 analyte for clumped…

Investigating the effect of cation substitution and mineralogy on the dual clumped isotope composition of carbonates Open
Dual-clumped isotope thermometry relies on the joint measurement of ∆47 and ∆48 in CO2 evolved from phosphoric acid digestion of carbonates (Fiebig et al., 2019). The benefit over ∆47-only measurements is i…

Re‐Assessing the Need for Apatite‐ and Dolomite‐Specific Calibrations of the Carbonate Clumped Isotope Thermometer Open
A few key methodological uncertainties remain for the carbonate clumped isotope community. One is how to compare data among published data sets that are not anchored to the InterCarb Carbon Dioxide Equilibrium Scale (I‐CDES). A second is h…
