Spectral interpretation of late-stage mare basalt mineralogy unveiled by Chang’E-5 samples
Nature Communications, 2022 Laboratory spectroscopic and X-ray diffraction analyses on the Chang’E-5 lunar soil samples have demonstrated that the spectral features of lunar late-stage mare basalts are representative of iron-rich high-Ca pyroxene rather than olivine.

Decreasing extents of Archean serpentinization contributed to the rise of an oxidized atmosphere
Nature Communications, 2021 Throughout the Archean, H2 generation via low-temperature ultramafic serpentinization likely helped prevent atmospheric O2 accumulation and continued until the abundance of ultramafic rocks diminished setting the stage for the Great Oxidation Event.
