A geochemical study of the winonaites: Evidence for limited partial melting and constraints on the precursor composition [PDF]
, 2017 The winonaites are primitive achondrites which are associated with the IAB iron meteorites. Textural evidence implies heating to at least the Fe, Ni–FeS cotectic, but previous geochemical studies are ambiguous about the extent of silicate melting in ...

Radiometric Constraints on the Timing, Tempo, and Effects of Large Igneous Province Emplacement
Geophysical Monograph Series, Page 27-82., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Groupoid Analysis of Pyroxenes
Crystal Research and Technology, 2023 AbstractThe structure and space‐group symmetry of modular structures can be obtained from the knowledge of the structure and subperiodic symmetry of the modules and of the structure‐building operations. This leads to a space groupoid, which contains all the partial operations relating any pairs of modules.

An experimental study of pyroxene crystallization during rapid cooling in a thermal gradient: application to komatiites [PDF]
Solid Earth, 2014 To investigate the crystallization of pyroxene in spinifex-textured komatiites, we undertook a series of experiments in which compositions in the CaO-MgO-Al2O3-SiO2 CMAS system were cooled rapidly in a thermal gradient.

Combustion and Pyrolysis EA-IRMS Techniques to Determine the δ<sup>2</sup>H of Diamonds. [PDF]
Rapid Commun Mass SpectromABSTRACT Rationale Diamonds are generally considered to be metasomatic minerals originating from the Earth's mantle. They formed through the interaction of carbon‐bearing fluids or melts with the surrounding deep lithology. Most knowledge about the formation of diamonds comes from studying their mineral inclusions or stable isotopes.
