CURRENT RESEARCH

The initial reason for creating this database was centered around investigations of mineral modes and major element oxides of the Apollo lunar basalts for unraveling clues to the evolution of the lunar mantle. In the process of gathering this data, I realized that multiple lunar basalt characteristics were poorly documented or entirely ignored. Determined to make the database more than just a simple table of modes and geochemical percentages for stable phase assemblage modeling (particularly since this involved reading through 300+ journal articles and the like), I included textural aspects and ages. I then applied machine learning within a spatial context to interpret data structure (complex data patterns are not immediately observable when using more traditional bivariate analyses (e.g. Harker diagrams)). 

CURRENT PROJECTS

— High P-T experiments are scheduled for Fall 2020 using a piston-cylinder apparatus.  These experiments will examine lunar mantle phase stabilities and titanium/ilmenite behavior. Phase equilibrium modeling will establish theoretical, early stable-phase assemblage boundaries considering a range of bulk silicate moon compositions.

— I use Matlab to explore numerical modeling of best-fit aspect ratios for anhedral plagioclase microlites. Aspect ratios are one part of determining crystal size distributions (CSDs) and are known to reflect growth rates and associated magmatic environments.

— The lunar nearside contains geochemical and mineralogical signatures reflecting different types of mare basalts, sourced from different upper mantle protoliths. I examine correlations among these signatures to interpret potential interior processes. To accomplish this, I use unsupervised machine learning (common in the social sciences) as an investigative tool for re-evaluating lunar mantle heterogeneity. I maintain a database of lunar basalt characteristics (ApolloBasaltDB, freely available for download in the top menu) used for both machine learning and thermodynamic modelling.

Random cuts through these forms (and others) are modeled in order to explore how crystal aspect ratios (essentially length-to-width dimensions) measured in polished sections affect the interpretation of crystal size distributions.
