    • Affinity analysis of mineral co-occurrence: Predicting unknown mineral occurrences with machine learning 

      Morrison, S.M.; Prabhu, Anirudh; Eleish, Ahmed; Narkar, S.; Fox, Peter; Golden, J. J.; Downs, R. T.; Perry, S.; Burns, R. T.; Ralph, J.; Hazen, Robert (ADS, 2020-12)
      The expansion of mineralogical data resources facilitates the development of predictive methods, such as affinity analysis [1], that identify the location of previously unknown mineral occurrences, deposits or geologic ...

    • Bayesian estimation of Earth’s undiscovered mineralogical diversity using noninformative priors 

      Hystad, G.; Eleish, Ahmed; Hazen, Robert; Morrison, S.M.; Downs, R. T. (Mathematical Geosciences, 2019-03-19)
      Recently, statistical distributions have been explored to provide estimates of the mineralogical diversity of Earth, and Earth-like planets. In this paper, a Bayesian approach is introduced to estimate Earth’s undiscovered ...

      Large and growing data resources on the spatial and temporal diversity and distribution of the more than 400 carbon-bearing mineral species reveal patterns of mineral evolution and ecology. Recent advances in analytical ...

    • Interactive, Web-based Visualizations for Hierarchical Information and Knowledge in Geosciences: An Implementation on the Dana Classification and its Applications 

      Zhong, H.; Prabhu, Anirudh; Huang, F.; Eleish, Ahmed; Chastain, Katie; Thomson, Brenda; Narkar, S.; Fontaine, Kathy; Hummer, D. R.; Morrison, S.M.; Downs, R. T. (AGU, 2019-12)
      The Dana System of Mineralogy, developed by James Dwight Dana in the mid-19th century, classifies minerals by anionic composition and crystal structure. In testament to the success of its organizational philosophy, for ...
