In the context of planetary exploration, the growing wealth of mineralogical data resources, both on Earth and beyond, has paved the way for advanced predictive methods, including mineral association analysis [1-4]. This study employs association analysis to predict previously unknown mineral occurrences, deposits, geologic environments, and mineral inventories on Earth, including a planetary analog site. Leveraging mineral association rules, this approach enables the identification of promising locations for discovering specific mineral species, along with their likelihood based on various probability metrics. Moreover, it expands to predict mineral assemblages that may be indicative of distinct planetary conditions, environments, or deposit types. This powerful recommender system aids researchers in pinpointing locations on Earth's surface or other planetary bodies where particular mineral assemblages are likely to exist, even if they have not been previously identified. Such predictive capabilities extend beyond conventional database queries, providing new insights into unexplored terrains and offering a broader understanding of planetary mineralogy. This innovative methodology opens avenues for identifying planetary analogy sites, assessing resources, and planning missions for mineralogical exploration on celestial bodies.
