In this paper, the TESCAN Integrated Mineral Analyzer (TIMA) automated mineral analysis system was used for the first time to systematically classify garnets by species and analyze their genesis in the Chenggang uplift zone. The results show that the garnets in the zone are mainly spessartine (65.08%), followed by grossular-almandine-spessartine (11.96%), with spessartine mostly appearing in orange, maroon, and burgundy, and grossular-almandine-spessartine mainly in pink. The numbers of pyrope end-members in pink, orange, maroon, burgundy, and purplish-red garnets are 206, 93, 10, 1, and 1 grains, respectively. Combining the information of pyrope types in other areas and the results of Cr-K surface scanning, some of the pink and orange pyrope belong to eclogite-type pyrope, while the purplish-red pyrope is presumed to be chromium-bearing pyrope due to its moderate chromium content, suggesting that this area has geological potential for diamond mineralization. Through automated spectral scanning and database comparison, the TIMA technique has efficiently identified nearly 2000 garnet minerals and successfully recognized pyrope end-members related to diamond mineralization. This not only verifies the technique""s feasibility in mineral classification and mineralogical identification but also provides a new technological pathway for studying mineral genesis and predicting mineralization.
