Mineral Prospectivity Mapping of Weathering-Crust-Type Ilmenite Placer Deposits Using Nested Spatial Cross-Validation and Explainable Ensemble Learning: A Case Study of the Wuding–Luquan Area, Yunnan, China
Mineral prospectivity mapping of weathering-crust-type ilmenite placer deposits is challenged by the limited number of known mineral occurrences, the lack of reliable barren-site labels, and spatial autocorrelation. This study focuses on the Wuding–Luquan area of Yunnan Province, China, and develops an eight-predictor...
