Machine Learning for Mineral Prospectivity Mapping
Research Guide
What is Machine Learning for Mineral Prospectivity Mapping?
Machine Learning for Mineral Prospectivity Mapping applies algorithms like random forests, neural networks, and support vector machines to predict mineral deposit locations by integrating geochemical, geophysical, and remote sensing data.
Researchers use models such as random forests (Carranza and Laborte, 2014; 341 citations) and neural networks (Rodríguez-Galiano et al., 2015; 1401 citations) for prospectivity mapping. Studies from regions like the Philippines and China demonstrate these methods on real datasets with missing values or hyperspectral inputs (Sun et al., 2019; 216 citations). Over 10 key papers since 2014 evaluate performance via cross-validation.
Why It Matters
ML prospectivity mapping boosts discovery of critical minerals for green energy, reducing exploration costs in covered terrains. Rodríguez-Galiano et al. (2015) showed neural networks outperforming traditional methods in 71% of tests across global datasets. Carranza and Laborte (2014) handled small prospect numbers in Abra, Philippines, aiding data-scarce regions. Sun et al. (2020) integrated deep learning for tungsten in China, targeting undiscovered deposits amid rising demand.
Key Research Challenges
Handling Missing Data
Geochemical datasets often have missing values, complicating model training. Carranza and Laborte (2014) addressed this in Abra, Philippines, using random forests robust to absences. Still, imputation biases persist in small prospect scenarios (169 citations, Carranza and Laborte, 2015).
Hyperparameter Optimization
Manual tuning limits random forest scalability on large geospatial data. Daviran et al. (2021) proposed automated tuning, improving accuracy by 15% in Iranian cases (122 citations). Computational cost remains high for deep learning variants.
Multisource Data Fusion
Integrating Sentinel-2 hyperspectral with geophysical layers causes feature imbalance. Sun et al. (2019) used SVM and ANN in Tongling, China, but spectral noise reduces precision (216 citations). Othman and Gloaguen (2014) fused morphology for chromite detection (128 citations).
