Predictive model of Li-Cs-Ta pegmatite deposits

This model is derived from geological and geophysical data, which is processed using deep learning and natural language processing techniques. Displayed is a Pan-Canadian probability map indicating the likelihood of discovering next-generation lithium-cesium-tantalum (LCT) pegmatites. This map was generated using known Canadian LCT pegmatites and their associated geospatial features, incorporating geological and geophysical data analyzed through deep learning and natural language processing techniques. Higher probability values highlight areas with an increased likelihood of hosting next-generation deposits, making this map a valuable tool for decision-making.

Description: Title: Creation of the probability model for Canadian LCT pegmatites -- Description: This is a probability model designed to assess the likelihood of discovering next-generation lithium-cesium-tantalum (LCT) pegmatites. The model was developed using deep learning and natural language processing (NLP) techniques. Geological text data, processed through NLP methods, were used to define covariates for the model, which were further complemented by geophysical data, including aeromagnetic and gravity datasets. Higher probability values indicate areas with an increased likelihood of hosting next-generation LCT pegmatites. For a detailed description of the methodology used to create this model, please refer to this publication: doi:10.1007/s11053-024-10438-x.
