This study investigates the distribution patterns and enrichment mechanisms of lithium associated with the Permian aluminous rock series in the Jiujing Syncline, Nanchuan, Chongqing. Lithium, a critical mineral for emerging industries, exhibits significant enrichment in bauxite deposits, characterized by stable horizons and large resource potential. Three profiles (Sects. 1–3) oriented west-east were analyzed for major elements using X-ray fluorescence spectrometry (XRF). Results reveal a distinct “M-shaped” vertical variation in lithium content, with enriched horizons (Li₂O > 0.1 wt%) concentrated in the middle-upper Liangshan Formation. Lithium exhibits complex correlations with Al, Ti, and Fe, transitioning through four stages of positive/negative relationships based on concentration thresholds. The findings suggest lithium likely resides in stable clay minerals (e.g., cookeite, hectorite) formed during weathering, highlighting the need for further research to elucidate enrichment mechanisms.

摘要

This study investigates the distribution patterns and enrichment mechanisms of lithium associated with the Permian aluminous rock series in the Jiujing Syncline, Nanchuan, Chongqing. Lithium, a critical mineral for emerging industries, exhibits significant enrichment in bauxite deposits, characterized by stable horizons and large resource potential. Three profiles (Sects. 1–3) oriented west-east were analyzed for major elements using X-ray fluorescence spectrometry (XRF). Results reveal a distinct “M-shaped” vertical variation in lithium content, with enriched horizons (Li₂O > 0.1 wt%) concentrated in the middle-upper Liangshan Formation. Lithium exhibits complex correlations with Al, Ti, and Fe, transitioning through four stages of positive/negative relationships based on concentration thresholds. The findings suggest lithium likely resides in stable clay minerals (e.g., cookeite, hectorite) formed during weathering, highlighting the need for further research to elucidate enrichment mechanisms.
