Lithium-Rich Pegmatite Detection Integrating High-Resolution and Hyperspectral Satellite Data in Zhawulong Area, Western Sichuan, China

Lithium (Li) has grown to be a strategic key metal due the enormous demand for development of new energy industries over world. As one most significant sources Li resources, pegmatite-type deposits hold large share mining market. In recent years, several and super-large spodumene (Spd)-rich pegmatite have been discovered successively in Hoh-Xil–Songpan-Garzê (HXSG) orogenic belt northern Tibetan Plateau, indicative great prospecting potential this belt. Hyperspectral remote sensing (HRS), as rapidly developing exploration technology, is especially sensitive identification alteration minerals, made important breakthroughs porphyry copper deposit exploration. However, small width dykes lack typical zones, ability HRS Li-rich remains explored. study, anomalies were directly extracted from ZY1-02D hyperspectral imagery Zhawulong (ZWL) area western Sichuan, China, using target detection techniques including Adaptive Cosine Estimator (ACE), Constrained Energy Minimization (CEM), Spectral Angle Mapper (SAM), SAM with BandMax (SAMBM). Further, superimposed distribution delineated based on GF-2 high-resolution imagery. Our final results accurately identified known range Spd further predicted two areas. The approaches used study could easily extended other mineralization areas discover rare Plateau.
