Himalayan Leucogranites: Rare-metal Resources
Sign Up to like & getrecommendations! Published in 2024 at "Elements"
DOI: 10.2138/gselements.20.6.401
Abstract: Himalayan leucogranites were once overlooked for rare-metal resources because they initially were thought to have formed by in-situ partial melting of underlying high-grade metamorphic rocks. However, recent findings have revealed widespread rare-metal mineralizations of Be,… read more here.
