Feldspar traces mineralization processes in the Qongjiagang giant lithium ore district, Himalaya, Tibet

•Comprehensively analyze the texture and composition of feldspar in the newly discovered giant Qongjiagang lithium district.•The research region is characterized by a unique outcrop with continuous changes in lithology along an elevation profile from 4077 m to 5533 m.•Effectively distinguish the ore-bearing properties of different Leucogranites and pegmatites.
