This data includes in-situ major and trace element data of lithium aluminosilicate minerals and beryl, and in-situ major element data of niobium tantalum oxide. The samples were collected from Kuqu leucogranite and granite pegmatite in the eastern Himalaya. The data of major mineral elements are obtained by electron microprobe, and the data of trace mineral elements are obtained by laser ablation inductively coupled plasma mass spectrometry. The obtained data can reveal the complex crystallization environment during mineral formation, show the supersaturation caused by crystallization differentiation and supercooling and fluid action, reflect the evolution degree of crystallization environment and magmatic differentiation, and explore the evolving relationship between leucogranite and granite pegmatite and the prospect of rare metal mineralization.

File naming and required software

The data is stored in Excel format. The file name is "spdmajtra", which represents the major and trace element data of spodumene; The file name is "brlmajtra", which represents the major and trace element data of beryl, and the file name is "colmaj", which represents the major element data of coltan.
