Supplemental Material: Rare metal enrichment during magmatic-hydrothermal evolution in lithium-cesium-tantalum pegmatite: Evidence from in situ elemental and boron-isotopic variations in micas from the Shaliuquan pegmatite along the northern margin of the Qaidam Basin, China

Key Points

• Elemental variations in micas indicate significant rare metal enrichment during pegmatitic formation in the Qaidam Basin.
• Boron-isotopic analyses reveal distinct patterns, suggesting a complex magmatic-hydrothermal evolution.
• Observational analysis provides evidence from in situ measurements across various locations within the Shaliuquan pegmatite.
• Findings highlight the significance of understanding pegmatite formation for exploring rare metal resources.
