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

• Rare metal enrichment occurs during the magmatic-hydrothermal evolution of pegmatites.
• Significant boron-isotopic and elemental variations were observed in micas, highlighting important geological processes.
• Research focused on the Shaliuquan pegmatite in the Qaidam Basin, providing insights into mineral formation.
• The findings support a complex understanding of pegmatite evolution and mineral enrichment mechanisms.
