In the large Shihuiyao Rb-Nb-Ta-Be deposit, a beryl-bearing granite was identified with three texturally different zones that show an increasing degree of fractionation, including albite (bottom zone), pegmatite pockets (intermediate and intercalation layers (top zone). Beryl occurs both in intermediate top zones. Microtextural (SEM), Raman spectra, trace-element (LA-ICP-MS) data on beryl from these shed new light behavior trace elements during magmatic-hydrothermal evolution. zone, magmatic (Brl-1) has homogeneous texture, while zone (Brl-2) can be divided into (Brl-2a) metasomatic subtypes (Brl-2b). The Brl-2a shows oscillatory zonation, whereas Brl-2b is darker BSE images highly porous. Fractional crystallization led to increase Na, Sc, Fe, Rb, Cs contents Brl-1 Brl-2a. Comparing those other pegmatites worldwide reveals ideal element monitor evolution host. Distinct textural chemical features reflect alteration by dissolution-reprecipitation process for Brl-2b. combination published experimental fluid inclusion data, we propose fluids exsolved magma late-magmatic stages could transport amounts rare metals, such as Ta Rb. higher content compared suggests play favorable role mineralization. contrast, decreasing Rb attributed high mobility fluid. Such Rb-rich are expected generate orebodies economic value surrounding ore-bearing granite, implying more investigation hydrothermal mineralization district warranted.
