摘      要：Rubidium(Rb)deposits mostly occur in the South China and Central Asia orogenic belts and are often closely associated with highly differentiated *** study investigates a newly-discovered giant Rb deposit at Gariatong in the Central Lhasa terrane in *** field studies and logging data revealed that the Rb mineralization mainly occurs in monzogranite and is related to ***-ICP-MS U-Pb dating of zircon yielded ages of 19.1±0.2 Ma and 19.0±0.2 Ma for greisenized monzogranite and fresh monzogranite,*** monzogranites are characterized as strongly peraluminous,with high contents of SiO2,Al2O3,K2O and Na2O as well as a high differentiation *** are enriched in light rare earth and large ion lithophile elements with significant negative Eu anomalies and depleted high fieldstrength *** and geochemical features of these ore-related monzogranites suggest that they are highly fractionated S-type granites,derived from remelting of crustal materials in a post-collisional *** geochemistry of zircon and apatite points to a low oxygen fugacity of the ore-related monzogranite during the magma’s *** discovery of the Gariatong Rb deposit suggests that the Central Lhasa terrane may be an important region for rare metal mineralization.
