“…In the southwestern part of China, Rb mineralization is mainly divided into three types. The first one is related to highly fractionated granite and granite pegmatite dykes, forming Rb, Li, Be and other polymetallic deposits in the Mesozoic and Cenozoic, including Jiajika, Dahongliutan, Gariatong, Nading and other deposits (Wang, 2019). The second type is mainly related to the salt lakes in the Qinghai-Tibet Plateau, forming Rb, Li, Cs and Sr mineralization in these lakes, most of which were large and super large (Sun et al, 2019).…”

Rubidium (Rb) deposits mostly occur in the South China and Central Asia orogenic belts and are often closely associated with highly differentiated granites. This study aimed to investigate a newly discovered giant Rb deposit at Gariatong in the Central Lhasa terrane in Tibet. Detailed field studies and logging data revealed that the Rb mineralization mainly occurrs in monzogranite and is related to greisenization. LA‐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, respectively. The monzogranites are characterized as strongly peraluminous with high contents of SiO2, Al2O3, K2O, and Na2O and a high differentiation index. They are enriched in light rare earth and large ion lithophile elements with significant negative Eu anomalies and depleted high field‐strength elements. Petrological and geochemical features of these ore‐related monzogranites suggest that they are highly fractionated S‐type granites and derived from remelting of crustal materials in a post‐collisional setting. The geochemistry of zircon and apatite points to low oxygen fugacity of the ore‐related monzogranite during the magma evolution. The discovery of the Gariatong Rb deposit suggests that the Central Lhasa terrane may be an important region for the rare metal mineralization.
