| description | Strategic rare metals have irreplaceable important use to emerging industry development. Granitic pegmatite is the main source of rare metals, and their fluid characteristics and metallogenic mechanism are hot topics. This paper mainly focuses on fluid properties and metallogenic mechanism of granitic pegmatite-type rare metal deposits. Ore-forming fluids of the granitic pegmatite-type rare metal deposits are generally enriched in volatile (B, P, F and H2O) and ore-forming elements, with low viscosity, low nucleation rate, but strong element solubility and mobility. The ore-forming fluids of the granitic pegmatite-type rare metal deposit were argued to be captured under the condition of high temperature and high pressure, or the temperature of as low as 350℃ under the condition of supercooling. The high crystallization differentiation evolution of granitic magma and the small proportion of crustal material rich in ore-forming elements are the two main mechanisms for the formation of ore-forming granitic pegmatite. Fluid immiscibility and constitutional zone refining are important means for further enrichment of rare metals in the process of magmatic hydrothermal evolution. The largest Jiajika granitic pegmatite-type lithium deposit in China is an ideal laboratory to study this kind of deposit. |
