| 英文摘要 | Lithium is a crucial strategic metal resource for modern China. In recent years, significant medium to large high-grade pegmatite-type lithium deposits, such as those at Kalawala, Mulinchang, Kangxiwa, Bailongshan, and Xuefengling, have been discovered in the West Kunlun rare metal metallogenic belt. To identify new rare metal deposits in regions marked by lithium-beryllium geochemical anomalies, this study employs the Bailongshan deposit in the Dahongliutan rare metal ore concentration area on the eastern margin of the West Kunlun orogenic belt as a model. The research establishes a prospecting model that integrates "Late Triassic S-type granite-pegmatite + Bayankala Group strata + emplacement in weak zones of ductile shear belts + lithium-beryllium geochemical anomalies. "To assess the potential for rare metal deposit discovery in the Keliya region, located on the eastern margin of Dahongliutan, this paper utilizes the aforementioned prospecting model as a guiding framework. It combines methodologies such as geochemistry, zircon U-Pb geochronology, and Hf-Nd isotopes in the investigation of the Keliya granite body. Comparative analyses of regional stratigraphy and tectonic settings between the Keliya and Bailongshan deposits reveal that the Keliya body is an S-type monzogranite with an average age of 207 +/- 1. 1Ma, consistent within the margin of error with the S-type two-mica granite of the Bailongshan deposit. Moreover, despite high lithium-beryllium geochemical anomalies, similar exposed strata, pegmatite outcrops, and a post-collisional tectonic setting in both regions, the magma sources of the two areas differ. Based on the above research, this paper concludes that the Keliya region is not suitable for using the prospecting theory modeled after the pegmatite-type lithium deposit of Bailongshan as a guide. |
