“…There are also some ages of rare metal mineralization in the Himalaya. Qin et al (2021) reported the age of 25-24 Ma from spodumene pegmatite in the Qiongjiagang area, and which is further interpreted as the metallogenic age of lithium deposit [57]. Spodumene pegmatites of 25-23 Ma are also reported in the Pusila pluton in the Higher Himalaya [58].…”

“…Both leucogranites in Higher and Tethyan Himalaya are often highly evolved granites and are named as rare metal granites, with Li, Be, Nb, Ta, W, and Sn mineralization. In the higher Himalayan granite, Qin et al (2021) reported that there are dozens of spodumene pegmatite dikes in the Qiongjiagang area, and prospective Li 2 O resources are estimated at 1,012,500 tons, which suggested that the predicted lithium resources have reached a super large scale. Spodumene, elbaite, and lepidolite have been identified in the highly fractionated leucogranites and associated pegmatites in Pusila area near Mount Everest in the higher Himalaya [58].…”

Leucogranites in the Lalong Dome are composed of two-mica granite, muscovite granite, albite granite, and pegmatite from core to rim. Albite granite-type Be–Nb–Ta rare metal ore bodies are hosted by albite granite and pegmatite. Based on field and petrographic observations and whole-rock geochemical data, highly differentiated leucogranites have been identified in the Lalong Dome. Two-mica granites, albite granites, and pegmatites yielded monazite ages of 23.6 Ma, 21.9 Ma, and 20.6 Ma, respectively. The timing of rare metal mineralization is 20.9 Ma using U–Pb columbite dating. Leucogranites have the following characteristics: high SiO2 content (>73 wt.%); peraluminosity with high Al2O3 content (13.6–15.2 wt.%) and A/CNK (mostly > 1.1); low TiO2, CaO, and MgO content; enrichment of Rb, Th, and U; depletion of Ba, Nb, Zr, Sr, and Ti; strong negative Eu anomalies; low εNd(t) values ranging from −12.7 to −9.77. These features show that the leucogranites are crust-derived high-potassium calc-alkaline and peraluminous S-type granites derived from muscovite dehydration melting under the water-absent condition, which possibly resulted from structural decompression responding to the activity of the South Tibetan detachment system (STDS). Geochemical data imply a continuous magma fractional crystallization process from two-mica granites through muscovite granites to albite granites and pegmatites. The differentiation index (Di) gradually strengthens from two-mica granite, muscovite granite, and albite granite to pegmatite, in which albite granite and pegmatite are highest (Di = 94). The Nb/Ta and Zr/Hf ratios of albite granite and pegmatite were less than 5 and 18, respectively, which suggests that albite granite and pegmatite belong to rare metal granites and have excellent potential for rare metal mineralization.

“…At the boundary of India Plate and Eurasian Plate, they stuck together, resulting in the stratum for each continental tangled together and formed the Nappe tectonic system. This geologic movement exerted stress on the stratum and caused the movement of different layers [3][4][5][6]. And due to the difference in the rock physical properties, such activity caused the relative slide, some layer went over anther, and some went under another, forming interlayer-gliding facture zone.…”

The Gangdise metallogenic belt has been a popular mineral mine since it was discovered due to its various types of mineral elements, such as copper, iron, zinc, molybdenum, silver, gold, and bismuth, attracting millions of researchers. Moreover, the possible copper output that has been indicated here has already reached 3,000,000 tons. The deposit here is a typical skarn type ore rich in garnet. The article mainly introduces how the minerals in Gangdise metallogenic belt is distributed and investigates how the Gangdise metallogenic belt is formed. Some hypotheses in this article refer to previous investigations in the Gangdise metallogenic belt. This paper concludes that the reasons for the formation of the major ore deposit in Gangdise metallogenic can be regarded as the movement of the Eurasian Plate and India Plate, which can also be defined as the main collision phase, though other geologic changes altered the distribution of the ore body later.

“…For example, leucogranite emplacement into the THS created a skarntype super-large Be-W-Sn ore in the Himalayan Cuonadong dome (Li et al, 2017;Fu et al, 2021). For the newly defined Qiongjiagang super-large lithium ores (proposed as 1 million tons), the whole-rock Li 2 O content in pegmatites can reach 1.5-3 wt% (Liu et al, 2021;Qin et al, 2021). The mineral reserves of the Qiongjiagang and Cuonadong super-large, rare metal ores are preliminary estimates and must be further determined by industrial departments.…”

This paper introduces how crustal thickening controls the growth of the Himalaya by summarizing the P‐T‐t evolution of the Himalayan metamorphic core. The Himalayan orogeny was divided into three stages. Stage 60–40 Ma: The Himalayan crust thickened to ∼40 km through Barrovian‐type metamorphism (15–25 °C/km), and the Himalaya rose from <0 to ∼1000 m. Stage 40–16 Ma: The crust gradually thickened to 60–70 km, resulting in abundant high‐grade metamorphism and anatexis (peak‐P, 15–25 °C/km; peak‐T, >30 °C/km). The three sub‐sheets in the Himalayan metamorphic core extruded southward sequentially through imbricate thrusts of the Eo‐Himalayan thrust, High Himalayan thrust, and Main Central thrust, and the Himalaya rose to ≥5,000 m. Stage 16–0 Ma: the mountain roots underwent localized delamination, causing asthenospheric upwelling and overprinting of the lower crust by ultra‐high‐temperature metamorphism (30–50 °C/km), and the Himalaya reached the present elevation of ∼6,000 m. Underplating and imbricate thrusting dominated the Himalaya' growth and topographic rise, conforming to the critical taper wedge model. Localized delamination of mountain roots facilitated further topographic rise. Future Himalayan metamorphic studies should focus on extreme metamorphism and major collisional events, contact metamorphism and rare metal mineralization, metamorphic decarbonation and the carbon cycle in collisional belts.
