“…The Yugula nickel deposit is situated within the ultramafic rock of the ophiolite suite at the southern margin of the NLB. The quartz-vein W deposit, Jiagang (or Gariatong), is with the Carboniferous limestone and slate strata of the Yongzhu Group (Figure 3) (Lin et al, under review); the Jiaoxi W deposit is hosted in Miocene porphyritic monzogranite, sandstone, and shale, forming the quartz-muscovite-wolframite veins (Wang et al, 2018a).…”

“…Anatexis of the ancient crust and subsequent fractional crystallization could result in the substantial accumulation of tungsten in the melts and the high degree of fractional crystallization of the crustalderived magmas with a relatively low magmatic oxidation state. This process is recognized as a critical step in the development of tungsten mineralization (Wang et al, 2018a;Xu et al, 2020).…”

“…The wolframite resources in the BNMB have recently drawn extensive attention due to their economic significance and very young ages. Wang et al (2016b), Wang et al (2018a) argued that the Jiaoxi W deposit in the BNMB originated from magmatichydrothermal fluids. The geological work shows that the Jiaoxi deposit mainly developed the veinlet zone and the veinlet-large vein mixed zone according to the "Five levels" model.…”

Metallogeny in the Bangong–Nujiang belt, central Tibet, China: A review

et al. 2023

View full text Add to dashboard Cite

The Bangong–Nujiang metallogenic belt consists of scattered Tethyan oceanic blocks, mainly distributed underneath the margins of the Qiangtang and Lhasa terranes in central Tibet. A new world-class metallogenic belt has been reported in this region recently, based on the geological mapping and ore deposit prospecting over the last two decades. It currently comprises inferred resources of 30 Mt Cu and 500 t Au, together with several Cr–Ni, Fe, and W (Mo) resources, forming a significant potential area for future mineral exploration. These metals are mainly hosted in porphyry copper, skarn copper, skarn iron, orogenic gold, quartz-vein tungsten, and ophitic chromite deposits. The mineral deposits in the Bangong–Nujiang metallogenic belt have been widely recognized in different localities, including the southern edge of the southern Qiangtang block, part of the north Lhasa block, and even part of the central Lhasa block, indicating they were formed in variable geological settings, from the initial opening, subduction, and collision to the extension of the Bangong–Nujiang Ocean. Specifically, five major tectonic events contributed to mineralization, including the stage 1 (240–165 Ma) initial opening of the Bangong–Nujiang Ocean, stage 2 (165–145 Ma) oceanic subduction, stage 3 (145–100 Ma) close of the ocean, stage 4 (100–65 Ma) continent–continent collisional orogenesis, and stage 5 (65–0 Ma) post-orogenesis. At stage 1, Cr–Ni deposits were formed during the initial opening of the ocean; porphyry–epithermal Cu (Au), skarn Fe, and minor orogenic Au deposits were formed at stage 2 and stage 3; a younger pulse of a few porphyry–skarn Cu ± Mo and orogenic Au deposits were formed during stage 4; finally, W(Mo) deposits were generated in stage 5. In general, porphyry Cu systems, orogenic Au, and skarn Cu polymetallic deposits that occurred in the subduction and post-collision settings related W(Mo) deposits have the most potential for future exploration. An in-depth investigation of several scientific problems, such as addressing the tectonic setting, magmatism, and metallogeny of this region and genetic linkage of these deposit preservations to plateau uplift, is essential for the future success of exploration in the Bangong–Nujiang metallogenic belt.
