Gangdese porphyry copper metallogenic belt in Tibet is 2000 km long from east to west and about 100 km wide from north to south. Within the metallogenic belt, Yanshanian–Himalayan volcanic series and igneous intrusions are widely distributed and the main sedimen-tary strata consist of Cretaceous and Tertiary formations (Fig. 1).

In situ zircon U-Pb ages for the recently discovered Zhunuo porphyry copper deposit in the western part of the Gangdese metallogenic belt in Tibet were determined by sensitive high-resolution ion microprobe (SHRIMP). The ages can be divided into two separate groups, reflecting more than four major tectono-magmatic events in the area.

The study area covers ∼12,290 km 2 of central Tibet (SW China; 29°10′–29°55′N; 90°45′–93°00′E) in the Gangdese metallogenic belt, one of the most important multi-metal mineralization areas in the region (Li et al., 2019; Zheng et al., 2016, Fig. 1).Subduction of the Neo-Tethyan oceanic crust beneath the Asian Plate during the Jurassic–Cretaceous, subsequent collision of the ...
The Gangdese metallogenic belt in the Tibetan Plateau hosts many large ore deposits, of which the Xiongcun and Niangre ore concentration districts are two typical examples. Due to the insufficient geophysical evidence about the deep metallogenic dynamics across these two districts, the electrical structure was obtained by modeling ...
Abstract: The Gangdese copper-molybdenum polymetallic metallogenic belt in Tibet was not included in the national important metallogenic belts before 2001. However, the subsequent theoretical understanding and method innovation of mineralization and prospecting have led to a historic breakthrough in ore prospecting in this belt, newly finding of a series of large and super-large deposits …
