The Yushu-Yidun arc magmatic belt has attracted much attention among geologists due to its complete record of the evolutionary process of the Sanjiang tectonic belt in eastern Tethys and its favorable metallogenic conditions. This belt is composed of the sedimentary rock series, and Late Triassic volcanic- the Indosinian and Yanshanian granite intrusions. It has long been believed that there are no Jurassic or Cretaceous strata in this area.
