TL;DR: In this article, the authors provide a synthesis of tectonic evolution, magmatism and metallogeny in the Sanjiang region based on data from literatures, and provide evidence for two different events of subduction of the Proto-Tethys ocean at different locations.

TL;DR: In this article, the authors identify the following four main phases for the Cenozoic evolution in the Sanjiang region: (i) Subduction and rollback of Neotethyan oceanic plate before ca. 45-40 Ma caused lithosphere shortening, indicated by folding-thrusting in the shallow crust and horizontal shearing in middle crust, and multiple magmatic activities, with associated formation of Sn ore deposits in the Tengchong block, Cu polymetallic ore deposits within Mesozoic basins, and Mo and Pb-Zn ore

TL;DR: Wang et al. as discussed by the authors brought up the concept of composite metallogenic system to summarize the regional metallogeny driven by superimposed orogeny, which caused the overlapping of diverse genetic types of deposit formed in different tectonic periods in the same tectono-metallogenic belt.

TL;DR: In this article, the exact location of the suture between the Simao and Yangtze blocks has been investigated, and it was shown that the detrital and inherited-xenocrystic zircons from Paleozoic sedimentary rocks and a Triassic granite dyke in the Laowangzhai-Mojiang suspect terrane belong to the same suture.

TL;DR: The Beiya porphyritic monzogranite and granite intrusions have similar isotopic compositions that are comparable to the compositions of amphibolite xenoliths hosted by potassic felsic intrusions in western Yunnan as mentioned in this paper.
