Simplified tectonic map of the Central Asian Orogenic Belt (CAOB) and study region.
(a) Simplified geological sketch map of the CAOB showing the main tectonic sub-divisions5. The location of (b) is indicated. (b) Simplified tectonic map of the southeastern CAOB showing the main tectonic sub-divisions and the location of Fig. 2 6,12. Light grey zone represents the northern early-middle Paleozoic continental block and the Hutag Uul Block10,12 or northern accretionary orogen (NAO)6, whereas the dark grey zone represents the southern early-middle Paleozoic continental block10,12 or southern accretionary orogen (SAO)6. Published zircon U-Pb ages for early Permian-Triassic magmatic rocks in the region are from refs 12,15, 16, 17,32 and 55.
