Fig. 1: Tectonic map showing the Cambrian SSZ ophiolites and high-grade metamorphic belts of the CAOB.
From: Ophiolites in the Central Asian Orogenic Belt record Cambrian subduction initiation processes
The main tectonic units of the CAOB are modified from Xiao et al.23 and Zhu et al.24. Cambrian HP-UHP metamorphic rocks (red stars): 1-Tsengel; 2-Urgamal; 3-Tsakhir Uul; 4-Kokchetav. The Cambrian granulitic metamorphic rocks along the margins of Siberian craton and the Khondalite belt in NE China are indicated by yellow stars.
