Fig. 8: An updated geodynamic model for the Permo-Triassic (~250 Ma) evolution of the South Tianshan Ocean (STO).
From: Final closure of the Paleo Asian Ocean basin in the early Triassic
The trench-paralleled slab geometry “anisotropy” (i.e., temporary flat-slab subduction beneath the CTS region in the KYCTC), during which witnesses its fate from the Triassic to Permian, is highlighted. AC accretionary complex, KYCTC Kazakhstan-Yili-Central Tianshan Continent, NTC North Tarim Craton, NTF North Tarim Fault. The schematic diagrams of various slab geometry are cited from the results of numerical modeling by refs. 103,140. Temperature is indicated by non-dimensional value, and Tm = 1 is considered the dimensionless temperature of the mantle.
