  • Abstract: Field structural analysis and microstructural analysis show that Wulonggou area has experienced a long-term structural evolution, characterized tectonically by multi-level and multi-storeyed products. Its can be broadly divided into the ductile deformation that occurred in early Triassic (240 Ma ±) and its previous period, late Indosinian - early Yanshanian (235-197 Ma) brittle-ductile deformation; brittle deformation that occurred after late Yanshanian period, especially in the early - middle Himalayan period (51-21 Ma). Late Triassic-Early Yanshanian brittle-ductile deformation was accompanied by orogenic uplift, and its performance was exhibited by the folding and faulting of the pre-existing metamorphic core on the northeast wing of the tectonites, which laid the foundation of the NWW-trending main tectonic line in the Wulonggou area, i.e., a number of formal NWW-trending ductile shear zones exhibit parallel distribution, with the tectonic activities developed in order of left-handed positive sliding- left-handed thrusting →right-handed positive sliding.
