Abstract: A late Paleozoic volcanic arc occurred in the Haerlike are, north segment of Eastern Tianshan belt, where large-scale thrust tectonism took place in the last stage of Carboniferous Period. Our study suggests that three stages of structural deformation, metamorphism and magmatism related to late Carboniferous collision-orogeny can be recognized, that is: (1) northward thrusting resulted from an oceanic plate subduction from north to south at about 346-312Ma; (2) southward thrusting 312-260Ma corresponding to the late Carboniferous intracontinental A-type subduction caused by the collision between Tarim and Siberia plateds; (3) dextral strike-slip tectonism along an E-W direction dated by an age of 260-230Ma, corresponding to a tectonic deformation in the last phase of collision-orogeny mainly along boundary faults. The large-scale thurst tectonism produced some large scale deformation zones: ductile shear zones occurred in the middle-deep crustal level characterized by feldspar-quartz facies ductile deformation, and brittle deformation zones were formed in the upper crustal position marked with fracturing and faulting. Each stage of regionally structural deformation led to strong granitic magmatism with distinct geological features and isotopic age.
