Kanguertag gold ore belt is an important metallogenic belt discovered in the area of easternTianshan, Xinjiang Uygur Autonomous Region. The area is seperated by Kangguertag-Huangshan deep fracture, which belongs to the first plate boundary. There is an island arc system ofLate Paleozoic Era and a giant shear zone in south of the fracture, which stretches several hundreds of km from east to west with alternating strong and weak strain. There are four stages ofdeformation of which the second and third are most closely related to gold mineralization. Thereare also important temporal and spacial relations between the late paleozoic collision and gold metallogeny. Charateristics of collision granites are clearly corresponded to the An deposits. Threestges of metallogenic tectonic evolution and six tectonic and metallogenic laws are put forward.The An deposits in the belt are obviously controled by collision and characterized by dynamic(metamorphic) hydrothermal fluid mineralization.
