| Abstract: | By studying strata,sedimentary formation,tectonic-rock-associaton,deformation,metamorphism,Palaeobio-division,crustal structure,geophysical signature and geochemical features in easternTianshan and neighbouring areas,different scale tectonic units and tectonic-sedimentary factes zones aresubdivided by taking the Kangguertage-Huangshan deep fracture as boundary.There are 202 metallic oredeposits in this analysis.We pay more attention to studying the relation between the distribution of gold,silver,cupper,nickel,molybdenum,iron deposits and plate tectonics and collision zone.The area is divided into nine metallogenic belts and three metallogenic epochs in which the mid-late Variscan metallogenic epochis the most important one. There are close relation between ore-forming and subduction-collision zone andductile shear zone on the edge of the plate tectonics.Exchanging between the metallogenic zoning controlledby the tectonic division and the metallogenic concentrated epoch controlled by the tectonic evolution plays animportant role in the metallic ore deposits. |
