新疆喀拉通克铜镍矿区位于阿勒泰内生矿产成矿带的铬、铜镍及贵金属铂族元素成矿带(Ⅲ_1),其构造位置属阿勒泰古板块与准噶尔古海岔的接触部位(图1),构造背景为晚古生代海沟岛弧,玛因鄂博—额尔齐斯古俯冲带(以下简称玛—额俯冲带)位于其北15公里。目前对该矿区地质构造特征的认识尚有较大的争议,本文试图应用板块构造的理论,对 The Kalatongke copper-nickel deposit in Xinjiang is located in the Altay endogenous mineralization belt of chromium, copper and nickel and precious metal platinum group elemental metallogenic belt (Ⅲ_1), its tectonic position belongs to the contact part of Altay old plate and Junggar ancient Haicha (Figure 1 ) And tectonic setting of the Late Paleozoic seamount island arc. The Ma’ebo-Irtyshya subduction zone (hereafter referred to as the Ma-subduction zone) is located 15 kilometers north of it. At present, there is still much controversy on the understanding of geological structure features in this mining area. This paper attempts to apply the theory of plate tectonics to
