调查区属西昆仑造山带中部,长期以来,由于受地形、交通等因素的限制,前人对该区域出露的变质地层研究甚少,笔者通过近几年区调工作的分析研究,认为该区存在四种变质作用类型,以区域变质作用为主,其次是接触变质作用、气-液变质作用与动力变质作用。 The investigation area belongs to the middle part of West Kunlun orogeny. For a long time, due to the restriction of topography, traffic and other factors, few studies on metamorphic strata exposed in this area have been conducted by the author. According to the analysis and study of the adjustment work in recent years, There are four types of metamorphism in the area, which are dominated by regional metamorphism, followed by contact metamorphism, gas-liquid metamorphism and dynamic metamorphism.
