我们在鉴定新疆地质局区域地质调查大队十一分队和二分队于1979—1981年从阿尔金山采集的岩石标本的薄片中,首次发现有麻粒岩的存在,并经董申保等有关专家复核确认。这套麻粒岩分布在阿尔金山北部的太平沟(索里库里幅)和其盖布拉克—恰什坝萨依(巴什孜供幅)一带,带宽1.3公里—5公里,大致呈东西向展布。出露于塔里木台块南缘的麻粒岩,厚约500米,东段出露情况比西段好一些。麻粒岩具柱粒状变晶结构和条痕状—条带状构造,粒度多在1毫米以上,少数可达3毫
We identified for the first time the presence of granulite in the slices of rock specimens collected from the Altun Mountains between the 11th and 2nd units of the Regional Geological Survey Unit of the Xinjiang Bureau of Geology in 1979-1981 and were confirmed by relevant experts such as Dong Shenbao. The granulite is distributed in the Taipinggou (Suryagurou) in the northern part of the Altun Mountains and its Gabbrac-Qasheba Say (Supplied by Ascension) with a bandwidth of 1.3 km to 5 km, roughly showing something To the exhibition. Exposed in the southern margin of Tarim block granulite, about 500 meters thick, the eastern section of the situation better than the western section. Granulite with granular granular crystal structure and stripe - strip structure, more than 1 mm in size, a few up to 3 milliliters
