我国西南天山造山带分布着一条长200km的蓝闪片岩带,该带西延与吉尔吉斯南天山阿特巴什蓝片岩-榴辉岩带相连,在我国境内一直没有发现榴辉岩.笔者于1995年夏季前往昭苏县阿克牙孜河上游进行考察,发现了榴辉岩,现简要报道如下.1 区域地质概况及榴辉岩的产状特征西南天山造山带是塔里木板块和伊犁中天山板块间的古生代造山带,为古亚洲洋演化史上的一个重要构造域.沿造山带北部展布有一条近东西向的早古生代缝合带,即中天山南缘断裂带.缝合带北侧为由前寒武纪角闪岩相变质岩、上志留统巴音布鲁克组岛弧火山岩和
In the southwestern Tianshan orogenic belt of China, there is a 200-km-long blue-flash schist belt which is connected with the Atterbus blueschist-eclogite belt in the southern Tianshan Mountains of the Kyrgyzstan, and no eclogite has ever been found in China. In the summer of last year, he went to the upper reaches of the Akeya River in Zhaosu County for investigation and discovered eclogite, which is briefly reported as follows: 1 Regional Geological Survey and Characteristics of Eclogite The Southwest Tianshan orogenic belt is the Tarim plate and the Yili Tiantan plate Paleozoic orogenic belt is an important tectonic domain in the evolutionary history of the ancient Asian continent.The northwestern part of the orogenic belt is spreading a near-EWP suture zone, that is, the southern margin of the middle Tianshan Mountains.The northern part of the suture zone consists of Cambrian amphibolite rock metamorphic rocks, the Upper Silurian Bayinbuluke Islands volcanic rocks and
