摘要
东天山尾亚火车站以西太古宙高级变质区亚西岭片麻岩套中赋存有高级变质岩—麻粒岩,它是新疆发现阿尔金山麻粒岩后的又一次重大发现,首次证实“天山中间隆起带”有古老地块的存在,这对研究新疆大地构造具有重大的地质意义。
The discovery of garnulites from Yaxiling gneissic suite of the Archean high-grade metamorphic zone west of Weiya station of East Tianshan,following the first discovery of garnulites in Altun Mts.,demonstrates for the the first time that the old blocks exist in the 'centarl uplift zone of Tianshan'. It has an important geological singnificance on the study of geotectonics of Xinjiang.
