| 中文摘要: |
| 研究区出露地层主要有中上元古界碧口群第四亚群,为一套低变质的细碧角斑岩系,对这套岩系的各种构造研究,揭示了这套岩石经历了四期变形,且区内存在强应变带(剪切带)与弱应变带(褶皱带)相间的构造格局。 |
| 英文摘要: |
| Tectonically,this paper refers to the contiguous areas among West Qinling fold system of Ba-Yan-Ke-La geosynclinal area and Longmenshan geodome system of North-South Diwa region.The main stratum of studied area is the fourth sub-group of middle-upper Proterozoic Erathem Bikou group which is a suite of low-grade metamorphic spilite-kerapophyre sequence formed in the course of volcanic activity.A detail study and analysis of various structural elements,strain markers and kinematic indicators reveal that the area possesses the juxtaposed intense and weak strain pattern,and that the stratum has experienced four phase structural deformations. |
