| 摘 要： | 在1：5万吉林敦化小蒲柴河幅等的区域地质调查中，新发现一套变质岩系。主要由变质砾岩、黑云变粒岩、角闪变粒岩及角闪片岩等组成。岩石学及变质、变形特征表明其为一个新的地层单位，新建张三沟岩组，根据区域地层对比，将其置于古元古代。该岩组的建立，为华北板块北缘东段的陆缘活动带内元古代地层研究增加了新内容，对探讨该区的大地构造演化具有重要意义。 |
| 关 键 词： | 张三沟岩组 元古代 变质岩系 敦化 吉林 |

| Abstract: | A metamorphic rock series was newly found in Xiaopuchaihe of Dunhua,Jilin during the regional geological mapping Xiaopucaihe and its neighbouring in scale of 1:50 000. It consists of metamorphose conglomerate,biotite granulite,diastatite granulite and diastatite schist. Since the characters of rocks and metamorphose and deformation indicate that it is a new stratigraphic unit,the authors established the Zhangsangou Formation-Complex. According to regional stratigraphic correlation,the age is considered the Early Proterozoic. The establishment of the Zhangsangou Formation-Complex benefits the research on the Proterozoic of the eastern north margin orogenic zone of the Northern China Plate and is important to further study of the regional geological structural evolvement in the area. |
| Keywords: | Zhangsangou Formation-Complex Proterozoic metamorphic rock series Dunhua Jilin |
