Meso-Neoproterozoic Yunkai Group complex is lithologically composed of the middle-low grade metamorphic series in southeastern Guangxi, which formed a series of zones of progressive metamorphism from greenschist facies to amphibolite facies.
桂东南中新元古界云开岩群是一套中浅变质岩系,并形成一系列绿片岩相-角闪岩相的递增变质带,通过对云开岩群角闪岩相变质带(十字石-蓝晶石带)中斜长角闪岩变质作用的PT轨迹的系统研究显示,其包括了由早期绿片岩相变质阶段(M1)→峰期角闪岩相变质阶段(M2)→近等温降压变质阶段(M3)→近等压降温变质阶段(M4)→晚期绿片岩相退变质阶段(M5)五个阶段的顺时针PT演化轨迹,其地质动力学过程属于典型的板块俯冲碰撞→抬升模式,表明云开地块北缘造山带的地质构造演化经历了俯冲碰撞及碰撞后的快速抬升过程。

Through the 1∶250,000 regional geological survey of the Yulin sheets of the southeastern Guangxi,this paper has distinguished an archaic unconformity event from metamorphic series that had been named Yunkai Group formerly,showing that the middle-shallow metamorphic series unconformity cover on the middle-deep metamorphic series.
通过详细的地质填图,在云开地区原定为“云开群”的变质岩系中识别出古老的不整合事件,表现为中浅变质岩系不整合覆盖在中深变质岩系之上,二者在岩石组合、原岩沉积环境以及变形变质特征上均存在较大的区别,同位素年龄及变质作用P-T-t轨迹的研究证明上覆中浅变质岩系明显晚于下伏中深变质岩系形成。

Based on progress made in the study on the chronostratigraphy of the “Qinghezhen Group” or “Kaiyuan Group”, such as SHRIMP ages of 2497±27 Ma and 2522±17 Ma obtained from the Beidagou and Wujiapuzi Formations in the Shangfeidi section, SHRIMP age of 247.
本文根据“清河镇群”(或“开原岩群”)年代地层学研究新进展,即在上肥地剖面原划入北大沟组、吴家堡子组,尖山子水库大坝原划入北大沟组等地层中获得的岩浆结晶锆石(SHRIMP)年龄2497±27Ma、2522±17Ma,250±5Ma;在“白砬子组”(或“照北山岩组”)之建组剖面东杨木林子的大理岩(结晶灰岩)中获得震旦纪之微古植物化石——Stictosphaeridiumtortutosum,Synsphaeridiumsp。

The radioactive element distribution in the granulites and charnockites of the Precambrian basement of Yunkai,Western Guangdong,has been determined.
粤西云开前寒武纪基底的麻粒岩、紫苏花岗闪长岩和紫苏闪长岩的放射性元素分布具有明显的规律，Ｋ／Ｒｂ比值分别为１１７～２０２，９４～１２９，７８～８９，Ｔｈ／Ｕ比值分别为１５～３０，１１～２０，２５～７８，Ｕ的含量范围分别为０。
