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。
2) The clouds began to break.
云开始散开。
3) Yunkai area
云开地区
1.
An integrated study of geological structural characteristics, granite petrology and time_space distribution regularity of deposits indicates that the Mesozoic lithosphere of Yunkai area experienced three tectonic evolution phases: the collision between 201 and 277 Ma, the tectonic transformation from compression to extension between 154 and 160 Ma, and the extension between 80 and 100 Ma.
文章通过对云开地区地质构造、矿床时空分布以及中生代花岗岩类岩石的岩石学及地球化学特征的综合研究,认为区内中生代岩石圈构造经历了二叠—三叠纪之间的碰撞挤压、侏罗纪的构造转换及白垩纪的拉张伸展 3个阶段的演化过程,大规模成矿作用受控于燕山早期岩石圈的构造转换及燕山晚期的拉张伸展的岩石圈动力学背

The Sedimentary chert formation (Sinian D fromation) at the top of the Precambrian in Yunkai area,western Guangdong and southeastern Guangxi displays banded,lamellated,massive and pseudobrecciated structures.
地处粤西和桂东南的云开地区前寒武系顶部的硅岩沉积建造（“震旦系Ｄ 组”），具有层状、纹理状、块状和假角砾状构造。
3.
It is the age of the isobaric cooling event of static recrystallized carbonate minerals in marble post deformation, reflecting approximately the age of metamorphism and deformation after the hydrothermal deposition in late Neo Proterozoic in the Yunkai area.
结合野外和岩相学研究结果，大理岩的Ｐｂ同位素记录了大理岩碳酸盐矿物后变形静态重结晶之后等压冷却事件，（５５５±６８）Ｍａ大致反映了云开地区新元古代末期热水沉积事件之后的一次变质变形事件的年龄，从而确立了新元古代末期热构造事件的存在，这对揭示云开地区前寒武纪地质演化历史具有十分重要的意义。
4) Yunkai Group complex
云开岩群
1.
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。
5) Yunkai Group
云开群
1.
Some Remarks on the Geologic Age and Stratigraphic Sequence of Yunkai Group in Yunkai Mountains;
云开大山云开群地层时代和层序的研究现状与新认识
2.
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。
