The metamorphic basement in the Yunkai area of western Guangdong is complex,and the geologocal mapping of the metamorphic and deep metamorphic series of the Yunkai Group-complex is challenging.In recent geological survey,the authors explored the possibility of using lithological composition,spatial distribution,and contact relationship,the authors argue that the Yunkai Group-complex and the Tiantangshan Group-complex are the same stratigraphic unit.They also propose that the Yunkai Group-complex is divided into the first formation-complex,second formation-complex,the third formation-complex,the Shanping Formation-complex and the fourth formation-complex.The Shanping Formation-complex is 10-30 min thickness,mainly consisting of siliceous rock and widely distributed in the Yunkai area of Guangdong and Guangxi.The Shaping Formation-complex marks the boundary between the third and the fourth formation-complex of the Yunkai Group-complex.
