ANALYSIS OF DEFORMATION AND ITS FORMATION MECHANISM OF
THIRD TERRACE IN NANNING BASIN
1)Earthquake Administration of Guangxi Zhuang Autonomous Region, Nanning 530022
Abstract The elevation of the Ⅲ terrace(T3) surface of the Yongjiang river around the Nanning basin was analyzed with the Sufur software. According to deformation characteristics, the terraces can be divided into subsidence terraces and erosion terraces. Based on this, a conclusion can be drawn that the deformation of the terrace is because of activation of mantle plume thermal fluid. In the Cenozoic Time, the mantle plume thermal fluid under the Brain upwells and flows eastward, which lead to upper crust getting thinner and creeping eastward with extension, both cause the terrace deforming as an anticline.
