| 摘 要： | 依据２０００余个热退磁样品，经计算获得极点６０余个，可以构成代表华南地区不同块体的视极移轨迹５条，并与已知的华北和扬子两地块的极移轨迹进行对比，结合地质构造特征，在研究区内划分出扬子、华夏两个地块和江南、怀玉山－越北两个地体。同时本文还对有关的地层对比和各地块间的演化关系作了分析讨论。

| Abstract: | Sixty poles are obtained after calculation ofmore than 2000 thermal demagnetized samples , and the polesform five apparent polar wandering paths which represent the polar wandering paths of different landmasses and terranesin South China. Based on the correlation of polar wandering poths in South China and these in North China and the char-acteristics of geological structures,the studied area can be divided into Yangtze and Huaxia blocks, Jiangnan terrane andHuaiyushan-Yuebei terrane. A discussion about the correlation of related strata and evolutlonary relationships betweenblocks is also presented in the paper. |
