华南地区构造复杂，中生代动力体制经历了从特提斯构造域向滨太平洋构造域的转换。雪峰山位于华南内部，其隆升机制也存在广泛争议，对雪峰山及其邻区古应力场研究，为华南大陆构造演化动力机制提供了依据。古应力反演显示，中生代以来，研究区受到NE向、近SN向、NW向、NNE向四期的构造挤压。NE向与近SN向是华南块体印支期顺时针旋转以及古特提斯洋闭合的结果， NW向挤压是古太平洋板块俯冲作用导致，而NNE向挤压则与印、藏碰撞的远程效应有关。

The structure of South China is complex, and its tectonic regimes underwent a tremendous change from the Tethys tectonic domain to the Pacific tectonic domain during the Mesozoic period. The Xuefengshan tectonic belt (XTB) is located in the interior of South China and its uplift mechanism is debated hotly. The study of stress fields on XTB and its adjacent areas provides a key basis for the dynamic mechanism of tectonic evolution of South China. The inverted stress shows that the study area has experienced four stages of compressive stress since Mesozoic, i.e., NE-trending, nearly NS-trending, NW-trending and NNE-trending compressive stresses. The NE-trending and nearly NS-trending stresses resulted from clockwise rotation of South China and closing of Tethys ocean. The NW-trendiang compression was induced by subduction of paleo-Pacific Ocean towards Eurasia continent, whereas the NNE-trending compression might have been related to the far-distance effect of collision between the India and the Tibet plates.
