BALANCED SECTIONS IN THE XUZHOU SUZHOU AREA

摘要: 通过对横贯全区的３条构造平衡剖面的制作与分析，在徐宿地区推覆构造细结构及深部构造特征等问题上获得了新认识，确证了台阶状逆断层和断层相关褶皱普遍存在。复原剖面研究表明，其变形缩短率为４０．５％～６２．４％，说明研究区的推覆变形具有显著的地壳缩短与增厚作用Abstract: In light of an analysis of three tectonic balanced sections across the Xuzhou Suzhou area,the authors have got a new understanding of the fine structure and deep structure of the nappe in the area and confirmed the common existence of step reversed faults and their related folds.A study of the reconstructed sections indicates a shortening rate in the range of 40.5% to 62.4%,showing that the deformation of the nappe in the study area is obviously characterized by crustal shortening and thickening.
