摘要:
      以大地构造理论为基础,通过对徐州西南部的小构造尺度的断层、褶皱及其相互联系的研究,结合区域构造的特点,对前人的观点提出新的认识,并合理补充徐宿弧形构造的成因机制。结合地层的岩性特征,认为该构造的形成前期以板块挤压伴随重力滑覆为主,后期以多向重力滑脱为主,研究区的构造特征是由两期构造共同结合的产物。

Abstract:
      Based on geotectonic theory, the paper studied the fault, fold, and their relationship of the small-scale fault of southwestern Xuzhou structure. By analyzing the characteristics of regional structure, it proposed new insights on previous studies and improved the genetic mechanism hypothesis of Xu(zhou)-Su(zhou) Arc Structure. Considering the lithological characteristics, it is believed that, at the early stage of its formation, plate jams with gravitational gliding nappe played the leading role, while at the late stage, multidirectional gravitational decollement did. Tectonic characteristics in the study area is a combined product of structure formation of the two stages.
