川滇地区活动块体划分与现代构造应力场分区研究综述

Research Review of the Division of Active Blocks and Zoning of Recent Tectonic Stress Field in Sichuan-Yunnan Region

总结了30多年来川滇地区活动块体划分与现代构造应力场分区的主要研究认识,对二者之间的联系进行了初步讨论。对于川滇地区活动块体的划分,不同学者给出的宏观格局基本一致,但对其中一些次级块体的划分和边界断裂存在不同的认识。学者们对川滇地区现代构造应力场整体特征的认识较为一致,但对应力场的具体划分存在不同看法。川滇地区活动块体的划分格局基本确定了现代构造应力场的分区,但二者并不完全一致。开展这两方面的深入研究,对进一步认识川滇地区构造变形特征具有重要意义。

Reviewing and summarizing the main research results in division of active blocks and the zoning of recent tectonic stress field in Sichuan-Yunnan region for the last thirty years, then we preliminarily discuss the relation between them. For the division of active blocks in Sichuan-Yunnan region, the macro pattern given by different researchers is more or less the same, except for the division of some secondary active blocks and the boundary faults. The researchers have agreement with the general characteristic of the recent tectonic stress field in Sichuan- Yunnan region, but have different opinion on how to specifically divide the recent tectonic stress field. The divi- sions of active blocks in Sichuan-Yunnan region determine the zoning of the recent tectonic stress field, whereas they are not the same. The research on these two aspects in deep has important significance for recognizing the structural deformation characteristic in Sichuan-Yunnan region.
