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

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 divisions 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.
