【摘要】 从湖南省东南地区的大地构造、新构造特征及主要第四纪断裂活动研究入手,分析了区域地震构造环境,认为新构造运动期间,地壳运动以大面积整体性缓慢抬升为主要形式,兼有间歇性不均匀抬升活动;区域断裂多为第四纪活动断裂,并存在中更新世活动断裂,然而断裂的现今活动不甚明显,对区域地质构造的分割性和控制性较弱。更多还原

【Abstract】 Starting with the research on the basic characteristics of tectonic,neotectonic and the activity of dominating Quaternary fault in the southeast of Hunan province,the regional seismotectonic environment was analyzed.It is recognized that during the neotectonic movement period,the crust has mainly undergonely entire and slowly elevated movement along with intermittence uneven elevated movement.The regional faults generally occured in the Quaternary and some in the mid-Pleistocene,but there are no distinctive activities nowadays,and the regional tectonic setting is slightly affected by them.更多还原
