摘要
该文重点研究了湘东、赣西地区 NNE向活动走滑断裂系与地震和温泉分布之间的密切联系。结果表明 :1研究区地震和温泉主要集中在 3条 NNE向主走滑断裂带及其伴生的 P、R′断裂带 ;2高温热泉或强震震中区的基本构造样式为走滑断层左行、左阶雁列带和拉分盆地构造 ;3陆壳结构分层特征是影响该区地震作用强度的一个重要因素。
The relationship between the active NEN trending strike slip faults and the distribution of earthquakes hot springs in the area of eastern Hunan and western Jiangxi of China has been studied. The results show that:(1) the earthquakes and hot springs are mostly located in the three main NEN trending strike slip fault zones and associated P,R′ faults;(2)The basic structural patterns in the region of high temperature hot springs or strong earthquake epicentres comprise left lateral en echelon faults and pull apart basins;(3) the structural layering of the continental crust is thought to be one of the important factors that influence the seismicity in this area.
