摘要
邵武—河源断裂带包含3条形态各异、特征不同的较大断裂带 ,北段为邵武—石城断裂带 ,中段为瑞金—寻乌断裂带 ,南段为龙川—河源断裂带。本文侧重阐述、分析江西境内该断裂带挽近地质时期的活动及与之有关的地貌、地震、温泉和地裂缝特征 ,探讨其活动性以及对地壳稳定性的影响。分析认为 ,邵武—河源断裂带现今还处于活跃期 ,但引起高级别地震可能性比较小 。
The Shaowu-Heyuan Faulted Belt is composed of three major fault zones different in geometry and features,which are known as the Shaowu-Shicheng fault zone in the north,the Ruijin-Xunwu fault zone in the middle,and the Longchuan-Heyuan fault zone in the south.This paper deals in particular with the activities of this Faulted Belt in the Recent and Late Periods within the territory of Jiangxi,highlighting the relevant features in geomorphology,seismology,hot spring and surface crack.A discussion is also given on the influence of its activity on crustal stability.Study has revealed that the Shaowu-Heyuan Faulted Belt is still in an active period.However,the possibility of initiating high magnitude earthquake is small,although dispersed small earthquakas cannot be precluded.
