岩芯地球化学特征对地震陷落事件的响应——以海南岛东寨港为例
|
摘要
根据在海南岛东寨港地区获得的248cm长的岩芯元素地球化学分析结果和AMS14C测试结果,辨识出1605年历史地震事件的沉积学证据.岩芯沉积物地球化学元素特征反映了从陆相沉积向海相沉积的转变,对海南岛东寨港地震陷落事件有明显的沉积响应.
According to the sedimentary characteristics of the CD core and the analysis results about the grain seize and elements,the geochemical records of the historical earthquake was presented in this paper. Rapid changes of the geochemical elements occurred at 160～180 cm of CD core and which indicated the environment changed quickly from terrestrial to marine environment.
