| 摘 要： | 福建深沪湾海底古森林是强古地震遗迹。研究结果表明 ,全新世早期该处海底古森林生长在由松散的晚更新世含砾砂粘土构成的低凹洼地内。距今 70 0 0a左右的强古地震导致古森林沉没于海并形成泻湖环境 ,约距今 2 0 0 0a的又一次强古地震使海底古森林沉没到更深的海底 ,推测这两次古地震的震级都超过 7级 |

| Abstract: | The submerged paleo forest in Shenhuwan Bay, Fujian Province, is accepted to be the vestige of strong paleo earthquake. The fossil trees were formerly growing in low lying land filled with late Pleistocene gravel bearing sandy clay during Holocene. A strong earthquake occurred 7000 years B.P. had caused the subsidence of the trees onto the seafloor and the development of lagoon environment, while another strong earthquake occurred 2,000 years B.P. had given rise to the further subsidence of the tre |
