| 摘 要： | 前人在1987年就开始对福建深沪海底古森林遗址进行了研究,本文在前人调查研究工作的基础上,通过钻探、坑探、14C测年、微体古生物分析等工作,探讨了福建深沪海底古森林遗址古地理环境及海陆变迁情况。该海底古森林生长于全新世长乐组冲洪积地层中,距今约7 000~7 700 a,为湿热气候环境。牡蛎的生长环境为滨海泥滩环境,距今约26 000~27 000 a左右和距今约4 500 a,处于海侵影响范围。研究表明该处经历过多次海陆变迁。

| Abstract: | Based on the predecessor's studies on submarine forest in Shenhu in 1987,drilling hole date,~(14)pitting information and micropaleontology analysis,this paper discussed about the ancient geographical environment and sea-land transition situation of ancient submarine forest in Shenhu Bay,Fujian province.The results showed that ancient submarine forest grew in alluvial deposit in Holocene Changle group 7000~7700 years ago,under damp and hot climate environment oyster was growing in littoral mud environment about 26,000~27,000 years ago or in marine invasion environment about 4500 years(BP) ago.These indicate that the place has experienced sea-land transition for many thimes. |
