摘要: |
为确认太湖本身和其周围地区是否有全新世海相沉积物, 对其沉积物中的微古生物化石的性质与特征, 以及它与沉积物所含的盐度、层间水、岩相等的关系进行了研究, 并通过古遗址分布情况、古地理环境等因素的调查, 确认本区的全新世生物坪葬群是长江涨潮流带来异地埋葬的产物, 不能作为海相地层的唯一依据。 |

Abstract: |
One of the fairly available ways in identifying and recognizing marine and continental rocks is to study the nature and feature of the sediments which consist of micropaleontclogy. When identifying the Holocene marine and continental strata of Taihu Lake, situated on the south of the Yangtze Delta, one should take in-to account the possibility of the allochthococnosis microfossils carried by the Yangtze flood tidal current to the studied area. Consequently, the thanatococnosis which appears in the Holocene rocks can not be considered as the only evidence of marine ones. |
