近年来,沉积磷酸盐方法对古盐度的测定,开始运用于沉积相方面的研究。占盐度的含量及其变化,在一定程度上有助于识别海相、陆相和过渡相地层,提供对沉积环境和古地理的认识,特别在古生物和古生态资料欠缺的情况下,将要有助于岩相的划分。 为了摸索沉积磷酸盐方法测定古盐度在沉积相方面研究的运用,我们曾用这一方法,对长江三角洲近代(全新世)沉积和苏北高邮凹陷戴南组上段以及三垛组下段等沉积进行研究和探讨。由于分析样品不多,同时经验不足,不妥之处在所难免,盼批评指正。
In recent years, sedimentary phosphate method for measuring ancient salinity, began to apply in sediment research. The content of salinities and their variations account for a certain extent, helping to identify marine, continental and transitional facies strata and provide understanding of sedimentary environment and palaeogeography. In particular, in the absence of paleontological and paleoecological information, Contribute to the division of lithofacies. In order to find out the application of sedimentary phosphate determination in the study of sedimentary facies, we used this method to study the sedimentation of modern (Holocene) deposits in the Yangtze River Delta and the upper part of the Dainan Formation and the lower part of the Sandun Formation in the Gaoyou depression of northern Jiangsu Province Conduct research and discussion. Due to the small number of analysis of samples, at the same time, lack of experience, the inappropriate place is inevitable, hope criticism and correction.
