浦东ＹＡ孔浅地层剖面中微量元素变化的分析结果表明， Ｂ含量和Ｂ／Ｇａ， Ｓｒ／Ｂａ， Ｃｌ／Ｂｒ比值是反映古水体盐度的灵敏指示剂， 据此建立的ＹＡ孔古盐度指数变化曲线显示， 该地区近数千年来曾发生过多次百年尺度的盐度波动事件， 并可能与同期海面波动引起的海水进退直接相关。这一情况说明， 滨海地区沉积地层中的微量元素是海面变化研究的良好的代用指标。
The analysis results of trace elements in the shallow stratigraphic section of YA in Pudong show that the B content and B / Ga, Sr / Ba and Cl / Br ratios are sensitive indicator of the salinity of paleo-water bodies. The paleosalinity The exponential curve shows that there have been several hundred-year-scale salinity fluctuations in the region in recent millennia and may be directly related to the sea-level rise and fall caused by the sea surface wave over the same period. This shows that the trace elements in the sediments of the coastal area are a good proxy for the study of changes in the sea surface.
