摘要
莱州湾沿岸是我国沿海高矿化度地下卤水的主要分布区,以在卤水分布区所钻取的LZ908孔为研究对象,根据沉积物的粒度、含水率、微体古生物等特征,分析卤水的富集层位、卤水含水层和隔水层的沉积特征、卤水形成前后的古海洋环境变化,通过分析得到卤水主要赋存于海相砂层中,形成于海侵后期的海退阶段。
The coastal area around the Laizhou Bay is one of the regions where the underground highly-mineralized brine are distributed in China.The sediment samples are collected from the LZ908 drill hole in the brine-distributed area of Laizhou for the related studies.Based on the characteristics of the sediment granularity,the aqueous content,and the micropaleontology,the analysis is concentrated at the depths of the brine-enriched layer,the sedimentation characteristies respectively in the brine aquifers and in the impervious layers,and the palaeo-oceanic environmental variation before and after the brine formation.It is learnt from the analysis that the brine is mainly stored in the sandy layer of sea facies,and formed in the regression phase of the later transgression.
