海洋地质与第四纪地质

<正>青岛洋河下游地区指胶州湾西岸,属洋河、漕汉河、岛耳河等汇合而成的第四系冲、洪积平原.由于上述诸河流的多次变迁改道,第四系沉积物变化复杂,致使电测深曲线类型多变,给定性和定量解释造成困难.但其计算结果经修正后,得出较好的地质解释效果.物探推断的上、下沙层和第四系总厚度,经14个钻孔的验证,最大误差为1.6米,多数小于1米,物探资料的地质解释与钻探结果吻合较好,基本完成了地质设计提出的任务与要求.一、地质及地球物理概况本区地层:基岩主要为白垩系青山组(K_1g)火山碎屑岩或王氏组(K_2w)砂、砾岩.

Because of the changing of several small river channels (the Yanhe River, Chaowen River and Daoer River), the Quaternary beds in the lower reaches of the modern Yanhe River vary complicately in thickness and geographical distribution. Based upon explaining the data of electric measurment in this area, we understand changes of the Quaternary various beds in thickness and distribution of water-bearing sand beds, providing geophysical data for prospecting fresh water,
