莱州湾、渤海湾及渤海中央盆地沉积物岩芯地球化学的初步研究

A Preliminary Study on Geochemistry of Sediment Cores from Laizhou Bay, Bohai Bay and the Central Basin of Bohai Sea

本文对莱州湾、渤海湾、渤海中央盆地的海洋底质沉积环境进行了研宄,通过对17柱沉积物岩芯样品中Fe,Al,Mn,Ti的测定和分析,论述了四元素在底质表层沉积物中及在岩芯沉积物中的含量和分布规律,用数理统计的方法分析了渤海中央盆地Fe,Al,Mn,Ti的丰度值,为渤海环境背景值及环境背景历史的研究提供了重要参数。

In this paper, studies are made on marine sedimentary environments in Laizhou Bay, Bohai Bay and the Central Basin of the Bohai Sea. Through determinations of Fe, Al. Mn and Ti in 17 core samples, their concentrations and distributions in the surficial sediments and the cores are discussed. Analysis is made by mathematical statistics of the concentrations of these 4 elements in the Central Basin of the Bohai Sea. The results obtained in the present paper provide important reference date for the environmental backgound values and history of the Bohai Sea.
