摘要:
本文以孟塞尔色标（Munsell Scale）为基准,描述了渤海南部海域海底沉积物的颜色特征及分布规律。研究海域内3个色别的沉积物颜色出现10YR,5Y,5YR。从Eh,Fe3+/Fe2+比值、有机质含量等化学要素的变化探讨了沉积物颜色的形成机制及其代表的沉积环境,提出本海域内可用黄河沉积物的特征颜色初步确定黄河水下三角洲的界线。

COLOR VARIATION OF SURFACE SEDIMENT IN SOUTH BOHAI SEA
Abstract:
Surface sedimentary color investigation was carried out in 1985-1987 by the Sino-American Yellow River estuary dynamics and marine geology work unit in the south Bohai sea. There are three kinds of color existing in the south Bohai sea: 10YR(6/2-5/4), 5Y(2/1-4/1), 5YR(4/2-3/2). The different sediment colors are discussed in this paper to determine the boundary of Yellow River subaqueous delta and different sedimentary environments.
Key words:  Sedimentary color, Varication of color, Sedimentary evnironment
