沉积物中的碳酸盐组分在形成条件和影响因素等方面都具有特殊性,能反映所在环境和相的特征。东海表层沉积物中有较丰富的碳酸盐产出,最高含量达样品总重的51.2％,或占总体积的70％。这些碳酸盐的成因类型、矿物成分、分布规律对了解东海海域的现代沉积作用及控制因素有重要意义,并能对产于类似环境的古钙质沉积的研究起借鉴作用。眭良仁等曾对东海碳酸盐作过研究,本文将对黄海南部至东海北部陆架区(30°—35°N,122°—128°E)表层沉积中的碳酸盐组分及其形成作用作一论述。
The carbonate components in sediments are special in forming conditions and influencing factors, which can reflect the environment and the characteristics of the facies. The surface sediments in the East China Sea are rich in carbonate production, the maximum content of 51.2% of the total sample weight, or 70% of the total volume. The genetic types, mineral compositions and distribution of these carbonates are of great significance for understanding the modern sedimentation and controlling factors in the East China Sea, and can be used for reference to the study of palecalcium deposition in similar environments. Ying Liang et al. Studied the carbonate in the East China Sea. In this paper, the carbonate components in the surface sediments of the northern Yellow Sea to the northern shelf of the East China Sea (30 ° -35 ° N, 122 ° -128 ° E) and their formation Role of a discussion.
