深海碳酸盐溶解作用是海洋沉积学研究的重要内容之一。众所周知有孔虫遗壳是深海底质碳酸盐沉积的主要来源,浮游有孔虫壳的存在与沉积物中碳酸钙的含量密切相关。了解浮游有孔虫的被溶蚀情况,对了解深海碳酸盐溶解作用具有重要意义。 本文根据南海中部海区表层沉积物中浮游有孔虫的分布和碳酸钙含量的分析,对该海区的碳酸盐溶解作用和主要界面的深度作初步探讨。
Deep-sea carbonate dissolution is one of the important contents of marine sedimentology. It is well-known that foraminifera is the main source of deep-sea carbonate deposition. The presence of planktonic foraminifera is closely related to the content of calcium carbonate in sediments. To understand the dissolution of planktonic foraminifera is of great significance for understanding the dissolution of deep-sea carbonate. Based on the distribution of planktonic foraminifera and the content of calcium carbonate in the surface sediments of the central South China Sea, the paper discussed the dissolution of carbonate and the depth of the main interface in this area.
