浮游有孔虫,是现代大洋底碳酸盐沉积的主要来源,也是研究深海碳酸盐溶解作用的良好依据。当浮游有孔虫壳在海洋沉积物中具有一定数量(>30%)时,这种沉积物便被称为“抱球虫软泥”或“浮游有孔虫软泥”。这种 Planktonic foraminifera is the main source of modern oceanic carbonate deposition and a good basis for studying the dissolution of deep-sea carbonate. When the planktonic foraminifera shell has a certain amount (> 30%) of the marine sediment, this sediment is called “coccidian slime” or “planktonic foraminifera”. This
