Distribution of Calcium Carbonate and Its Controlling Factors in Surface Sediments of the South China Sea

摘要

摘要: 通过测定南海213个表层沉积物样品中的碳酸钙含量, 综合分析整个南海海域碳酸钙含量分布特征及其控制因素.结果表明, 不同的区域海洋环境, 控制表层沉积物中碳酸钙含量变化的因素也不尽相同: 大陆架区, 碳酸钙含量主要受陆源非碳酸盐物质的稀释作用而较低; 大陆坡区, 碳酸钙因丰富的物源量、低的陆源物质输入量和弱的碳酸钙溶解作用等因素而呈较高含量; 深海盆区, 碳酸钙含量因强烈的溶解作用而较低.根据碳酸钙含量在南海整个表层沉积物中的分布趋势, 推测南海纬度14°N以北的海域碳酸钙补偿深度(CCD)为3700m左右, 纬度14°N以南的海域CCD为4000m左右.Pearson相关分析表明, 南海表层沉积物中钙质超微化石对碳酸钙的含量分布具有较高的贡献率.

Abstract: This paper determines the calcium carbonate content in 213 surface sediment samples from the South China Sea (SCS) in order to have a comprehensive analysis of the distribution character of calcium carbonate and its controlling factors in surface sediments of the SCS. The results show that there are different influence parameters in distributions of calcium carbonate in various regions: In the shelf, calcium carbonate contents are low owing to largely terrigenous material input; In the slope, calcium carbonate contents are high due to abundant supply of calcareous organisms, low terrigenous material input and weak dissolvability; In the deep basin, calcium carbonate contents are very low because of strong dissolvability. According to the distribution character of calcium carbonate content in surface sediments in the SCS, it is concluded that the carbonate compensation depths (CCD) are about 3700m in the north of 14°N and about 4000m in the south of 14°N. Pearson Correlation shows that calcareous nannofossils had significant contribution to the calcium carbonate content in surface sediments in the SCS.
