本文通过对不同水深区沉积物中组分、生物面貌、矿物、CaCO3含量和碳酸钙溶解率等特征的分析和对比,把本区碳酸钙溶解深度带划分为碳酸钙溶跃面(小于3700m)、弱溶带(3700~4800m)、强溶带(4800~5200m)和全溶带(大于5200m)。提出本海域碳酸钙补偿深度界面约在5200m。文中还阐述了不同碳酸钙溶解带及其沉积物特征,认为造成这种特征的主要原因是随着水深变化碳酸钙溶解程度不同以及与南极底层流等因素的影响有关。
Based on the analysis and comparison of the composition, biological appearance, mineral, CaCO3 content and dissolution rate of calcium carbonate in sediments from different water depths, the dissolution zone of calcium carbonate in this area is divided into calcium carbonate surface (less than 3700m) , Weak dissolving zone (3700 ~ 4800m), strong dissolving zone (4800 ~ 5200m) and total dissolving zone (more than 5200m). Proposed in this area of calcium carbonate compensation depth interface is about 5200m. In this paper, the characteristics of different dissolution zones of calcium carbonate and its sediments are also described. The main reason for this feature is that the dissolution of calcium carbonate varies with the depth of water and the influence of laminar flow and other factors.
