自发现大洋锰结核以来,围绕着分散于洋底的巨量锰结核的动向、探究其化学成分各组分的来源,锰结核的生长速率及开发利用等问题,引起了许多国家科学家的关注。根据过去大洋锰结核的化学成分分析,Mekelvey(1983)指出,在锰结核中可测出56种化学元素的含量,他列举了其中含有率超过0.01％的28种元素。但锰结核中痕量铯的含量分布迄今尚未见到报道。Folsom曾研究过太平洋(28°N,122°W)中溶解铯的垂直分布,提出铯在表层
Since the discovery of oceanic manganese nodules, many national scientists have been concerned about the trends of the massive manganese nodules dispersed in the ocean floor, the sources of their chemical composition, the growth rate of manganese nodules, and their exploitation and utilization. Based on past chemical compositional analysis of oceanic manganese nodules, Mekelvey (1983) pointed out that 56 chemical elements can be detected in manganese nodules and that he lists 28 elements with a content of more than 0.01%. However, the content of trace cesium in manganese nodules has not yet been reported. Folsom studied the vertical distribution of dissolved cesium in the Pacific Ocean (28 ° N, 122 ° W), suggesting that cesium is present on the surface
