并非所有大洋锰结核都具有开采价值,不同海区、不同类型的锰结核,其含矿性大不相同。本文根据中平洋海盆181个站位的锰结核样品化学分析数据和其他有关资料,通过概率统计和相关分析,讨论了锰结核中金属元素Mn、Fe、Cu、Co、Ni、Pb、Zn的概率分布和各元素的相关关系以及Mn/Fe比率的变化规律等地球化学特征,并在此基础上对锰结核的含矿性地球化学标志和物质来源进行了初步探讨。 资料分析表明,Mn/Fe比率参数可作为锰结核含矿性的地球化学标志,锰结核含矿物质的来源随赋存状况不同而不同。
Not all ocean manganese nodules have a mining value, different sea areas, different types of manganese nodules, their ore content is very different. Based on the chemical analysis data of manganese nodules at 181 stations in the Central Pacific Ocean basin and other relevant data, the relationship between the contents of Mn, Fe, Cu, Co, Ni, Pb and Zn in manganese nodules was discussed through probability statistics and correlation analysis Probability distribution and the relationship between the elements and the variation of Mn / Fe ratio and other geochemical characteristics, and on this basis, preliminary study of ore-bearing geochemical markers and material sources of manganese nodules. Data analysis shows that the Mn / Fe ratio can be used as the mineralization geochemical index of manganese nodules, and the source of manganese nodule minerals varies with the occurrence of ore deposits.
