摘要
总结了已有富钴结壳资源量评价方法,分析了这些方法存在的问题,在此基础上提出将分形理论应用于富钴结壳资源量评价方面。根据我国太平洋海山的数据,研究了富钴结壳的丰度、厚度和金属等量品位(指钴等量品位,CEG)与水深、坡度、坡向的分形特征,结果显示富钴结壳的丰度、厚度和金属等量品位的多阶累计和呈多重分形分布。这一结果可以用在资源量评价时地质块段的划分上,为地质块段的划分提供定量依据。
Based on summarizing the known evaluation methods of the cobalt-rich incrustation resource quantity, this paper analyses the existing problems of these methods, then brings forwards that fractal theory can be used in resource quantity calculating. According to the data of the sea mountains in Pacific, the fractal characters of the abundance, thickness and CEG with water depth, gradient and its directions have been researched. The results shows that the multiphase pluses of those data are multifractals. According to the results, the geologic block can be divided quantitatively when the resource quantity is evaluated.
