CC西区多金属资源评价的协同区域化理论和方法

Co-Kriging model of manganese nucleus mineral resource evoluation in the CC region of the Pacific Ocean

详细介绍矿产资源评价的协同区域化理论和协同克立格方法,同时结合大洋CC西区锰结核资源评价工作,探讨其在大洋矿产资源评价中的应用.在CC西区的锰结核矿石中铜、钴、镍是三种相关而经济价值又不同的金属,同时矿石的分布水深也是制约开采成本的重要因素.利用协同克立格方法建立资源评价模型,估计上述区域化变量在空间中的有利组合分布样式来圈定更加有潜力的矿区位置以及估计资源量,达到资源定位预测和定量评价的目的.这种方法对锰结壳资源评价同样有效.

The co-Kriging method and its application to mineral resource evaluation of manganese nucleus in the CC region of the Pacific Ocean are introduced in detail.Cu,Co and Ni are three metal elements which depend on each other and are intruduced in detail have different economical values.Depth of seabed is another importance characteristics related to exploitation cost. Using co-Kriging model evaluates manganese nucleus mineral resource amount, estimates space distribution pattern of those characteristics and their combination, and delimits potential and amount of manganese nucleus mineral resource, predicts and evaluates mineral resource with Co ,Cu and Ni abundance. This method has the same availability with manganese crust
