Abstract

Abstract

The concept of coregionalization and coregionalized variable are described. The cross-moments and its properties (such as cross-covariance and cross-variogram) are discussed in more detail. In the view of above analysised, the cokriging (include cokriging systems, cokriging variance and so on) is studied mainly, and the mean grade of gold in a block is estimated. This method makes use of estimated level of Au and Ag in neighborhood.
