According to the chemical exploratory data of the Guilaizhuang gold deposit, W, As and Sb, the closest regional chemicalexploratoryelements to Au, were selected as regional variables to study the spatial distribution of Auanomaly with cokrig ing. Based on the spatial structure analysis of the four regional variables, their spatial structure models were built and the distribution of Au was estimated. From the study the authors find that there are quite a few Auanomalies in the study area, and the ore prospects are good.
