THE APPLICATION OF VARIOGRAM IN DAHONGSHAN IRON ORE DEPOSIT IN YUNNAN PROVINCE

The variogram is core content and basic tool of geostatistics.It can preferably research basic characteristics of regionalized variables of one ore deposit,especially it can reflect structrural chang of the variables by random chang of the variables.On the base of intruducing to the concept of variogram and researching to the geological Characteristics of Dahongshan Iron Ore Deposit,this paper has computed the variogram of Dahongshan Iron Ore Deposit,and analysed those computing results.
