Comparing linear and non-linear kriging for grade prediction and ore/waste classification in mineral deposits
(Taylor and Francis Ltd., 2019)
© 2017, © 2017 Informa UK Limited, trading as Taylor & Francis Group. Ore/waste classification and economic evaluations of mineral deposits rely on the grade of elements of interest, which must be predicted as accurately ...

Ordinary multigaussian kriging for mapping conditional probabilities of soil properties
(ELSEVIER, 2006-05)
This paper addresses the problem of assessing the risk of deficiency or excess of a soil property at unsampled locations, and more generally of estimating a function of such a property given the information monitored at ...
Estimation or simulation? That is the question
(SPRINGER, 2008)
The issue of smoothing in kriging has been addressed either by estimation or simulation. The solution via estimation calls for postprocessing kriging estimates in order to correct the smoothing effect. Stochastic simulation ...

Geostatistical estimation of mineral resources with soft geological boundaries: a comparative study
(SOUTH AFRICAN INST MINING METALLURGY, 2006-08)
Mineral resource evaluation requires defining geological domains that differentiate the types of mineralogy, alteration and lithology. Usual practice is to consider the domain boundaries as hard, i.e. data from across the ...
Multi-Gaussian kriging: a practice to enhance delineation of mineralized zones by Concentration–Volume fractal model in Dardevey iron ore deposit, SE Iran
(Elsevier, 2015)
The purpose of this study is to identify the effect of ordinary and simple multi-Gaussian kriging (oMK, sMK) estimation methods for the delineation of iron mineralized zones based on subsurface data using Concentration-Volume ...
