Curvature Attribute from Surface-Restoration as Predictor Variable in Kupferschiefer Copper Potentials

Autor: Jean-Jacques Royer, Pablo Mejia-Herrera, Guillaume Caumon, Alain Cheilletz

Publikováno v: Natural Resources Research. 24:275-290

This work explains a procedure to predict Cu potentials in the ore-Kupferschiefer using structural surface-restoration and logistic regression (LR) analysis. The predictor in the assessments are established from the restored horizon that contains the
