Geostatistical Simulation of Cross-Correlated Variables: a Case Study through Cerro Matoso Nickel-Laterite Deposit

Madani, Nasser; Ortiz, Julian (The 26th International Symposium on Mine Planning and Equipment Selection, 2017-08-31)

Geostatistical methods have been increasingly used as powerful techniques for predicting spatial attributes and modelling the uncertainty of predictions in un-sampled locations, especially through multi-element deposits. ...
A HIERARCHICAL COSIMULATION ALGORITHM INTEGRATED WITH AN ACCEPTANCE– REJECTION METHOD FOR THE GEOSTATISTICAL MODELING OF VARIABLES WITH INEQUALITY CONSTRAINTS

Madani, Nasser; Abulkhair, Sultan (Springer, 2020-07)

This work addresses the problem of the cosimulation of cross-correlated variables with inequality constraints. A hierarchical sequential Gaussian cosimulation algorithm is proposed to address this problem, based on ...
