Dual Random Fields and their Application to Mineral Potential Mapping
Álvaro I. Riquelme
In various geosciences branches, including mineral exploration, geometallurgical characterization on established mining operations, and remote sensing, the regionalized input varia…
Multivariate Simulation Using A Locally Varying Coregionalization Model
Alvaro I. Riquelme, Julian M. Ortiz
Multivariate spatial modeling is key to understanding the behavior of materials downstream in a mining operation. The ore recovery depends on the mineralogical composition, which n…
A Riemannian Approach to Multivariate Geostatistical Modeling
Alvaro Riquelme
In geosciences, the use of classical Euclidean methods is unsuitable for treating and analyzing some types of data, as this may not belong to a vector space. This is the case for c…
A general approach to the assessment of uncertainty in volumes by using the multi-Gaussian model
Alvaro I. Riquelme, Julian M. Ortiz
The goal of this research is to derive an approach to assess uncertainty in an arbitrary volume conditioned by sampling data, without using geostatistical simulation. We have accom…
