Geological modelling and validation of geological interpretations via simulation and classification of quantitative covariates
(MDPI AG, 2018)
This paper proposes a geostatistical approach for geological modelling and for validating an interpreted geological model, by identifying the areas of an ore deposit with a high probability of being misinterpreted, based ...

Geostatistical modeling of the geological uncertainty in an iron ore deposit
(Elsevier, 2017)
This paper addresses the problem of quantifying the joint uncertainty in the grades of elements of interest (iron, silica, manganese, phosphorus and alumina), loss on ignition, granulometry and rock types in an iron ore ...
Incorporating the uncertainty in geological boundaries into mineral resources evaluation
(2007)
Geological modelling is a key step prior to grade estimation in a mineral deposit and consists of a deterministic partitioning of the deposit into sub-domains called 'geological units', each with relatively homogeneous ...
Reinterpretación geológica utilizando la tecnología de búsqueda de petróleo y gas (OFT)
(Fundación Universidad de América, 2016-08-24)
El presente proyecto se desarrolló con la finalidad de brindar una solución a la incertidumbre en la identificación de los límites del yacimiento y la posible localización de pozos de desarrollo para la zona del Bloque La ...
Modelling geotechnical heterogeneities using geostatistical simulation and finite differences analysis
(MDPI, 2018)
Modelling a rock mass in an accurate and realistic way allows researchers to reduce the uncertainty associated with its characterisation and reproduce the intrinsic spatial variability and heterogeneities present in the ...
3D GIS-based visualisation of geological, hydrogeological, hydrogeochemical and geothermal models
(E Schweizerbartsche Verlags, 2016-12)
An integrated methodology is proposed for the 3D visualisation of underground resources related to groundwater. A set of tools named HEROS3D was developed in a GIS environment to support the generation of 3D entities ...
Indicator variograms as an aid for geological interpretation and modeling of ore deposits
(MDPI AG, 2017)
Geostatistics offers a set of methods for modeling, predicting, or simulating geological domains in space. In addition of being an input of some of these methods, indicator direct and cross-variograms convey valuable ...
Stochastic rock type modeling in a porphyry copper deposit and its application to copper grade evaluation
(Elsevier, 2015)
An accurate definition of geological domains that differentiate the types of mineralogy, alteration and lithology is a critical step in mineral resources and ore reserves evaluation. Deterministic models define just one ...
