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 ...
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 ...
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 ...
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 ...
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 ...
A geostatistical approach to measure the consistency between geological logs and quantitative covariates
(Elsevier, 2017)
Core logging is the geological study, recording and classification of petrophysical attributes of drill hole samples, such as lithology, alteration or mineralogical assemblage. The geological logging is qualitative and ...
Risk quantification with combined use of lithological and grade simulations: Application to a porphyry copper deposit
(Elsevier Science BV., 2016)
The uncertainty in the recoverable tonnages and grades in a mineral deposit is a key factor in the decision-making process of a mining project. Currently, the most prevalent approach to model the uncertainty in the spatial ...
Subsurface geological modeling of Corrientes province (NE Argentina) and its relationships with the Guaraní Aquifer system function
(Pergamon-Elsevier Science Ltd, 2015-10)
From the integration results of geological and geophysical data, a subsurface geological model of the Corrientes province (Argentina) that allows visualizing its deep geological structure and how it affected the Guaraní ...
Plurigaussian modeling of geological domains based on the truncation of non-stationary Gaussian random fields
(Springer, 2017)
The plurigaussian model is used in miningengineering, oil reservoir characterization, hydrology andenvironmental sciences to simulate the layout of geologicaldomains in the subsurface, while reproducing their spatialcontinuity ...
