3D implicit modeling of the Sishen Mine: new resolution of the geometry and origin of Fe mineralization

3D Modeling of the Epembe (Namibia) Nb-Ta-P-(LREE) Carbonatite Deposit: New Insights into Geometry Related to Rare Metal Enrichment

“…Rule-based implicit modeling (see [34]) with SKUA-GoCad allows the user to model different complex geologic objects (e.g., layers, faults, intrusions) based on different classes of objects (e.g., point sets, lines, surfaces, voxels, Stratigraphic Grids (SGrids)). Homogenous or heterogeneous data like well-based information (e.g., geology, logs of properties) or grid-based 2D and 3D information (geological cross-sections and geochemical data) were imported as point sets.…”

3D structural control and spatial distribution of Zn-Pb-Cu grades in the Palmeirópolis VMS deposit, Brazil

“…3D geological modelling is often related to mineral resources evaluation, but this application is far away to be unique, with considerable examples in the literature using it to understand better the formation and genesis of mineral deposits (Basson et al 2016;Stoch et al 2018;de Oliveira et al 2019;Cowan 2020;de Oliveira et al 2020de Oliveira et al , 2021. The Palmeirópolis deposit is an interesting case study to be modelled in 3D because it is a deformed Mesozoic VMS deposit, with distinct ore bodies occurring in different host rocks, shapes, and structural controls, making it possible to compare them with each other and to other VMS deposits around the world.…”

3D implicit modeling applied to the evaluation of CO2 geological storage in the shales of the Irati Formation, Paraná Basin, Southeastern Brazil

“…However, its use in the other applied areas of geosciences is in growth stages. Few recent examples of 3D implicit geological modeling include iron deposits, as in the Sishen Mine, South Africa (Stoch et al 2018), base metal deposits, as in Falun, Sweden (Kampmann et al 2016), Flin Flon, Canada (Schetselaar et al 2016), Shalipayco, Peru (de Oliveira et al 2021), gold deposits, as Navachab, Namibia (Vollgger et al 2015), La Colossa, Colombia (Naranjo et al 2018), Sigma-Lamaque, Canada (Cowan 2020), and geothermal reservoirs (Alcaraz et al 2015), amongst others.…”

“…Recent examples of 3D implicit geological modeling include iron deposits (e.g. Sishen Mine, South Africa), 18 base metal deposits (e.g., Falunin in Sweden, Flin Flon in Canada, and Shalipayco in Peru), [19][20][21] gold deposits (e.g., Navachab in Namibia, La Colossa in Colombia, and Sigma-Lamaque in Canada), [22][23][24] and geothermal reservoirs, 25 among others. The 3D implicit modeling expands the analysis of conventional geological data by visualizing continuities, groupings, and spatial trends, as well as geometries of geological bodies or units, structural geological framework, and variation of geochemical contents or any other numerical or categorical parameters in geosciences.…”
