Abstract The Trans-Hudson Orogen (THO) of North America is one the earliest orogens in Earth's history that evolved through a complete Wilson Cycle. It represents c . 150 Ma opening Manikewan Ocean, from 2.07–1.92 Ga, followed by its demise interval 1.92–1.80 during final phase growth Supercontinent Columbia (Nuna). characterized three lithotectonic divisions: (i) Churchill margin (or peri-Churchill); (ii) Reindeer Zone; and (iii) Superior peri-Superior). peri-Churchill realm records...
Earth's near-surface mineralogy has diversified over more than 4.5 b.y. from no a dozen preplanetary refractory mineral species (what have been referred to as "ur-minerals" by Hazen et al., 2008) ~5,000 (based on the list of minerals approved International Mineralogical Association; http://rruff.info/ima). This dramatic diversification is consequence three principal physical, chemical, and biological processes: (1) element selection concentration (primarily through planetary differentiation...
Abstract. Three-dimensional geological modelling algorithms can generate multiple models that fit various mathematical and geometrical constraints. The results, however, are often meaningless to experts if the do not respect accepted principles. This is problematic as use of expected for downstream purposes, such hazard risk assessment, flow characterization, reservoir estimation, storage, or mineral energy exploration. Verification reasonableness therefore important. If implausible be...
Abstract Three-dimensional structural geomodels are increasingly being used for a wide variety of scientific and societal purposes. Most advanced methods generating these models implicit approaches, but they suffer limitations in the types interpolation constraints permitted, which can lead to poor modeling structurally complex settings. A geometric deep learning approach, using graph neural networks, is presented this paper as an alternative classical that driven by through training...
Abstract Regional‐scale geologic structures characteristic of mantle lithosphere within cratons found in continent interiors are interpreted using geo‐registered diverse data sets from the Slave craton northwest Canada. We developed and applied a new method for mapping seismic discontinuities three dimensions multiyear observations at sparse, individual broadband receivers. New, fully 3‐D conductivity models used all available magnetotelluric data. Discontinuity surfaces were with previously...

Geological rules will be encoded to ensure proper extraction.Geological Event Loop time-aware the event manager capturing topological time relationship between objects structural eventsForward inverse modelling: we encode context account...
ABSTRACT Exploration for deep-seated mineral deposits in mature mining camps requires integration of large and heterogeneous spatial data-sets. Traditionally, geological, geochemical, geophysical observations are acquired, processed analysed independently within separate contexts or more commonly, geochemical data, non-spatial feature space. Although methodological developments still progress, 3D GIS (geographic information system) technologies already provide powerful tools that can be used...
Abstract. Implicit neural representation (INR) networks are emerging as a powerful framework for learning three-dimensional shape representations of complex objects. These can be used effectively to model geological structures from scattered point data, sampling interfaces, units, and structural orientations. The flexibility scalability these provide potential integrating many forms data knowledge that classical implicit methods cannot easily incorporate. We present an modelling approach...
The hydrothermal system architecture related to the formation of contemporaneous Au-bearing Horne and Quemont volcanogenic massive sulfide (VMS) deposits was visualized by employing kriging methods map whole-rock oxygen isotope compositions, zones silica addition loss, water contents in two- three-dimension. Zones alteration were mapped three-dimensions vicinity steeply dipping deposit, depths as much 2 km. In all, nearly 300 samples analyzed for isotopes supplemented previously published...
We have developed a regional-scale 3D geologic model, highlighting the Mesoproterozoic Sullivan time horizon (approximately 1470 Ma) throughout Purcell Anticlinorium in East Kootenay region. This geospatial model of region is constrained with an extensive surface and subsurface database stratigraphic, structural, geophysical observations distributed study area. modeling exercise was conducted over four-year period from 2011 to 2015 which several iterations were produced. The final includes...
Stratigraphic surfaces implicitly modelled using a generalized interpolation approach in various geological settings is presented to demonstrate its modelling capabilities and limitations. The provides useful mathematical framework continuous from scattered data consisting of the following constraints: contact locations planar orientations. Examples are show effectiveness method generating plausible representations structures sparse environments. One major advantages implicit surface has...
