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 (3-D) geological structural modeling aims to determine information in a 3-D space using data (foliations and interfaces) topological rules as inputs. This is necessary any project which the properties of subsurface matters; they express our understanding geometries depth. For that reason, models have wide range practical applications including but not restricted civil engineering, oil gas industry, mining water management. These models, however, are fraught with...
Abstract The spatial relationship between different rock types and relevant structural features is an important aspect in the characterization of ore-forming systems. Our knowledge about this geological architecture often captured 3D models. Multiple methods exist to generate these models, but one problem remains: models contain significant uncertainties. In recent years, several approaches have been developed consider uncertainties prior parameters that are used create through use...
The increasing catalogue of high-quality ice-penetrating radar data provides a unique insight in the internal layering architecture Greenland ice sheet. stratigraphy, an indicator past deformation, highlights irregularities flow and reveals large perturbations without obvious links to bedrock shape. In this work, establish new conceptual model for formation process, we analysed at onset Petermann Glacier, North Greenland, created three-dimensional several distinct stratigraphic layers. We...
Abstract. In this contribution we introduce LoopStructural, a new open-source 3D geological modelling Python package (http://www.github.com/Loop3d/LoopStructural, last access: 15 June 2021). LoopStructural provides generic API for applications harnessing the core scientific libraries pandas, numpy and scipy. Six different interpolation algorithms, including three discrete interpolators 3 polynomial trend interpolators, can be used from same model design. This means that algorithms mixed...
Abstract New petrological and geochronological data are presented on high‐grade ortho‐ paragneisses from northwestern Ghana, forming part of the Paleoproterozoic (2.25–2.00 Ga) West African Craton. The study area is located in interference zone between N–S NE – SW ‐trending craton‐scale shear zones, formed during Eburnean orogeny (2.15–2.00 Ga). High‐grade metamorphic domains separated low‐grade greenstone belts by high‐strain including early thrusts, extensional detachments late‐stage...
We have developed a joint geophysical inversion workflow that aims to improve subsurface imaging and decrease uncertainty by integrating petrophysical constraints geologic data. In this framework, probabilistic modeling is used as source of information condition the spatially derive starting models. The then uses measurements constrain values retrieved inversion. different sources are integrated into least-squares framework capture integrate related geophysical, petrophysical, This allows us...
We solve the 3-D gravity inverse problem using a massively parallel voxel (or finite element) implementation on hybrid multi-CPU/multi-GPU (graphics processing units/GPUs) cluster. This allows us to obtain information density distributions in heterogeneous media with an efficient computational time. In new software package called TOMOFAST3D, inversion is solved iterative least-square or gradient technique, which minimizes L1-/L2-norm–based misfit function. It drastically accelerated either...
