3D structural geological modeling CGRE Institute, RWTH Aachen - Miguel de la Varga LGPL v3: Cross-platform: Python: Open-source implicit geological modeling that allows for automation of model construction and is aimed to enable the implementation of probabilistic machine-learning methods, e.g. for uncertainty analysis.
Geologists involved in mining and mineral exploration use geologic modelling to determine the geometry and placement of mineral deposits in the subsurface of the earth. Geologic models help define the volume and concentration of minerals, to which economic constraints are applied to determine the economic value of the mineralization.
The structural model, isostructural with the mineral akdalaite (Al 10 O 14 (OH) 2), contains 20% tetrahedrally and 80% octahedrally coordinated iron. Manceau et al. showed in 2014 [ 28 ] that the Drits et al. [ 12 ] model reproduces the PDF data as well as the Michel et al. [ 26 ] model, and he suggested in 2019 [ 20 ] that the tetrahedral ...
Mineral resource estimation is used to determine and define the ore tonnage and grade of a geological deposit, from the developed block model. There are different estimation methods used for different scenarios dependent upon the ore boundaries, geological deposit geometry, grade variability and the amount of time and money available.
For economic geology such as petroleum and mineral development, as well as research, modeling of structural geology is becoming increasingly important. 2D and 3D models of structural systems such as anticlines, synclines, fold and thrust belts, and other features can help better understand the evolution of a structure through time. Without ...
Once well logs are properly conditioned and edited, a petrophysical rock model is generated that can be used to derive the effective elastic rock properties from fluid and mineral parameters as well as rock structure information. The model parameters are calibrated by comparison of the synthetic to the available elastic sonic logs.
The relational database structure of PetDB is a sample-based implementation, and designed to accommodate chemical, isotopic and mineralogical data for any type of rock sample, along with essential metadata, which provide information about each sample (e.g. location and time of collection, taxonomy, petrographic description) and the data quality ...
Dana's classification [1] [2] is a mineral classification developed by James Dwight Dana. It is based on the chemical composition and structure of minerals. It is mainly used in English-speaking countries, especially in the United States. The mineral classification used by the International Mineralogical Association is the Nickel-Strunz ...
