  3. Geologic modelling - Wikipedia

    en.wikipedia.org/wiki/Geologic_modelling

    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.

  4. QAPF diagram - Wikipedia

    en.wikipedia.org/wiki/QAPF_diagram

    QAPF diagram for classification of plutonic rocks. A QAPF diagram is a doubled-triangle plot diagram used to classify intrusive igneous rocks based on their mineralogy.The acronym QAPF stands for "Quartz, Alkali feldspar, Plagioclase, Feldspathoid (Foid)", which are the four mineral groups used for classification in a QAPF diagram.

  5. Mineral resource estimation - Wikipedia

    en.wikipedia.org/wiki/Mineral_resource_estimation

    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.

  6. Crystallographic database - Wikipedia

    en.wikipedia.org/wiki/Crystallographic_database

    Crystal structure visualization can be integrated into a crystallographic database. Alternatively, the crystal structure data are exchanged between the database and the visualization software, preferably using the CIF format. [33] Web-based crystallographic databases can integrate crystal structure visualization capability. [34]

  7. Petrogenetic grid - Wikipedia

    en.wikipedia.org/wiki/Petrogenetic_grid

    Experimentally determined mineral or mineral-assemblage stability ranges are plotted as metamorphic reaction boundaries in a pressure–temperature cartesian coordinate system to produce a petrogenetic grid for a particular rock composition. The regions of overlap of the stability fields of minerals form equilibrium mineral assemblages used to ...

  9. Compatibility diagram - Wikipedia

    en.wikipedia.org/wiki/Compatibility_diagram

    In metamorphic geology, a compatibility diagram shows how the mineral assemblage of a metamorphic rock in thermodynamic equilibrium varies with composition at a fixed temperature and pressure. Compatibility diagrams provide an excellent way to analyze how variations in the rock's composition affect the mineral paragenesis that develops in a ...
