  2. Prospecting - Wikipedia

    en.wikipedia.org/wiki/Prospecting

    Prospecting is the first stage of the geological analysis (followed by exploration) of a territory. It is the search for minerals, fossils, precious metals, or mineral specimens. It is also known as fossicking . Traditionally prospecting relied on direct observation of mineralization in rock outcrops or in sediments.

  3. Geomechanics - Wikipedia

    en.wikipedia.org/wiki/Geomechanics

    Geomechanics (from the Greek γεός, i.e. prefix geo- meaning "earth"; and "mechanics") is the study of the mechanical state of the Earth's crust and the processes occurring in it under the influence of natural physical factors. It involves the study of the mechanics of soil and rock.

  4. Gold prospecting - Wikipedia

    McKelvey diagram. A McKelvey diagram or McKelvey box is a visual representation used to describe a natural resource such as a mineral or fossil fuel, based on the geologic certainty of its presence and its economic potential for recovery. The diagram is used to estimate the uncertainty and risk associated with availability of a natural resource ...

  6. Placer deposit - Wikipedia

    en.wikipedia.org/wiki/Placer_deposit

    Heavy minerals (black) forming placers along ripple marks. In geology, a placer deposit or placer is an accumulation of valuable minerals formed by gravity separation from a specific source rock during sedimentary processes. [1] The name is from the Spanish word placer, meaning " alluvial sand". Placer mining is an important source of gold, and ...

  7. Geological survey - Wikipedia

    en.wikipedia.org/wiki/Geological_survey

    A geological survey is the systematic investigation of the geology beneath a given piece of ground for the purpose of creating a geological map or model. Geological surveying employs techniques from the traditional walk-over survey, studying outcrops and landforms, to intrusive methods, such as hand augering and machine-driven boreholes, to the ...

  8. Prospectivity mapping - Wikipedia

    en.wikipedia.org/wiki/Prospectivity_Mapping

    Prospectivity mapping. Prospectivity mapping, also known as mineral prospectivity mapping or mineral potential mapping, defines a process used to make better use of mineral exploration data. Geological and geophysical datasets, such as lithological, structural and topographical maps, aeromagnetic, gravity and radiometric imagery are the typical ...

  9. Geodynamics - Wikipedia

    en.wikipedia.org/wiki/Geodynamics

    v. t. e. Geodynamics is a subfield of geophysics dealing with dynamics of the Earth. It applies physics, chemistry and mathematics to the understanding of how mantle convection leads to plate tectonics and geologic phenomena such as seafloor spreading, mountain building, volcanoes, earthquakes, faulting. It also attempts to probe the internal ...
