  2. Joint (geology) - Wikipedia

    en.wikipedia.org/wiki/Joint_(geology)

    Although joints can occur singly, they most frequently appear as joint sets and systems. A joint set is a family of parallel, evenly spaced joints that can be identified through mapping and analysis of their orientations, spacing, and physical properties. A joint system consists of two or more intersecting joint sets. [1] [2] [3]

  3. Geology of Germany - Wikipedia

    en.wikipedia.org/wiki/Geology_of_Germany

    The surface geology of Germany has evolved to its current configuration due to regional differences in the action and appearance of external and internal forces during the last c. 20 million years. Germany can be divided into three physiographic regions: the Central European Depression, the Central European Blocks and the Alps.

  4. Structural geology - Wikipedia

    en.wikipedia.org/wiki/Structural_geology

    Structural geology is the study of the three-dimensional distribution of rock units with respect to their deformational histories. The primary goal of structural geology is to use measurements of present-day rock geometries to uncover information about the history of deformation ( strain ) in the rocks, and ultimately, to understand the stress ...

    en.wikipedia.org/wiki/Columnar_jointing

    Columnar jointing in Giant's Causeway in Northern Ireland Columnar jointing in the Alcantara Gorge, Sicily. Columnar jointing is a geological structure where sets of intersecting closely spaced fractures, referred to as joints, result in the formation of a regular array of polygonal prisms (basalt prisms), or columns.

  6. 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 use of geophysical techniques and remote sensing ...

    Classic geological compass (Brunton), sideview Classic geological compass (Brunton), topview. There are a number of different specialized magnetic compasses used by geologists to measure orientation of geological structures, as they map in the field, to analyze and document the geometry of bedding planes, joints, and/or metamorphic foliations and lineations.

  8. Geometallurgy - Wikipedia

    en.wikipedia.org/wiki/Geometallurgy

    There are four important components or steps to developing a geometallurgical program,: [1] the geologically informed selection of a number of ore samples; laboratory-scale test work to determine the ore's response to mineral processing unit operations; the distribution of these parameters throughout the orebody using an accepted geostatistical ...

    4) By using programs, such as Coltop 3D, the structural geometry of the joint/slope planes can be calculated automatically. [ 8 ] 5) The rock planes are determined by color-coding or statistical method for evaluating whether the points are grouped to form a single or different planes.
