  2. Type locality (geology) - Wikipedia

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

    Type locality, also called type area, is the locality where a particular rock type, stratigraphic unit or mineral species is first identified. [1] If the stratigraphic unit in a locality is layered, it is called a stratotype, whereas the standard of reference for unlayered rocks is the type locality.

  3. Tectonic uplift - Wikipedia

    en.wikipedia.org/wiki/Tectonic_uplift

    Tectonic uplift is the geologic uplift of Earth's surface that is attributed to plate tectonics. While isostatic response is important, an increase in the mean elevation of a region can only occur in response to tectonic processes of crustal thickening (such as mountain building events), changes in the density distribution of the crust and ...

  4. Tectonics - Wikipedia

    en.wikipedia.org/wiki/Tectonics

    Extensional tectonics is associated with the stretching and thinning of the crust or the lithosphere.This type of tectonics is found at divergent plate boundaries, in continental rifts, during and after a period of continental collision caused by the lateral spreading of the thickened crust formed, at releasing bends in strike-slip faults, in back-arc basins, and on the continental end of ...

  5. The Topeka School - Wikipedia

    en.wikipedia.org/wiki/The_Topeka_School

    As in Lerner's previous novels, the narrative contains autobiographical elements. Like the protagonist, Adam Gordon, Lerner grew up in Topeka and won a national debate championship in high school, and like Adam's mother Jane in the novel, Lerner's mother, Harriet Lerner, is a psychologist who has published best-selling books aimed at a non-academic audience.

  6. Shield (geology) - Wikipedia

    en.wikipedia.org/wiki/Shield_(Geology)

    A shield is a large area of exposed Precambrian crystalline igneous and high-grade metamorphic rocks that form tectonically stable areas. [1] These rocks are older than 570 million years and sometimes date back to around 2 to 3.5 billion years.

  7. Detachment fault - Wikipedia

    en.wikipedia.org/wiki/Detachment_fault

    They cannot be structurally restored, as slip on the fault exceeds the thickness of oceanic crust (~30 km compared to ~6 km, for example). [ 7 ] While occurring at relatively amagmatic spreading centres, the footwalls of these detachment faults are much more influenced by magmatism than in continental settings.

  8. Window (geology) - Wikipedia

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

    A tectonic window, or fenster (lit. "window" in German), is a geologic structure formed by erosion or normal faulting on a thrust system. In such a system the rock mass (hanging wall block) that has been transported by movement along the thrust is called a nappe.

  9. Andesite line - Wikipedia

    en.wikipedia.org/wiki/Andesite_line

    The andesite line is the most significant regional geologic distinction in the Pacific Ocean basin. It separates the mafic basaltic volcanic rocks of the Central Pacific Basin from the partially submerged continental areas of more felsic andesitic volcanic rock on its margins.
