  2. Ore genesis - Wikipedia

    en.wikipedia.org/wiki/Ore_genesis

    Plate tectonics is the underlying mechanism for generating gold deposits. The majority of primary gold deposits fall into two main categories: lode gold deposits or intrusion -related deposits. Lode gold deposits , also referred to as orogenic gold are generally high-grade, thin, vein and fault hosted.

  3. Iron oxide copper gold ore deposits - Wikipedia

    en.wikipedia.org/wiki/Iron_oxide_copper_gold_ore...

    Iron oxide copper-gold deposits are also often associated with other valuable trace elements such as uranium, bismuth and rare-earth metals, although these accessories are typically subordinate to copper and gold in economic terms. Some examples include the Olympic Dam, South Australia, and Candelaria, Chile deposits.

  4. Earth's crustal evolution - Wikipedia

    en.wikipedia.org/wiki/Earth's_crustal_evolution

    Mars, Venus, Mercury and other planetary bodies have relatively quasi-uniform crusts unlike that of the Earth which contains both oceanic and continental plates. [1] This unique property reflects the complex series of crustal processes that have taken place throughout the planet's history, including the ongoing process of plate tectonics.

  5. Vine–Matthews–Morley hypothesis - Wikipedia

    en.wikipedia.org/wiki/Vine–Matthews–Morley...

    The Vine–Matthews–Morley hypothesis, also known as the Morley–Vine–Matthews hypothesis, was the first key scientific test of the seafloor spreading theory of continental drift and plate tectonics. Its key impact was that it allowed the rates of plate motions at mid-ocean ridges to be computed.

    English: How Earth's tectonic plates and lands may have been positioned and moved in the past: an animated video of a full-plate tectonic model extended one billion years into the past. It is a result of the 2020 study "Extending full-plate tectonic models into deep time".

  7. Triple junction - Wikipedia

    en.wikipedia.org/wiki/Triple_junction

    The Azores triple junction is a geologic triple junction where the boundaries of three tectonic plates intersect: the North American plate, the Eurasian plate and the African plate, R-R-R. [9] The Boso triple junction offshore of Japan is a T-T-T triple junction between the Okhotsk microplate, Pacific plate and Philippine Sea plate.

  9. List of tectonic plates - Wikipedia

    en.wikipedia.org/wiki/List_of_tectonic_plates

    These plates are often grouped with an adjacent principal plate on a tectonic plate world map. For purposes of this list, a microplate is any plate with an area less than 1 million km 2 . Some models identify more minor plates within current orogens (events that lead to a large structural deformation of Earth's lithosphere ) like the Apulian ...
