  2. Forearc - Wikipedia

    en.wikipedia.org/wiki/Forearc

    Over geological time there is constant recycling of the forearc deposits due to erosion, deformation and sedimentary subduction. The constant circulation of material in the forearc region (accretionary prism, forearc basin and trench) generates a mixture of igneous, metamorphic and sedimentary sequences.

  3. North Luzon Trough - Wikipedia

    en.wikipedia.org/wiki/North_Luzon_Trough

    The North Luzon Trough is a major geological feature located off the northern coast of Luzon Island between the Manila Trench and the Vigan-Agao Fault in the Philippines. [1] It is a well-developed forearc basin formed in front of the Luzon Volcanic Arc , an island arc system. [ 2 ]

  4. Osorno–Llanquihue Basin - Wikipedia

    en.wikipedia.org/wiki/Osorno–Llanquihue_Basin

    The Osorno–Llanquihue Basin (Spanish: Cuenca Osorno-Llanquihue) is a sedimentary basin located in south-central Chile in the forearc region of the Andes. From north to south the basin spans and area from Catamutún to Reloncaví Sound (40–42° S). [1] The deepest part of the basin lie to the east. [2]

  5. Arauco Basin - Wikipedia

    en.wikipedia.org/wiki/Arauco_Basin

    In the context of plate tectonics it is classified as a forearc basin. The basin has an approximate area of 8,000 square kilometres (3,100 sq mi) and at its deeper parts the surface of its sedimentary fill reaches 200 metres (660 ft) below sea-level. [1] The basin is interpreted as being part of an uplifted part of the continental shelf. [2]

  6. Foreland basin - Wikipedia

    en.wikipedia.org/wiki/Foreland_basin

    A foreland basin is a structural basin that develops adjacent and parallel to a mountain belt. Foreland basins form because the immense mass created by crustal thickening associated with the evolution of a mountain belt causes the lithosphere to bend, by a process known as lithospheric flexure.

  7. Oregon Coast Range - Wikipedia

    en.wikipedia.org/wiki/Oregon_Coast_Range

    volcanic and forearc basin The Oregon Coast Range , often called simply the Coast Range and sometimes the Pacific Coast Range , is a mountain range , in the Pacific Coast Ranges physiographic region , in the U.S. state of Oregon along the Pacific Ocean .

  8. Cook Inlet Basin - Wikipedia

    en.wikipedia.org/wiki/Cook_Inlet_Basin

    The Cook Inlet Basin is a northeast-trending collisional forearc basin that stretches from the Gulf of Alaska into South central Alaska, just east of the Matanuska Valley. It is located in the arc-trench gap between the Alaska-Aleutian Range batholith and contains roughly 80,000 cubic miles of sedimentary rocks . [ 1 ]

  9. Accretionary wedge - Wikipedia

    en.wikipedia.org/wiki/Accretionary_wedge

    Piggy-back basins, which are small basins located in surface depression on the accretionary prism. Material exposed in the forearc ridge may include fragments of oceanic crust or high pressure metamorphic rocks thrust from deeper in the subduction zone.
