02.3_Forearc – An Introduction to Geology

Forearc is a plate tectonic term referring to a region between an oceanic trench, also known as a subduction zone, and the associated volcanic arc. Forearc regions are present along a convergent margins and eponymously form 'in front of' the volcanic arcs that are characteristic of convergent plate margins. A … See more During subduction, an oceanic plate is thrust below another tectonic plate, which may be oceanic or continental. Water and other volatiles in the down-going plate cause flux melting in the upper mantle, creating magma … See more The forearc region includes any forearc basin, outer-arc high, accretionary prism and the trench itself. The accretionary prism is located at the slope of the trench break where there is significantly decreased slope angle. Between the break and the magmatic … See more One good example is the Mariana forearc, where scientists have done extensive research. In this setting there is an erosive margin and forearc slope which consists of 2 km high and 30 km diameter serpentine- mud volcanoes. The erosive properties of these volcanoes … See more There are two models which characterize a forearc basin formation and deformation and are dependent on sediment deposition and subsidence … See more The intense interaction between the overriding and underthrusting plates in the forearc regions have shown to evolve strong coupling … See more • Back-arc region See more WebJun 21, 2024 · 1. Introduction. Forearc basin is one of the major elements of plate convergent margins (e.g., [1, 2]).The formation is considered to be closely associated with accretion or erosion at frontal and basal parts of accretionary wedge (e.g., [3–5]).Especially, the seaward margin of the basin is directly affected by uplift and subsidence of the outer … WebAug 28, 2013 · 2.1.
