There are two models which characterize a forearc basin formation and deformation and are dependent on sediment deposition and subsidence (see figure). The first model is associated with a forearc basin formed with little to no sediment supply. Conversely, the second model is associated with sediment supply. … See more 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 … 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 … 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 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 that rises and penetrates the overriding plate, … 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 WebMay 1, 2011 · A large sedimentary forearc basin developed in Cenozoic times between the present-day Coastal Cordillera and the Western Cordillera of the Central Andes, called …
WebDec 1, 2024 · The transects show that the forearc basin sediments are onlapping onto the frontal prism. In MCS-041-7T (Fig. 11), the distinct growth strata overserved to be developing on the western flank of the frontal wedge, indicate the continued uplift in the wedge. Abundant sediment supply is also probably sourced from the uplift in the frontal … WebMar 27, 2024 · Dimension of forearc basin depends on the arc-trench gap. Continental margin or oceanic crust may form the base of forearc basin. Concerning its capacity to accumulate sediments, rate of subsidence of forearc basin is controlled by sediment loading.
