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. The width and depth of the foreland basin is determined by the flexural rigidity of the underlyin… WebSteep angle of subduction leads to a narrow forearc basin. What is the source of the sediments in a forearc basin? Continental sediments and pyroclastic materials. If a back-arc basin is a region related to a subduction zone, how can such an extensional basin form near a boundary defined by compression?
WebThe Cenozoic history of the 14 km-thick Luzon Central Valley sequence illustrates the development of a forearc basin. Forearc basins are important both as major sediment traps and as sites of hydrocarbon accumulations. The Luzon basin is floored by oceanic crust on the seaward (western) side and older accreted terranes on the arc (eastern) side.
