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 Himalayan foreland basin has been divided on the basis of modern drainage divides, [2] and subsurface topography. [7] [8] Subdivisions based on drainage divides are most commonly used, with the Indus Basin reflecting the drainage area of the Indus River, and the Ganga Basin representing the drainage area of the Ganges River.
The Nama Basin is a peripheral foreland basin, and the Nama Group was deposited in two early basins, the Zaris and Witputs, to the north, while the South African Vanrhynsdorp Group was deposited in the southern third. [1] The Nama Group is made of fluvial and shallow-water marine sediments, both siliciclastic and carbonate. [2]

The Magallanes Basin is a foreland basin located in southern Patagonia. The basin covers a surface of about 170.000–200.000 km 2 and has a NNW-SSE oriented shape. [9] [10] The basin evolved from being an extensional back-arc basin in the Mesozoic to being a compressional foreland basin in the Cenozoic. [11]
Peripheral foreland basins - where the topographic load of a large mountain belt being formed and thrust onto a plate, usually as a result of orogenisis due to continental collision, causes continental lithosphere to bend downward along the mountain front. Retroarc foreland basins - which form behind (landward from) an active volcanic arc ...
The Acadian foreland basin is a retroarc. Foreland basins are a product of tectonic deformational loading, or crustal thickening along the orogen, a consequence of overthrusting and folding. The Acadian foreland basin is categorized as a retroarc foreland basin, which occurs on the overriding continental lithosphere, adjacent to a foreland fold ...
The Appalachian Basin is a foreland basin containing Paleozoic sedimentary rocks of early Cambrian through early Permian age. From north to south, the Appalachian Basin province crosses New York , Pennsylvania , eastern Ohio , West Virginia , western Maryland , eastern Kentucky , western Virginia , eastern Tennessee , northwestern Georgia , and ...
