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 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]

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 Maracaibo Basin, also known as Lake Maracaibo natural region, Lake Maracaibo depression or Lake Maracaibo Lowlands, is a foreland basin and one of the eight natural regions of Venezuela, found in the northwestern corner of Venezuela in South America. Covering over 36,657 square km, it is a hydrocarbon-rich region that has produced over 30 ...
Forebulge associated with the formation of these basins is most commonly a result of convergent collision. [2] Foreland basins can occur in convergent subduction, but this is rare. [2] These basins are linked to fold-thrust belts, which are divided into three main types: collisional (peripheral), retroarc, and retreating collisional subduction. [4]
The West Congolian mobile belt became a foreland basin during the Pan-African orogeny and forms the granitoid Chaillu Massif spanning into the Republic of Congo through Gabon. The massif has a north-south foliation and two generations of granitoids.
