Knowra Foreland basin Foreland basin A sedimentary basin that forms beside a mountain belt when the weight of the growing orogen bends adjacent lithosphere downward. It commonly fills with sediment eroded from the mountains.
Lithospheric flexure : The bending of the lithosphere under loads such as mountain belts, volcanoes, or ice sheets. The orogen's load depresses the neighboring plate and creates space for basin sediments.
Sedimentary basin : A region of long-term subsidence where sediment accumulates and is preserved. Foreland basins are a tectonically defined kind of sedimentary basin.
Himalayan foreland basin : The sedimentary basin south of the Himalaya, extending across parts of Pakistan, India, Nepal, and Bangladesh. Its deposits record loading by the Himalaya and sediment delivery from the growing range.
Back-arc basin : A basin that forms behind a volcanic arc, commonly through extension above a subducting plate. It forms behind an arc through tectonic extension, rather than beside an orogen through flexural loading.
Sequence stratigraphy : The study of genetically related sedimentary strata bounded by surfaces that reflect changes in accommodation and sediment supply. Its framework helps interpret shifting shorelines and sediment packages in basin fill.
Isostasy : The gravitational balance in which Earth's lithosphere floats at elevations set by its thickness and density. Isostatic compensation helps explain how crustal loads and subsidence interact.
Orogeny : The processes by which tectonic forces build a mountain belt. An orogeny creates the mountain load beside which a foreland basin develops.
Ganges Basin : A large alluvial basin in South Asia drained chiefly by the Ganges and its tributaries. Its northern part includes the foreland basin formed beside the Himalaya.
Rift basin : A sedimentary basin formed as continental lithosphere stretches, thins, and subsides. Its subsidence comes from extension and thinning instead of mountain-belt loading.
Provenance (geology) : The origin and transport history of sediment, inferred from its minerals, grains, and geochemistry. Provenance data can link basin deposits to rocks exposed in the adjacent orogen.
