sedimentary basin
Let an agent explain sedimentary basins, relay formation mechanisms, types, resources and analysis methods from geology sources, describe the named basin types, and distinguish sedimentary basins from drainage basins, ocean basins in the geographic sense, structural basins as folds and depressions without sediment fill.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain sedimentary basins, relay formation mechanisms, types, resources and analysis methods from geology sources, describe the named basin types, and distinguish sedimentary basins from drainage basins, ocean basins in the geographic sense, structural basins as folds and depressions without sediment fill.
A region of long-term subsidence where sediments accumulate to great thickness, formed by tectonic processes such as rifting, which creates rift and passive margin basins, lithospheric flexure under mountain belts, which creates foreland basins, and strike-slip movement, preserving records of past environments and hosting most of the world s petroleum and gas, coal basins, including brown coal or lignite basins and coal-bearing areas, and groundwater aquifers; basin analysis combines stratigraphy, geophysics and subsidence modelling.
What it is for: Understanding Earth history and resources.
It can be explain formation mechanisms; relay basin types; describe resource basins; distinguish related uses of basin.
Distinguishing features
Subsidence
Thick sediment fill
Resource host
Environmental archive
What it looks like
Not visible as a whole at the surface; mapped as thick sedimentary layers in seismic sections and geological maps.
Physical character
sediment thickness: up to more than 10 km - in deep basins
main mechanisms: rifting, flexure, strike-slip, thermal subsidence list
registry parent: basin note
How it is recognised
Region of subsidence with thick sediment fill
Foreland basin, coal basin, petroleum and gas basin, brown coal basin, coal-bearing area
Drainage basins are river catchments; ocean basins are seafloor regions; structural basins are downfolds; depressions may lack thick fill
