structural basin
Let an agent explain structural basins, relay formation mechanisms, classification and resources from geology sources, describe the named basin types and flag related concepts, and distinguish structural basins from drainage basins, ocean basins, glacial basins and structural domes.
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 structural basins, relay formation mechanisms, classification and resources from geology sources, describe the named basin types and flag related concepts, and distinguish structural basins from drainage basins, ocean basins, glacial basins and structural domes.
A large-scale geological depression in which rock strata dip toward a central point, forming a bowl-shaped structure often filled with thick sedimentary sequences, such as the Michigan Basin and Paris Basin, formed by processes including crustal subsidence, rifting, strike-slip motion creating pull-apart basins, and extension behind volcanic arcs forming back-arc basins; structural basins host petroleum, coal, groundwater and geothermal resources. The registry aliases oceanic basin, a bathymetric feature, and Zungenbecken, a glacial tongue basin, are related but distinct concepts.
What it is for: Not applicable; a geological structure.
It can be explain formation mechanisms; relay classification; describe named basin types; distinguish related basins.
Distinguishing features
Inward dipping strata
Thick sediments
Tectonic origin
Resource significance
What it looks like
Seen on geological maps as concentric outcrop rings with the youngest rocks in the centre.
Physical character
Michigan Basin sediment thickness: up to about 5 km - approximate
outcrop pattern: youngest rocks at centre note
registry parents: geologic province, basin note
How it is recognised
Bowl-shaped depression of dipping rock strata
Oceanic basin, Zungenbecken, pull-apart basin, back-arc basin
Drainage basins are hydrological; ocean basins are seafloor features; glacial tongue basins are erosional; domes have strata dipping outward
