A structural basin is a large-scale structural formation of rock strata formed by tectonic warping of previously flat lying strata. Structural basins are synonymous in some ways with geological depressions. Structural basins are distinct from a sedimentary basin which is a time-dependent aggregation of rocks which filled up a depression or accumulated within an area.

The term sedimentary basin is used to refer to any geographical feature exhibiting subsidence and consequent infilling by sedimentation. ...
Structural basins are the inverse of a dome: a symmetrically-dipping syncline that appears on a geologic map as roughly circular or elliptical, with concentric layers. Because the strata dip toward the center, the exposed strata in a basin grow progressively younger from outside-in, with the youngest rocks in the center. Like domes, basins are often large in areal extent, a good example being the Michigan Basin. In geology, a dome is a deformational feature consisting of symmetrically-dipping anticlines; their general outline on a geologic map is circular or oval. ... Strike and dip refer to the orientation or attitude of a geologic feature. ... Road Cut near Ft. ... Goldenville Strata exposed at a quarry in Bedford, Canada. ...
