sedimentary basins
Rift basins - Thermal Implication:

The surface of the continent is taken to be at or below sea level, and continental crust is assumed to be preserved. The sign of the initial subsidence Si depends on the initial crustal thickness hc and is independent on the stretching factor β. Initial subsidence will occur (i.e. Si = positive) if hc > 18 km. If hc < 18 km, initial uplift will occur (under water, though). The crustal thickness must be at least 27.6 km for the crustal surface to be at sea level, or above. Hence it is impossible that initial subaerial uplift would occur.

Another refinement of McKenzie's (1978) original model was presented in a paper by Jarvis and McKenzie (1980), in which they modified the original model to account for the impact of time-dependent stretching on subsidence (stretching is no longer instantaneous but occurs over a time span). When stretching occurs over a period comparable to the diffusion time scale some of the heat diffuses away before stretching is completed. The resultant thermal anomaly and subsequent contraction is thus reduced.
Their analysis showed that if the time period of extension by a factor β is less than 60/β2 m.y., the resulting subsidence differs little from an instantaneous stretching model for b <2. For β >2, the time period of stretching must be shorter than 60(1 – 1/β)2.
