pybacktrack.estimate_rift_beta

pybacktrack.estimate_rift_beta(present_day_subsidence, present_day_crustal_thickness, rift_end_time)

Estimate the stretching factor (beta).

Parameters:

• present_day_subsidence (float) – The (sediment-free) subsidence at present day (in metres).

• present_day_crustal_thickness (float) – The crustal thickness at present day (in metres).

• rift_end_time (float) – The time that rifting ended (in My).

Returns:

• beta (float) – The estimated stretching factor.

• residual (float) – The inaccuracy between present day subsidence and subsidence calculated using the estimated stretching factor (beta).

Notes

Stretching factor (beta) is calculated by minimizing difference between actual subsidence and subsidence calculated from beta (both at present day).
