BasinmodlR: Burial and Thermal History Modelling of Sedimentary Basins
Simulates the burial, compaction and thermal history of a
sedimentary basin in one dimension, for geologists and stratigraphers.
A basin is described by one row per stratigraphic unit and one row per
erosion event, from which deposition phases, hiatuses, layer stacks,
maximum-burial windows and grain (solid) thicknesses are derived.
Compaction follows an exponential porosity-depth law and is irreversible,
so uplifted layers keep the porosity acquired at their deepest burial.
Temperatures follow the steady-state conductive geotherm of a layered
column with radiogenic heat production. The methods follow the textbook
treatment of Allen and Allen (2013, ISBN:978-0-470-67377-5). Functions
are included to draw a composite figure of burial, temperature and
hydrocarbon generation windows and a petroleum system event chart.
