Summary

The missing section grids describe geographic variations in erosion associated with unconformities in the 3D petroleum systems model. The grid values provide inputs for the model to restore layer thicknesses prior to erosion events and at the time of deposition. Each missing section grid here describes the depth of material that was eroded at 70, 50, 43, and 20 million years ago in the model. This is a child item of a larger data release titled "Data release for the 3D petroleum systems model of the Williston Basin, USA".

Purpose

Erosion events that occur around the timing of maximum burial can impact the maturation history of source rocks in the basin, thus the model requires assumptions about the erosion history to calibrate observed maturation indices with model results.
