Sub-Cretaceous Unconformity Elevation, West-Central Alberta (gridded data, ASCII format)

Author(s) Peterson, J.T. Date 2017-04-07

The sub-Cretaceous unconformity is a major component of the three-dimensional geological model of Alberta. This dataset is a two-and-a-half dimensional (2.5D) grid surface of the sub-Cretaceous unconformity elevation in west-central Alberta. To create this grid, stratigraphic picks of the sub-Cretaceous unconformity were geostatistically analyzed and interpolated to model the unconformity surface elevation. This grid has been clipped by the study area boundary.

The study area covers NTS map sheets 83G, 83J, 83K, and parts of 83F. The southwestern limit of the study area is defined by the approximate limit of the main Cordilleran deformation.
