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 for the Peace River and Slave Lake regions of Alberta. The study area boundary covers NTS map sheets 83N, 83O, 84C, and 84B.
To create this grid, stratigraphic picks of the sub-Cretaceous unconformity were geostatistically analyzed and interpolated to model the unconformity surface elevation. The grid was then clipped by the study area boundary.
