| Description |
The 1984 Sunnyside exploration program consisted of: (1) diamond drilling of fifteen drill holes, (2) logging of all core and (3) additional geological mapping in the north area to better define the limits of the tar sands associated with the Sunnyside delta complex. Both regional and detailed geological studies were completed in order to comprehend the geometry of the Sunnyside Tar Sands deposit. As in previous programs columnar sections or strip logs were compiled from the exploration results. The new twenty-four strip logs are included in Volume III and represent nine measured sections completed in the north area, ten deep drill holes completed in or near the north area and five shallow pilot mine drill holes completed near the Arco water tank. During the compilation of these twenty-four columnar sections detailed stratigraphic analysis established major and minor environments of deposition that defined various aspects of the Sunnyside delta complex. The numbered tar zones in all drill holes and measured sections were correlated throughout the delta complex. These numbered tar zones appear on the new strip logs as well as the updated geologic maps and cross sections. The use of these numbered tar zones (i.e. Zones 11, 21, 23, 25, 26, 31, 33, 35, 36, 99, 37, 38, 41, 42, 43, and 45) throughout the delta complex has led to a better comprehension of the Sunnyside Tar Sand deposit. The scope of this report represents a compilation of the geological studies of the delta complex at the Sunnyside Tar Sands Project completed during 1980-1984. |
