| Description |
The 1986 exploration program focused on detailed geological and geophysical field work in outlying areas of hydrocarbon leases east of Mt. Bartles. Field work was also completed in the Whitmore Canyon area. The field program extended from June 16 through September 19. During this time geological and geophysical data was gathered from eighteen new measured sections and four old measured sections over a total vertical distance encompassing 15,212 feet. The objectives of the exploration program were: 1. to evaluate the tar sand potential in outlying areas of hydrocarbon leases by numerous measured sections and surface samples from major tar zones; 2. to obtain surface gamma ray data from a portable spectrometer to aid in correlation of major tar zones; 3. to determine the existence of the Mahogany ledge or other marker beds that could be used to correlate the Sunnyside Tar Sands with the regional stratigraphy of the Uinta Basin; 4. to help coordinate removal of 1000 tons of tar sand from Zone 43 in the quarry of the Asphalt Mine for shipment to Chicago; 5. to complete an initial reconnaissance of the proposed conveyor belt route from Grassy Trail Reservoir to the mouth of B Canyon and the proposed plant site in Clark Valley. The scope of this report focuses on the results of the 1986 field work and serves as an addendum to previous exploration reports. Key photographs are used to highlight aspects of the Sunnyside Tar Sands deposit and are included in Volume I. A large separate mosaic of five aerial obliques provides an excellent view of the Sunnyside Tar Sands area. As in previous reports columnar sections of strip logs were compiled from the field work. The three geology maps are included in Volume II. The eighteen new strip logs are in Volume III. Field work established major and minor environments of deposition and coupled with the surface gamma ray logs were used to correlate and determine the numbered tar zones. These numbered tar zones (10, 11, 21, 23, 25, 26, 31, 22, 35, 36, 99, 37, 38, 41, 42, 43 and 45) zppear on the strip logs and in Tables 10-12 that contain tar zone data from Measured Sections 1- 44. The use of these numbered tar zones has led to a simpler and more comprehension view of the Sunnyside delta complex. |
