Geologic summary report of the 1989 exploration program, Sunnyside tar sands project, Carbon County, Utah

This report includes the 1989 data and represents a summary of previous exploration reports. Eight photographs included in Volume I are used to highlight aspects of the Sunnyside. Tar Sands project. Volume II contains five maps and five cross sections. Volume III contains twenty-six strip logs. Both field and drill core data were used in conjunction with gamma ray well logs to correlate and determine numbered tar zones. The use of numbered tar zones has established continuity between the field data and drill hole data throughout the entire Sunnyside Tar Sands area. The numbered tar zones and bitumen content of each drill hole and measured section completed since 1980 appear in Tables 1, 2 and 3. Table 4 is a compilation of the lithology within the western segment of the flexure. It is based on forty-nine drill holes and shows important differences exist between the north, central and south areas. Environments of deposition were determined from both core logging and field work; have been helpful in the lithologic correlations; and useful to comprehend the Sunnyside delta complex. Table 5 is a summary of the various rocks that exist within the tar sand area and includes a listing of associated bitumen content, rock type, common color, fossils, distinguighing characteristics and environments of deposition. The 1989 field program focused on logging 11,098 feet of core from twenty-two drill holes completed by Mono Power in 1982 and 1983. Two new measured sections were also completed. Five marker units exist within the area and include the Wavy Bedded Tuff, Mahogany oil shale, R-5 oil shale, Blue Marker, and carbonate interval. The 1989 field season extended from June 6 through September 1 and included 64.5 working days. A breakdown of these working days includes 1 day of organization; 39 days for logging core (38 days in Price and 1 day in Naperville); 11 days for field mapping and measured sections; 13 days for travel and 0.5 day for a project meeting in Naperville. The weather was abnormally dry. Water levels in creeks and springs were at their lowest levels in the past ten years.
