Geologic summary report of the 1990 exploration program, Sunnyside Tar Sands project, Carbon County, Utah--volume 1

This 1990 report is a supplement to the extensive 1989 report. This 1990 report concentrates on results of the following four categories: (1) regional geology and engineering geology needed to investigate the feasibility of conveyor routes that will bring the tar sand ore down from the Roan Cliffs through the Book Cliffs to Clark Valley (see Regional Geology Map and Cross Section in Volume II as well as Figures 2 and 25 in Volume I); (2) completion of three short measured sections in the "hot spot" of the. South Area to further delineate the extent and grade of Zones 31, 32, 33 and 35 (see strip logs in Volume II); (3) composite photos prepared to identify the outcrops of numbered tar zones along the Roan Cliffs (see Photos 2, 3,4 and 5 in Volume I); (4) presentation and interpretation of an isopach, or thickness, map for each of the fifteen numbered tar zones (see Isopach Maps in Volume II). The first two categories were accomplished during a one month summer field program from mid-June to mid-July 1990. The last two categories were completed during the ensuing months of office work. The detail in the composite photos is the result of eleven years of exploration work.
