Mineral Resources of the Sleeping Giant Wilderness Study Area, Lewis and Clark County, Montana (open access)

Mineral Resources of the Sleeping Giant Wilderness Study Area, Lewis and Clark County, Montana

From abstract: A mineral resource survey was conducted in 1987 by the U.S. Geological Survey and the U.S. Bureau of Mines to evaluate mineral resources (known) and mineral resource potential (undiscovered) of the Sleeping Giant Wilderness Study Area (MT-075-111) in Lewis and Clark County, Montana. The only economic resource in the study area is an inferred 1.35-million-ton reserve of decorative stone (slate); a small gold placer resource is subeconomic. A high resource potential for decorative slate exists directly adjacent to the area of identified slate resource and in the northeastern part of the study area. The rest of the study area has a low potential for decorative slate. The westernmost part of the study area has a moderate resource potential for copper and associated silver in strata-bound deposits in green beds and limestone; potential is low in the rest of the study area.

Mineral Resources of the Deep Creek Mountains Wilderness Study Area, Juab and Tooele Counties, Utah (open access)

Mineral Resources of the Deep Creek Mountains Wilderness Study Area, Juab and Tooele Counties, Utah

From abstract: The Deep Creek Mountains Wilderness Study Area (UT-020-060/UT-050-020) includes most of the Deep Creek Range of west-central Utah. The area is near the Utah-Nevada State line, south of Wendover, Utah, and northwest of Delta, Utah. Eleven areas of mineralized rock in and near the study area were evaluated by the U.S. Bureau of Mines. Four of these areas contain identified resources: (1) an indicated resource of 5,000 short tons of 16.5 ounces silver per short ton, 4.1 percent lead, 4.6 percent zinc, and 0.25 percent copper, at the Willow Springs area, which is almost surrounded by the study area in the northeast corner although it is not part of the study area; (2) an indicated gold resource of 774,000 short tons of 0.4 ounces per short ton and an inferred gold resource of 5.7 million short tons of 0.4 ounces per short ton in the Goshute Canyon area immediately east of the study area; (3) an indicated gold resource of 75,000 short tons of 0.22 ounces per short ton in the Queen of Sheba mine just west of the study area; and (4) an inferred gold resource of 3,800 short tons of 0.26 ounces per short ton in …

Mineral Resources of the Cockscomb and Wahweap Wilderness Study Areas, Kane County, Utah (open access)

Mineral Resources of the Cockscomb and Wahweap Wilderness Study Areas, Kane County, Utah

Summary: At the request of the U.S. Bureau of Land Management, two wilderness study areas in southern Utah (fig. 1) were studied in order to appraise their identified mineral resources and assess their potential mineral resources. The areas studied are the Cockscomb (UT-040-275) Wilderness Study Area, 5,100 acres (8 square miles), and the Wahweap (UT-040-248) Wilderness Study Area, 70,380 acres (110 square miles), both in Kane County, Utah. In this report the areas studied are called "wilderness study areas," simply "study areas," or "Cockscomb area" or "Wahweap area," as appropriate. The Cockscomb area (fig. 1) lies along the steeply east-dipping East Kaibab monocline, and the Wahweap area, farther to the east, consists of flat-lying but gently folded rocks. These areas adjoin the Paria-Hackberry Wilderness Study Area (UT-040-247) to the west.

Fluvial Architecture of the Lower Cretaceous Lakota Formation, Southwestern Flank of the Black Hills Uplift, South Dakota (open access)

Fluvial Architecture of the Lower Cretaceous Lakota Formation, Southwestern Flank of the Black Hills Uplift, South Dakota

From introduction This report describes large-scale depositional units referred to as architectural elements, interpreted from outcrops of three distinct fluvial sandstone units of the Lakota Formation in the southwestern Black Hills area of Custer and Fall River Counties, South Dakota. These fluvial deposits formed near the end of an episode of continental deposition that began when the Jurassic Sundance sea regressed from the region and ended when the Early Cretaceous Skull Creek sea encroached from the north in Albian time.
