[Evolution of Sedimentary Basins/Onshore Oil and Gas Investigations--Santa Maria Province: Chapters Y and Z]

Description: From abstract: A complex Neogene history characterizes the offshore Santa Maria basin and the northwest margin of the western Transverse Ranges, California. This history includes the transition from subduction to a transtensional and then transpressional plate boundary, including about 900 of clockwise rotation of the western Transverse Ranges. This report uses seismic reflection data to document the geometry of structures that accommodated this deformation and offshore well data to date and correlate the sediments which were affected by the different tectonic episodes.

Stratigraphy of the Mississippian System, South-Central Colorado and North-Central New Mexico

Description: From abstract: In the Sawatch, Mosquito and Front Ranges of central Colorado and the Sangre de Cristo Mountains of south-central Colorado, Tournaisian beds of the Mississippian Leadville Limestone overlie rocks of Early Mississippian and Late Devonian age. In the Sangre de Cristo Mountains in north-central New Mexico, the oldest beds are the Tournaisian (zone 9) Espiritu Santo Formation. In west-central New Mexico, in the Magdalena, Lemitar, and Ladron Mountains, the Kelly Limestone of Tournaisian and Visean age rests unconformably on Proterozoic metamorphic and igneous rocks. This report examines the stratigraphy of this area.

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

Description: 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 the Gold Bond area immediately east of the study area.

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

Description: 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.

Mineral Resources of the Wabayuma Peak Wilderness Study Area, Mohave County, Arizona

Description: From abstract: The Wabayuma Peak Wilderness Study Area (AZ-020-037/043), for which a mineral survey was requested by the U.S. Bureau of Land Management, encompasses 40,118 acres in northwestern Arizona. Fieldwork was carried out in 1986-88 by the U.S. Bureau of Mines and the U.S. Geological Survey to appraise the identified (known) resources and assess the mineral resource potential (undiscovered) of the wilderness study area. Within the Wabayuma Peak Wilderness Study Area are 14 private parcels of land totaling 1,315 acres. The Wabayuma Peak Wilderness Study Area, including the 14 private parcels of land, is herein referred to as the "wilderness study area" or the "study area." The Boriana, Antler, and Copper World mines lie near the east boundary of the study area. The Boriana mine was a major tungsten-producing mine of the United States during World War II. The Antler and Copper World mines produced relatively small amounts of copper and zinc prior to 1970.

Mineral Resources of the Warm Springs Wilderness Study Area, Mohave County, Arizona

Description: From abstract: At the request of the U.S. Bureau of Land Management, approximately 113,500 acres of the Warm Springs Wilderness Study Area (AZ-020-028/029) were evaluated for mineral resources and mineral resource potential. In this report, the area studied is referred to as the "wilderness study area" or "study area"; any reference to the Warm Springs Wilderness Study Area refers only to that part of the wilderness study area for which a mineral survey was requested. This study area is located in west-central Arizona. The U.S. Geological Survey and the U.S. Bureau of Mines conducted geological, geochemical, and geophysical surveys to appraise the identified mineral resources (known) and assess the mineral resource potential (undiscovered) of the study area. Fieldwork for this report was carried out largely in 1986-1989.

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

Description: 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 Paria-Hackberry Wilderness Study Area, Kane County, Utah

Description: From abstract: The Paria-Hackberry Wilderness Study Area, in central Kane County, southern Utah, is a region of generally flat-lying, gently folded sedimentary rocks, bounded on the east by the east-dipping limb of the East Kaibab monocline and cut by sheer-walled, narrow canyons. The area selected for study by the U.S. Bureau of Land Management totaled 94,642 acres (148 square miles); because of uncertainty as to final boundaries, the U.S. Geological Survey studied an additional contiguous 41,180 acres (64 square miles).
