Regional geophysics of western Utah and eastern Nevada, with emphasis on the Confusion Range

As part of a long term geologic and hydrologic study of several regional groundwater flow systems in western Utah and eastern Nevada, the U.S. Geological Survey was contracted by the Southern Nevada Water Authority to provide geophysical data. The primary object of these data was to enable construction of the geological framework of the flow...

Paleogeographic implications of Late Miocene lacustrine and nonmarine evaporite deposits in the Lake Mead region: Immediate precursors to the Colorado River

Thick late Miocene nonmarine evaporite (mainly halite and gypsum) and related lacustrine limestone deposits compose the upper basin fill in half grabens within the Lake Mead region of the Basin and Range Province directly west of the Colorado Plateau in southern Nevada and northwestern Arizona. Regional relations and geochronologic data indicate...

Populations of concern: Chapter 9

Climate change is already causing, and is expected to continue to cause, a range of health impacts that vary across different population groups in the United States. The vulnerability of any given group is a function of its sensitivity to climate change related health risks, its exposure to those risks, and its capacity for responding to or coping...

U.S. Geological Survey assessment of global potash production and resources—A significant advancement for global development and a sustainable future.

During the past 15 yr, the global requirement for fertilizers has grown considerably, mainly due to demand by a larger and wealthier world population for more and higher-quality food. The demand and price for potash as a primary fertilizer ingredient have increased in tandem, because of the necessity to increase the quantity and quality of food...

The Bonneville Flood—A veritable débâcle: Chapter 6

The Bonneville Flood was one of the largest floods on Earth. First discovered by G.K. Gilbert in the 1870s during his inspection of the outlet at Red Rock Pass, it was rediscovered in the 1950s by Harold Malde and coworkers, leading to mapping and assessment of spectacular flood features along Marsh Creek, Portneuf River, and Snake River for over...

Potash—A vital agricultural nutrient sourced from geologic deposits

This report summarizes the primary sources of potash in the United States. Potash is an essential nutrient that, along with phosphorus and nitrogen, is used as fertilizer for growing crops. Plants require sufficient potash to activate enzymes, which in turn catalyze chemical reactions important for water uptake and photosynthesis. When potassium...

Age, distribution and style of deformation in Alaska north of 60°N: Implications for assembly of Alaska

The structural architecture of Alaska is the product of a complex history of deformation along both the Cordilleran and Arctic margins of North America involving oceanic plates, subduction zones and strike-slip faults and with continental elements of Laurentia, Baltica, and Siberia. We use geological constraints to assign regions of deformation to...

Probing the volcanic-plutonic connection and the genesis of crystal-rich rhyolite in a deeply dissected supervolcano in the Nevada Great Basin: Source of the late Eocene Caetano Tuff

Late Cenozoic faulting and large-magnitude extension in the Great Basin of the western USA has created locally deep windows into the upper crust, permitting direct study of volcanic and plutonic rocks within individual calderas. The Caetano caldera in north–central Nevada, formed during the mid-Tertiary ignimbrite flare-up, offers one of the best...

Torbernite

Torbernite is a copper phosphate mineral that contains uranium, making it somewhat radioactive. Although it can be used as a uranium ore, it's more valued as a collectors mineral. It can be used as a good indicator of uranium deposits, however.

Sample provided by Carlin Green, USGS. Sample originated from Musonoi Mine, Democratic Republic of the Congo, and is 5.0cm in size.

Cannel Coal

Cannel coal is a type of bituminous coal, which is the second-highest rank of coal (just behind anthracite). This particular sample has a high carbon content with high pollen and spore content as well. Unlike most bituminous coal, Cannel coal can be carved into ornaments. This sample came from the Eastern Interior Coalfield in Kentucky.

Barre Granite

Granite is an igneous rock that we’ve used for building materials for thousands of years. It’s name comes from the Latin word “granum,” meaning “grain,” which refers to the grains of quartz and feldspar that define granite. This one is from the Barre formation in Vermont.

Hyperspectral Surveying: A Tool for Assessing the Mineral Potential of Alaska

Alaska is a major producer of base and precious metals and has a high potential for additional undiscovered mineral resources. However, discovery is hindered by Alaska’s vast size, remoteness and rugged terrain. New methods are needed to overcome these obstacles in order to evaluate Alaska’s geology and mineral resource potential.
