Our objectives are to: 1) collect and assimilate digital geospatial data in a standardized format for minerals-related research and assessments, 2) develop and improve analytical procedures for using geospatial data in minerals products, 3) provide support for timely, quality, and reproducible mineral assessments, 4) provide easy access to the data, and 5) report results of our work in a digital format that can be incorporated into GIS systems.

Sediment-hosted gold deposits of the world: Database and grade and tonnage models Sediment-hosted gold deposits of the world: Database and grade and tonnage models
All sediment-hosted gold deposits (as a single population) share one characteristic—they all have disseminated micron-sized invisible gold in sedimentary rocks. Sediment-hosted gold deposits are recognized in the Great Basin province of the western United States and in China along with a few recognized deposits in Indonesia, Iran, and Malaysia. Three new grade and tonnage models for...

Platinum-group elements in southern Africa: mineral inventory and an assessment of undiscovered mineral resources Platinum-group elements in southern Africa: mineral inventory and an assessment of undiscovered mineral resources
The platinum-group elements, platinum, palladium, rhodium, ruthenium, iridium, and osmium, possess unique physical and chemical characteristics that make them indispensable to modern technology and industry. However, mineral deposits that are the main sources of these elements occur only in three countries in the world, raising concerns about potential disruption in mineral supply. Using

Porphyry copper assessment of Central America and the Caribbean Basin Porphyry copper assessment of Central America and the Caribbean Basin
Mineral resource assessments provide a synthesis of available information about distributions of mineral deposits in the Earth’s crust. The U.S. Geological Survey prepared a probabilistic mineral resource assessment of undiscovered resources in porphyry copper deposits in Central America and the Caribbean Basin in collaboration with geoscientists from academia and the minerals industry...

Assessment of undiscovered sandstone copper deposits of the Kodar-Udokan area, Russia Assessment of undiscovered sandstone copper deposits of the Kodar-Udokan area, Russia
Mineral resource assessments integrate and synthesize available information as a basis for estimating the location, quality, and quantity of undiscovered mineral resources. This probabilistic mineral resource assessment of undiscovered sandstone copper deposits within Paleoproterozoic metasedimentary rocks of the Kodar-Udokan area in Russia is a contribution to a global assessment led by...

Descriptive and geoenvironmental model for Co-Cu-Au deposits in metasedimentary rocks Descriptive and geoenvironmental model for Co-Cu-Au deposits in metasedimentary rocks
Introduction This report is a revised model for a specific type of cobalt-copper-gold (Co-Cu-Au) deposit that will be evaluated in the next U.S. Geological Survey (USGS) assessment of undiscovered mineral resources in the United States (see Ferrero and others, 2012). Emphasis is on providing an up-to-date deposit model that includes both geologic and geoenvironmental aspects. The new...

Rangewide glaciation in the Sierra Nevada, California Rangewide glaciation in the Sierra Nevada, California
The 600-km-long Sierra Nevada underwent extensive Pleistocene glaciation except for its southernmost 100 km. Presently, ∼1700 small glaciers and ice masses near the crest of the range occur above 3250 m in elevation; these covered an area of ∼50 km2 in 1972. Fourteen of the largest glaciers decreased by about one half in area during the period from 1900 to 2004. Rock glaciers, generally...
