This data release provides multi-element data for drill core samples from the Mesoproterozoic Nonesuch Formation and Copper Harbor Conglomerate at the Copperwood copper deposit, Michigan, USA. Copper was determined by assay, and sulfur by inductively coupled plasma-optical emission spectrometry (ICP-OES) after aqua regia digestion for most samples. Multi-element whole rock analyses were determined for selected samples. The Copperwood copper deposit is a sediment-hosted stratiform copper deposit in the Presque Isle Syncline of the Upper Peninsula of Michigan. The deposit has a 2018 mineral resource estimate of 42.2 million metric tons (Mt) of measured plus indicated mineral resources in the Lower Copper Bearing Sequence...

This data release provides electron microprobe analyses of ore minerals from the Copperwood sediment-hosted stratiform copper deposit in the Upper Peninsula of Michigan. The minerals include bornite, chalcocite, native copper, native silver, and pyrite. Minerals were analyzed for Ag, As, Co, Cu, Fe, Hg, Ni, Pb, S, Sb, and Zn. Results with acceptable totals that lie between 98.5 and 101.5% show that these minerals are stoichiometric, with very limited substitution of other elements. The Copperwood copper deposit is a sediment-hosted stratiform copper deposit in the Presque Isle Syncline of the Upper Peninsula of Michigan. The Lower Copper Bearing Sequence has a 2018 mineral resource estimate of 42.2 million metric...

This dataset consists of records for over 1,500 mineral facilities in Africa and the Middle East. The mineral facilities include mines, plants, mills , or refineries of aluminum, cement, coal, copper, diamond, gold, iron and steel, nickel, platinum-group metals, salt, and silver, among others. Records include attributes such as commodity, country, site, company name, plant capacity if applicable, and generalized coordinates. The data were compiled from multiple sources, including the 2004 USGS Minerals Yearbook (Africa and Middle East volume), minerals statistics and information from the USGS minerals information Web site (http://minerals.usgs.gov/minerals/), and data collected by USGS minerals information country...

Geologists from the Alaska Division of Geological & Geophysical Surveys (DGGS) Mineral Resources Section conducted four weeks of helicopter-supported mapping and fieldwork from June 26 through July 24, 2013. The Styx River project in the Lime Hills C-1 Quadrangle was part of the State-funded Airborne Geophysical/Geological Mineral Inventory (AGGMI) program as part of the State's Strategic Minerals Assessment Project, an initiative designed to evaluate Alaska's potential for rare-earth elements, PGEs, and other similarly supply-challenged resources. The Styx River project area has active and ongoing mineral exploration for deposit types including porphyry copper/molybdenum/gold, reduced intrusion-related gold, and...

This data release contains geochemical data from selected U.S. Geological Survey (USGS) projects from the 1960s-1980s that were previously unpublished as digital data. The objective of those projects was to describe the geology, determine petrologic and geochemical characteristics, or to evaluate the mineral resource potential of Federal Lands and adjacent study areas. These data comprise geochemical analyses from 36,498 samples--27,223 rock samples, 4,091 sediment samples, 2,351 soil samples, 330 heavy-mineral pan concentrate samples, 297 organic material samples, 58 mineral samples, 27 water samples, 11 miscellaneous samples, and 2,110 unspecified media samples. More than 78 percent of these samples were analyzed...
