Mineral abundances within bulk and size-fractionated mine waste from sampled historical waste piles from the Tar Creek Superfund Site, Oklahoma, U.S.A., were determined by Mineral Liberation Analysis (MLA) and X-Ray Diffraction (XRD). Data and methods reported are part of a research study published here: White, S.J.O., Piatak, N.M., McAleer, R.J., Hayes. S.M., Seal, R.R. II, Schaider, L.A., Shine, J.P.

Elemental concentrations for bulk and size-fractionated mine waste from sampled historical waste piles from the Tar Creek Superfund Site, Oklahoma, U.S. were determined after dissolution via acid digests or a sodium peroxide fusion. Elemental concentrations were determined for the leachate from a simulated rainwater leach of mine wastes.

Electron microprobe analyses of sphalerite (ZnS) and hemimorphite (Zn4Si2O7(OH)2·H2O) from sampled historical waste piles were conducted with a specific focus on germanium (Ge). In mine wastes at the Tar Creek Superfund Site, Oklahoma, USA, Ge is associated with ZnS (sphalerite) as expected, but weathering in the waste piles has led to a significant amount of Ge being incorporated into a zinc-silicate, hemimorphite.

Germanium redistribution during weathering of Zn mine wastes: implications for environmental mobility and recovery of a critical mineral"

Oxidation state and bonding environment of Ge in minerals within mine waste from sampled historical waste piles from the Tar Creek Superfund Site, Oklahoma, U.S. were determined by linear combination fits from x-ray absorption near edge spectroscopy (XANES) analysis. Ge content in quartz within these wastes was determined using XANES edge steps, and Ge content in sphalerite was compared using XANES edge steps versus electron microprobe analyses.

The Geochemical and geologic database for Mesoproterozoic igneous rocks and iron oxide-apatite-rare earth element (IOA-REE) and iron oxide-copper-cobalt-gold (IOCG) deposits of Southeast Missouri, 2016-2017 'Geochemical Database for Iron Oxide-Copper-Cobalt-Gold-Rare Earth Element Deposits of Southeast Missouri, 2016-2017' (MO_ROCK_IOCG_REE_GX2017) contains new geochemical data compilations for samples from Mesoproterozoic igneous rocks and iron oxide deposits of the Precambrian basement of southeast Missouri. Each sample has one "best value" determination for each analyzed species, greatly improving speed and efficiency of use. MO_ROCK_IOCG_REE_GX2017 was created and designed to compile whole-rock and trace element data from southeast Missouri in order to facilitate petrologic studies, mineral resource assessments, the definition and statistics of geochemical baseline values, and areas of anomalous concentrations of metals. This relational database serves as a data archive in support of present and future geologic and geochemical studies of IOA-REE and IOCG type deposits, and contains data tables in two different formats describing historical and new quantitative and qualitative geochemical analyses. It is designed to be used with the earlier ScienceBase data release of Day and others, 2017. The analytical results were determined by 19 laboratory analytical methods on 215 rock samples collected during two phases from outcrop and drill core sites from throughout the entire St. Francois Mountains terrane made by the U.S. Geological Survey (USGS). From 2013 to 2017 the USGS collected and analyzed 119 samples, and 96 samples collected and analyzed from 1989 to 1994 were reanalyzed in 2017 using modern analytical methods of higher precision. The data presents the most precise analytical approach to report the best value for each element. The original data from the 96 samples are currently maintained in the USGS National Geochemical Database (NGDB), and data from the 119 samples plus the reanalysis data of the 96 samples will soon be added. The data of the IOCG-REE_GX were checked for accuracy regarding sample location, sample media type, and analytical methods used. Reference: >Day, W.C.

This U.S. Geological Survey (USGS) data release contains data from stream water, groundwater/springs, and sediment samples collected from legacy mine land (LML) sites in central Colorado. The sites were selected using a GIS-based approach that integrated regional geological and geochemical datasets with known mine features and satellite data identifying hydrothermal alteration (ASTER) to identify LML-impacted watersheds with low natural background or metal concentrations slightly above aquatic life standards. The central Colorado watersheds selected for preliminary investigation included 1) McNasser Gulch, 2) upper South Fork Lake Creek, 3) Saints John Creek, and 4) Hall Valley (north fork of South Platte River). Reconnaissance sampling of surface water, groundwater, and sediment (August 2019) to identify sources of trace element contamination in each watershed. Follow-up sampling in the Hall Valley watershed (August 2020) provided flow and concentration data for the four largest surface inflows to a headwater pond and additional locations below the pond outlet. Metal loads at these locations were calculated as the product of flow and concentration.

From June to September 2017, the United States Geological Survey (USGS) collected a total of 116 surficial sediment and bedrock samples from abandoned mine wastepiles, ephemeral channels below wastepiles, nearby outcrops, and background areas representative of the undisturbed lithology on the western slope of the northern half of the Oquirrh Mountain Range, approximately 20 miles southwest of Salt Lake City, Utah. The sample locations can be spatially clustered into four groups: the Bates Canyon group in the foothills below Bates Canyon; the Middle Canyon group in Middle Canyon; the Ridgeline group within the Bingham Mining District located at or near the Tooele-Salt Lake County border on the Oquirrh Mountain ridge; and the Stockton group within the historic Stockton Mining District (also known as the Rush Valley Mining District). Mining operations within the study area began in the mid-1860s and primarily targeted copper, gold, iron, lead and zinc deposits in the Pennsylvanian-Permian Oquirrh Group (Krahulec, 2018). Geochemical analyses were completed through a third-party contract by AGAT Laboratories. Samples were analyzed for 49 major, minor, and trace elements using Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) and Inductively Coupled Plasma Mass Spectrometry (ICP-MS) methods (Ag, Al, As, Ba, Be, Bi, Ca, Cd, Ce, Co, Cr, Cs, Cu, Fe, Ga, Hf, In, K, La, Li, Lu, Mg, Mn, Mo, Na, Nb, Ni, P, Pb, Rb, S, Sb, Sc, Se, Sn, Sr, Ta, Tb, Te, Th, Ti, Tl, U, V, W, Y, Yb, Zn, Zr).
