The U.S. Geological Survey (USGS), in cooperation with the U.S. Army Corps of Engineers (USACE), conducted a study from June 2014 through November 2014 to identify the hydrologic, chemical and microbiologic processes affecting declining pump performance and frequent pump failure at a confined disposal facility (CDF) in East Chicago, Indiana. Solid phase samples were collected from monitoring and extraction wells from September to November 2014. Qualitative and quantitative x-ray diffraction (XRD) analyses were done on eight samples of pump scrapings collected from five extraction wells (EW-4C, EW-4D, EW-11D, EW-20D) and one monitoring well (MW-4B). The data set includes a comma-separated value (.csv) file of XRD...

A sample of hydrothermally mineralized foraminifera ooze (D28A) was collected via dredge from a seamount within the Tuvalu Exclusive Economic Zone in the Pacific Ocean during cruise RR1310 funded by the National Science Foundation aboard the R/V Roger Revelle in 2013. USGS scientists requested these ferromanganese crust samples from the Oregon State University Marine and Geology Repository where they had been archived. Ferromanganese crust samples were sent to USGS for subsampling and x-ray diffraction analyses. Powder x-ray diffraction data for three layer-fractions of the hydrothermal sample are provided here. Measurements were made after heating to 115 C for 48 hours to test the stability of the phyllomanganate...

These data were collected from the TOPGUN-SODA10 2AK core collected in 2010 by LacCore (University of Minnesota), the USGS. and the University of California (U.C.) Berkeley. The 8.9 meter length core had stable isotopes of oxygen and carbon sampled every 10 millimeters or so, and diatoms samples at every 50 millimeters to 200 millimeters depending on the depth in the core. mineralogic data were collected using X-ray diffraction and grain-size analysis were done at various depths. These data are used to interpret the Holocene and late Pleistocene hydrology and paleoclimate of the lake and the region. The interpretation can be found in: Rosen, M.R., Reidy, L., Starratt, S., Zimmerman, S., in review, Middle Holocene...

This dataset contains reflectance and transmission spectra of unexpanded and expanded vermiculite ore, and handpicked flakes of phlogopite, hydrobiotite, and vermiculite. These samples were collected from mines near Enoree, South Carolina; Libby, Montana; Louisa, Virginia; Palabora, Llano, Texas; and South Africa. Spectra are identified as either reflectance or transmission in the alphanumeric file names and correlate to specpr record numbers designated in the manuscript figures in which they are shown. These transmission spectra were converted to absorbance in many of the figures. Spectra of talc, fibrous richterite amphibole, and serpentine are from well characterized samples from Feiser Mine, Ruby Mountains,...

Samples of the crater lake water were filtered in the field with a 0.45 micron filter. Subsequently, additional precipitates formed in the solute-rich samples (secondary precipitates) which were subsequently filtered in the lab with a 0.45 micron filter. The mineralogy of secondary precipitates for samples HM19-01 and HM20-01A,B,C that were collected on 10/26/2019 and on 1/17/2020, respectively was determined by X-ray diffraction (XRD). Analysis was carried out at the British Natural History Museum with a Enraf-Nonius PDS120 diffractometer equipped with a primary Germanium (111) monochromator and an INEL 120° curved position sensitive detector (PSD). Data were collected from 7-120° 2θ using Co Kalpha1 radiation...

This dataset is a compilation of samples collected from draining mine adits, including water and mineral precipitates, from several mines in California and Colorado. The Golinsky, Copper Bluff, and Afterthought Mines (located in northern California) and the Gold King mine (located in southern Colorado) have historically operated to recover metals including copper, lead, zinc, gold, silver and other resources (Albers and Robertson, 1961; USGS, 2005; USEPA, 2015). Data reported include field parameters, water chemistry, solid phase mineralogy and solid phase chemistry. Water samples collected from the four mine sites in 2019 were analyzed for unfiltered and filtered (0.1-0.45 micrometer) major and trace elements and...

The X-ray diffraction (XRD) pattern library presented here is intended for qualitative or quantitative mineralogical analysis of geologic materials. The original collection of 169 reference diffractograms was released by Eberl (2003) as a part of RockJock, a USGS program for quantitative analysis of mineralogy, which included patterns of many of the major rock-forming minerals needed to analyze a wide variety of rocks, sediments, soils, and other geologic materials. The library was generated from mineral samples collected from the environment or synthesized in the laboratory. In the case of geologic samples, every effort was made to collect as pure a mineral specimen as possible. The purpose of this data release...

A suite of slate samples collected along a 2 km transect crossing the Lishan Fault in central Taiwan were evaluated to assess the role of ductile strain energy in natural graphitization at greenschist facies metamorphic conditions. Scanning electron microscope (SEM) imaging documents phyllosilicate and quartz replacement textures consistent cleavage development via dissolution-precipitation processes that increase in intensity from east to west. X-ray diffraction data reveal an east-to-west linear decrease in the full-width-at-half-maximum (FWHM) values of the 004 muscovite peaks and shifts towards higher 2θ (lower d) values. Rietveld refinements required two distinct muscovite populations and muscovite microstrain...
