This Titanium_vanadium_deposits.csv file contains data about titanium-vanadium deposits hosted in mafic-ultramafic layered intrusions and massif anorthosite intrusions around the world. It lists the deposits and associated information such as the host intrusion, location, grade, and tonnage data, along with other miscellaneous descriptive data about the deposits. Also included with this data release are the following files: Titanium_vanadium_deposits.shp file, which duplicates the information in the Titanium_vanadium_deposits.csv file in a spatial format for use in a GIS; Titanium_vanadium_column_headings.csv file, which correlates the column headings in the Titanium_vanadium_deposits.csv file with the attribute...
This dataset tabulates input data for simulations of undiscovered copper resources in porphyry copper deposits that were done using the EMINERS computer program (Duval, J.S., 2012, Version 3.0 of EMINERS—Economic Mineral Resource Simulator: U.S. Geological Survey Open-File Report 2004–1344, http://pubs.usgs.gov/of/2004/1344) as part of a global mineral resource assessment. The input data consist of information for 163 permissive tracts for porphyry copper deposits in 7 world regions. A GIS of the permissive tracts and selected data are available in Dicken, C.L., Dunlap, Pamela, Parks, H.L., Hammarstrom, J.M., and Zientek, M.L., 2016, Spatial database for a global assessment of undiscovered copper resources: U.S....
In response to the growing demand for information on the global mineral-resource base, the U.S. Geological Survey (USGS) completed assessments for undiscovered resources of selected types of mineral deposits (https://minerals.usgs.gov/global). This data release tabulates data for simulations of amounts of copper resources in undiscovered porphyry copper deposits that were done for the Global Mineral Resource Assessment. For this assessment, 163 areas (permissive tracts) in 7 regions of the world that may contain porphyry copper deposits that had sufficient information to make a quantitative assessment of undiscovered copper resources were considered. Probabilistic estimates of numbers of undiscovered deposits were...

This dataset includes TIFF (Tagged Image File Format) images of graphic drill core logs showing associated drill core information, a TIFF image of the explanation for the lithology and structure sections of the logs, an Esri shapefile of the locations of the drill holes, and fourteen individual .csv files of tabular data that were compiled from handwritten drill core logs. The drill core is from the Nye Basin area of the Stillwater Complex, Montana and was drilled from 1968 to 1982 by the Anaconda Copper Company. The data shown in the graphic drill logs and contained within the .csv files includes lithologic, structure, grain size, susceptibility, chromite, sulfide, copper, and nickel mineralization information....
This Titanium_vanadium_column_headings.csv file correlates the column headings in the Titanium_vanadium_deposits.csv file with the attribute field names in the Titanium_vanadium_deposits.shp file and provides a brief description of each column heading and attribute field name. Also included with this data release are the following files: Titanium_vanadium_deposits.csv file, which lists the deposits and associated information such as the host intrusion, location, grade, and tonnage data, along with other miscellaneous descriptive data about the deposits; Titanium_vanadium_deposits.shp file, which duplicates the information in the Titanium_vanadium_deposits.csv file in a spatial format for use in a GIS; Titanium_vanadium_deposits_concentrate_grade.csv...
This dataset tabulates summary statistics for estimates of amounts of copper in undiscovered porphyry copper deposits by world region and for the globe. Data re reported by region, by aggregation method (randomized and sorted), and by selected statistics. These include quantiles, means, standard deviations, standard error of the mean , and Upper and Lower 95% of the mean.
This dataset tabulates sorted simulation results for amounts of copper in metric tons. The data are output from the EMINERS computer program (Duval, J.S., 2012, Version 3.0 of EMINERS—Economic Mineral Resource Simulator: U.S. Geological Survey Open-File Report 2004–1344, http://pubs.usgs.gov/of/2004/1344) that were copied into a worksheet. The program was run with the input tabulated in the related worksheet Permissive tracts and input data
This Titanium_vanadium_deposits_references.csv file contains the full and abbreviated references used in the Titanium_vanadium_deposits_concentrate_grade.csv, Titanium_vanadium_deposits.csv, and Titanium_vanadium_deposits.shp files. Also included with this data release are the following files: Titanium_vanadium_deposits.csv file, which lists the deposits and associated information such as the host intrusion, location, grade, and tonnage data, along with other miscellaneous descriptive data about the deposits; Titanium_vanadium_deposits.shp file, which duplicates the information in the Titanium_vanadium_deposits.csv file in a spatial format for use in a GIS; Titanium_vanadium_column_headings.csv file, which correlates...
This dataset tabulates aggregated data for simulations of undiscovered copper resources in porphyry copper deposits that were done using the EMINERS computer program (Duval, J.S., 2012, Version 3.0 of EMINERS—Economic Mineral Resource Simulator: U.S. Geological Survey Open-File Report 2004–1344, http://pubs.usgs.gov/of/2004/1344) as part of a global mineral resource assessment. The data in this table are the regional totals of the 4,999 sorted and randomized totals from the child entities Simulation results_sorted and Simulation results_randomized. These data are used as input for the Summary statistics by region.csv child item..
This Titanium_vanadium_deposits_concentrate_grade.csv file contains data about the concentrate grade of titanium-vanadium deposits hosted in mafic-ultramafic layered intrusions and massif anorthosite intrusions around the world. Also included with this data release are the following files: Titanium_vanadium_deposits.csv file, which lists the deposits and associated information such as the host intrusion, location, grade, and tonnage data, along with other miscellaneous descriptive data about the deposits; Titanium_vanadium_deposits.shp file, which duplicates the information in the Titanium_vanadium_deposits.csv file in a spatial format for use in a GIS; Titanium_vanadium_column_headings.csv file, which correlates...
This dataset tabulates randomized simulation results for amounts of copper in metric tons in 163 permissive tracts for undiscovered porphyry copper deposits. The data from the child item Simulation results_sorted.csv for each permissive are randomized to allow aggregation of regional and global data using an assumption of statistical independence. This was done by generating a column of 4,999 random numbers and resorting the 4,999 sorted simulations by those random numbers. The randomized distributions for each permissive tract in a region were then summed to compute regional and global totals. For an explanation of aggregation assumptions and underlying mathematics, see Schuenemeyer, J.H., Zientek, M.L, and Box,...
This file includes strike and dip information for the area of the Stillwater Complex, located in southwestern Montana. This dataset was created from pre-existing digital strike and dip information and from digitizing strike and dip locations from georeferenced map images. The data includes information about the strike and dip locations; the geologic unit and rock type the measurement was taken on; information about the source map, such as map title and scale; and other miscellaneous information.
