Critical minerals are usually found in ore deposits that are deemed vital to economic and national security. National Geochemical Database on Ore Deposits: New data featuring fusion digestion (NGDOD) analytical methods contains chemistry and geologic information for 16,579 ore and ore-related rock and mineral samples from mineral deposits and mining districts in the United States. Geochemical data sets from various mineral deposits were submitted by geologists of the Systems Approach to Critical Minerals Inventory, Research, and Assessment project within the U.S. Geological Survey Mineral Resource Program. The data sets represent 22 mineral system types and 85 mineral deposit types, and were derived by using fusion digestion analytical methods that provide a near complete digestion and decomposition of the analyzed samples. The NGDOD also includes data from 966 rock samples of the Global Geochemical Database for Critical Minerals in Archived Ore Samples (2020) and 370 rock samples of the National Geochemical Database on Ore Deposits: Legacy data (2021). Much of this data has been compiled and is additionally found within smaller contributions. Please see references for the original sources of the data. The data may also have been utilized in interpretive manuscripts that have been published in peer-reviewed journals or other U.S. Geological Survey reports that can be found through cursory literature searches using authors and locations. The National Geochemical Database on Ore Deposits is a tool used in the study of mineral systems and their deposit types as an approach to research and evaluate critical minerals inventories, and to assess the critical mineral potential of previously mined U.S. ore deposits and associated mining districts. This database is a featured part of the U.S. Geological Survey Mineral Resource Program's Systems Approach to Critical Minerals Inventory, Research, and Assessment project that is responsible for inventory, updated deposit and system models, and resource assessments of both major commodities and critical minerals that may be produced as principal-, co- or by-products. These data will also create research opportunities for exploring the processes that enrich these elements in ore systems and to assist leading ore system experts to update models so that they include critical minerals for future mineral assessments. Database Structure: National Geochemical Database on Ore Deposits: New data featuring fusion digestion analytical methods (NGDOD) is provided in Microsoft (MS) Access and comma-separated values (CSV) formats. The native data set MS Access relational database, designed to accommodate the MS Access limitations of 256 data fields for a single table and 6 kilobytes of data for a single record, is described here. Data are contained in 14 tables (MS Access 2016 and comma-separated ASCII text formats). The 6 primary database tables (listed below) contain quantitative analytical results, sample data, field site information, geologic and mineralogic data. The primary tables are: Geol: table of spatial, geologic and descriptive attributes for rock and mineral samples; includes records for both original and resubmitted samples Chem: table of all chemical data compiled for rock and mineral samples; total major element concentrations expressed as oxides are converted to element basis BV_Ag_Cr: table of best value chemical data - elements silver through chromium - for rock and mineral samples BV_Cs_Lu: table of best value chemical data - elements cesium through lutetium - for rock and mineral samples BV_Mg_Sb: table of best value chemical data - elements magnesium through antimony - for rock and mineral samples BV_Sc_Zr: table of best value chemical data - elements scandium through zirconium - for rock and mineral samples Analytical method information and analytical method bibliography lookup tables (listed below) found in the NGDOD provide references for quantitative results. A reference table of field name definitions (table DataDictionary) and this FGDC metadata record can assist the user in understanding the names and content of database fields. The lookup and reference tables are: DepositTypes: table of mineral system and deposit types, from U.S.Geological Survey (USGS) Open-File Report 2020-1042 Geol_Biblio: table of bibliographic references linked to chemical and geospatial data; eleven references are informational and not directly linked to data Parameter: analytical method parameters used to obtain chemical data Parameter_Rank: analytical method parameters, sorted by species and ranked by preference (best value) AnalyticMethod: table of analytic methods used to obtain chemical and physical data AnalyticMethod_Biblio: references for analytic methods used to obtain chemical data LabName: laboratories, agencies or organizations that performed chemical analysis DataDictionary: field name descriptions for all tables in the databases This structure provides for efficient storage of information and for data verification. Data may be extracted from the NGDOD to meet specific user needs by constructing user-defined queries.

Denver CO 80225 United States 303-236-1882 303-236-3200 rtaylor@usgs.gov Microsoft Access 2016 These data were compiled from legacy tables and laboratory information management (LIMS) tables of the National Geochemical Database (NGDB), and some of the data sets have been previously published. Most of these data have been verified by the Analytical Chemistry Project of the USGS Geology, Geophysics and Geochemistry Science Center. A small data set of older chemical determinations from Alaska samples have been included in the National Geochemical Database on Ore Deposits: New data featuring fusion digestion analytical methods (NGDOD) as they represent the original determinations that have been merged with recent determinations from the same samples that have since been reanalyzed using more modern and quantitative analytical methods. See metadata Process Step 1 and metadata References Granitto and others (2019, 2024) for further information regarding these samples. Following compilation, the data for each attribute was checked for outliers to ensure accuracy. Quality assurance and quality control (QAQC) procedures were utilized and varied over the time of sample processing and analysis, and descriptions of the QA measures are not described in this database. Data from field sample-site duplicates and analytical replicates (splits of a single sample to check laboratory precision) are included in the database. Agency and contract laboratories reporting these analyses used standard reference materials to calibrate their analyses. This dataset was derived from the USGS National Geochemical Database (NGDB). Errors discovered in the data checking process were reported to the NGDB. The following criteria were chosen for selecting data for the rock and mineral sample data set: Each sample must have a unique identifying number, SACM_ID. Each sample must have a latitude and longitude, and plot in the US; eight of them plot on the Blake Plateau of the outer continental shelf of the Atlantic Ocean off the coast of South Carolina but within the US exclusive economic zone (EEZ). Each sample must be identified as rock or mineral. Each sample was considered useful in the study of mineral deposits by the Systems Approach to Critical Minerals Inventory, Research, and Assessment project. Each sample was analyzed by a multi-element analytical method that includes a fusion digestion process. Each analytical determination must be linked to a unique identifying number, CHEM_ID. Each analytical determination must be identified by analyte. In addition, samples that could be identified as a processed derivative of geologic material, with the exception of heavy-mineral concentrate insoluble residues, were removed from the data set. This included single minerals, mineral separates, rock coatings, weak partial digestions, and leachates. The samples in this data set were collected for a variety of purposes. Not all samples were subject to the same sample preparation protocol or the same analytical protocol. The samples have been analyzed using documented techniques. For some elements, the methods of chemical analysis were the same throughout a study, while for others, the methods changed as analytical technology improved. Some of the methods used were specifically designed to give a concentration value based on a partial digestion or extraction of the sample. For these methods elements tightly bound in the structure of silicates in the sample are not measured because the partial digestion does not enable the analytical equipment to measure them. Thus, measures derived from partially digested samples may not be directly comparable with measures of the same chemical species obtained from fully digested samples. This data set provides chemical data for Ag, Al, As, Au, B, Ba, Be, Bi, Br, Ca, Cd, Ce, Cl, Co, Cr, Cs, Cu, Dy, Er, Eu, F, Fe, Ga, Gd, Ge, Hf, Hg, Ho, In, Ir, K, La, Li, Lu, Mg, Mn, Mo, Na, Nb, Nd, Ni, Os, P, Pb, Pd, Pr, Pt, Rb, Re, Rh, Rn, Ru, S, Sb, Sc, Se, Si, Sm, Sn, Sr, Ta, Tb, Te, Th, Ti, Tl, Tm, U, V, W, Y, Yb, Zn, Zr, ferrous oxide, sulfate, forms of carbon, forms of water, and loss on ignition. In addition, the data set provides location and descriptive information for each sample. Not all the descriptive fields contain information for a particular sample because it was not recorded by the submitter or because it was never entered into the source database. No sample will contain analyses for all possible elements. The analytical methods used were selected by the sample submitter based on the goals of the scientific investigation for which the sample was analyzed and will vary throughout the data set. The analytical methods, sample preparation protocols, and quality control protocols used for various sample media by the USGS are documented in the NGDOD table AnalyticMethod_Biblio. 1) Coordinates: Most of the more recently submitted samples were located using Global Positioning System (GPS) receivers, but there are no data fields in the National Geochemical Database (NGDB) that indicate GPS was actually used to locate specific samples. The locations determined by GPS should be accurate to the nearest latitude or longitude second. Older sample locations were determined primarily from USGS topographic maps of various scales. Sometimes these coordinates were determined directly from the original maps using a digitizing board. In other cases, a clear overlay with a coordinate grid was used to visually estimate the sample position on the map. The positional accuracy is dependent on the scale of the map from which the location was estimated as well as the care taken by the individuals who plotted the sample or who made the coordinate determination. The coordinates have positional accuracy to 0.0001 of a degree, regardless of their precision. The determination of coordinates from field sheets was a time consuming and error prone process. To facilitate the analysis of samples, a decision was made by the USGS to allow samples to be submitted to the laboratory using only the coordinates for the lower right (usually southeast) corner of the submitter's working field map on which the samples could be plotted, which was most commonly a 7.5' or 15' quadrangle map. In theory, the precise coordinates for these samples would be determined and later added to the database. In practice, most of these more precise coordinates were used in resultant USGS Open-File data releases or publications but were never entered back into the NGDB. There are 144 corner coordinate sample locations in the NGDOD that have latitude and longitude entries that end in 0.0, 0.125, 0.25, 0.3275, 0.5, 0.625, 0.75, or 0.875 values. When sample submitters reported locations as degrees, minutes, and seconds of latitude and longitude the accuracy should be within a few seconds. When submitters only reported locations as degrees and minutes the accuracy is only to the nearest minute. When submitters only reported the corner coordinates of their field map, the accuracy is only to the nearest 7.5 or 15 minutes. 2) Datum and Earth Ellipsoid or Spheroid: When coordinates were submitted from GPS receivers or when the source of the coordinates was known, the datum and spheroid used in the projection were provided. For much of the data, these fields were empty. Since most of the older coordinate data in the database were determined from published maps, the best assumption is that the appropriate datum and spheroid is the one most used for those types of maps. In the United States, most field maps were USGS topographic maps that used NAD27 (1927 North American datum) based on the Clarke 1866 ellipsoid. A review of NGDB sample locations that have datum information shows that the usage of WGS84 and NAD83 datums has overtaken that of NAD27 by 2005. Using the wrong ellipsoid or datum may result in a location that is offset by up to a hundred meters. Geographic coordinates in the fields LATITUDE and LONGITUDE in the Geol table for all records not in WGS84 datum were projected to WGS84 datum. Vertical position refers only to drill core sample depth for rock samples or for various recorded depths in drillholes as cited by sample submitters, who often did not provide units of measurement. STEP 1: NGDB DATA COMPILED. Geochemical and geospatial data from rock and mineral samples collected in the US that were analyzed by a multi-element analytical method that includes a fusion digestion process were retrieved from the National Geochemical Database (NGDB) and the U.S. Geological Survey Geology, Geophysics and Geochemistry Science Center (GGGSC) laboratory information management system (LIMS), except for 1,655 samples collected in Alaska that were published in early 2024 in the Alaska Geochemical Database Version 4.0 (AGDB4) including best value data compilations for rock, sediment, soil, mineral, and concentrate sample media. Alaska data also included in the NGDOD are from 71 rock samples that were previously published in the Global geochemical database for critical minerals in archived mine samples (Granitto and others, 2020), and from 272 rock samples from LIMS that were analyzed too recently to be included in the AGDB4. A check was done to ensure that all qualified data of team members of the Systems Approach to Critical Minerals Inventory, Research, and Assessment project (SACM) was included. Some of these data had been previously included in references listed in NGDOD table Geol_Biblio). Legacy data from the USGS Branches of Exploration Research (1977-1984), Analytical Laboratories (1968-1980) and Geochemistry (1989-1994), and the USGS Mineral Resources Program (2008-2012) are included in this compilation. These data were reformatted using the format of the Alaska Geochemical Database, Version 4.0 (AGDB4) at https://doi.org/10.5066/P14THGQH. 2023 Ryan D.

The NGDB data set was queried for rock and mineral geochemical data that met specific project criteria of the SACM. Selected for the NGDOD were samples where element(s) were detected at anomalous or moderately anomalous concentrations, or related to known mineral deposits as chemically anomalous ore samples or less anomalous wallrock and gangue samples. Information regarding mine name, mineral deposit name and mining district name associated with these analyzed samples was entered wherever possible using the data references of the U.S. Geological Survey USMIN Mineral Deposit Database (USMIN), Mineral Resource Data System (MRDS) or Alaska Resource Data File (ARDF). 2018 Ryan D.

The geologic and chemical attributes of NGDOD rock and mineral samples were reviewed by SACM project mineral deposit experts to determine which mineral system and mineral deposit type(s) these samples were most associated with, using the mineral system and deposit type classification scheme from USGS Earth Mapping Resources Initiative (Earth MRI) project, as described in USGS Open-file Report 2020-1042. The work of Albert H. Hofstra, Garth E. Graham, George N. Case, and Erik R. Tharalson was critical in completing this process step. 2021 Ryan D.
