Online_Linkage: https://doi.org/10.5066/P9WHRLXH Description: Abstract: The geochemical data included here were generated as part of the Earth Mapping Resources Initiative (Earth MRI), which was developed by the U.S. Geological Survey (USGS) in response to a Federal directive calling on various Federal agencies to address potential vulnerabilities in the Nation’s supply of critical mineral resources. Earth MRI is a partnership between the USGS, State Geological Surveys, and industry coordinating with other federal agencies to accomplish the mission. The primary purpose of this initiative is to identify potentially mineralized areas containing critical minerals by gathering new basic geologic data about the United States and its territories and to make these data publicly available through the Earth MRI web applications (https://www.usgs.gov/special-topic/earthmri/maps). The USGS is working in partnership with the State Geological Surveys to collect data and improve knowledge of the geologic framework in areas that may have the potential to contain undiscovered critical mineral resources. This data release includes all geochemical data generated by each project partnership funded through Earth MRI and will be updated periodically as additional geochemical data from these projects becomes available. Purpose: The goal of Earth MRI is to improve our knowledge of the geologic framework in the United States and to identify areas that may have the potential to contain undiscovered critical mineral resources. Enhancement of our domestic mineral supply will decrease the Nation’s reliance on foreign sources of minerals that are fundamental to our security and economy. These geochemical data were collected to support regional synthesis/synoptic surveys and geologic mapping by individual projects funded by Earth MRI.

Thus, some of the information is preliminary. For example, the specific rock name for igneous samples may be based on initial field observations and may not be consistent with the final analytical results provided here. The sample descriptive information is as complete and accurate as was provided during submittal. No attempt was made to go back and supplement or correct any fields unless errors were identified by the original submitter. Some of the samples submitted for reanalysis were retrieved from the USGS National Geochemical Sample Archive. The sample descriptive information for these previously submitted samples was derived from data compilations such as the National Geochemical Database (https://mrdata.usgs.gov/ngdb/) or the Alaska Geochemical Database v.3.0 (Granitto & others, 2019; https://doi.org/10.5066/P98NHRAD) 2) Analytical Data: All analytical data in this data release come from recently completed analyses at AGAT Laboratories Ltd. under contract with the USGS. AGAT Laboratories is accredited to ISO/IEC 17025:2005 and certified to the ISO 9001:2008 standard. The accuracy of the analytical data was evaluated and confirmed by the use of Geologic Reference Materials (GRMs) and Quality Assurance/Quality Control (QA/QC) measures. The laboratory inserted a reagent blank and an internal GRM with every batch of 20 samples. Within every job of samples submitted to the laboratory, the USGS inserted a set of USGS in-house GRMs at the rate of 10% that were blind to the laboratory. Specific GRMs were chosen based on the sample media and requested analytical methods since GRMs often lack expected values for certain elements or constituents and may not be useful for every analytical method. In addition to the GRMs, at least one randomly chosen sample per job was split and submitted blind to the laboratory as an analytical duplicate. All USGS GRMs, as well as the original and duplicate analytical split samples are included and identified herein. “Preferred” and “Mean” values for USGS GRMs used for Earth MRI projects are included in the QAQC_Values table. A full description of the QA/QC process is given in this metadata file within the Quality Assurance/Quality Control and Data Approval process step. Additional reference materials are sometimes included by the submitter and although they may be identified as such in the data, these were not included in the quality control assessment used to approve the data returned by the laboratory, nor were expected values for these reference materials included in the QAQC_Values table. 3) Informational Values: The ICPOES_MS-60 analytical results for boron (B) and rhenium (Re) are considered to be informational. Boron is informational since there are few reference materials with the certified B values needed to reliably characterize the performance. Rhenium is informational since there is not an established preferred value for the USGS reference materials and there is insufficient available data to calculate means for meaningful comparisons. In addition to these elements, there are no established preferred values for these reference materials when analyzed by the recently added C_AQUA_REGIA partial leach method. Results were compared to averages taken from a small sample size and may not be a reliable indicator of method performance. Laboratory replicates and reference materials performed adequately for all fields with informational values. 4) Detection Limits: Despite advances in analytical methods and instrumentation, some element concentrations still fall outside the method's Lower and Upper Detection Limits. (See the Limits_AnalyticalMethods table for a list of all Lower and Upper Detection Limits by analytical method.) The lab reported all values falling below a Lower Detection Limit with a 'less than' symbol (<). In this dataset, all < symbols have been replaced with a negative value symbol (-). Thus, a value of -0.5 ppm Cd should be read as <0.5 ppm Cd. By contractual agreement with the laboratory, all samples with a concentration value that exceeded an analytical method's Upper Detection Limit were diluted and analyzed a second time to give a real value rather than a 'greater than' (>) value. For example, a zinc (Zn) value exceeding the ICPOES_MS-60 method’s Upper Detection Limit of >50,000 ppm Zn was reanalyzed in a diluted solution to return a value of 92,500 ppm Zn. However, on rare occasions a 'greater than' value was reported rather than a real value determined by reanalyzing a diluted solution. These are identified by a 1111 suffix. For example, a value reported only as >10000 ppm Ba is identified with the replaced value of 10000.1111 and a value reported only as >40.0% Si is identified with the replaced value of 40.01111 Logical_Consistency_Report: Each data record in this release represents a single sample with sample location information, sample/site descriptive information, and analytical data. Each record is identified by a unique laboratory-assigned ID (Lab_ID) and the original ID assigned to the sample when collected in the field (Field_ID) or pulled from the USGS National Geochemical Sample Archive. Since samples were submitted by multiple entities, there is no guarantee that the Field_ID is unique within the entire dataset. Each sample was submitted in a job (with a unique Job_ID) consisting of no more than 50 samples. As part of the quality control methodology, each job of samples includes a set of USGS in-house geologic reference samples (GRMs) submitted blind to the laboratory. Data records for USGS GRMs are identified by name in the QAQC field. Additionally, at least one sample within each job (Job_ID) was split and analyzed twice. The original sample is identified in the QAQC field as 'Original' and the second split is identified in this field as 'Duplicate'. Completeness_Report: This dataset contains all the sample descriptive information and geochemical data currently approved for release for geological samples submitted by Earth MRI projects. Updates will be released periodically as additional data are approved for release. Every sample was submitted, at a minimum, for total digestion analyses by the 60-element ICP-OES/ICP-MS method (C_ICPOES_MS-60). Most samples were also analyzed for major element oxides by WDXRF (C_WDXRF-MAJORS) and a subset were analyzed by additional methods. No sample was analyzed for every element or constituent by every available method and, therefore, each sample record has fields that have no data. Fields with no available data were left blank. Occasionally, in a job of samples submitted for a set requested analyses, a sample was submitted without enough mass to allow for all of the requested analyses to be completed. Fields where the sample was of insufficient size to be analyzed are also blank since no data were available. There are no analytical data fields with values of zero (0). Some software programs have been known to assign values of zero when importing data with blank fields. If the user encounters zero values in the data, it is recommended that they check the import parameters of their software to ensure that blank fields remain blank or are recognized as “Null” fields when imported into a different data format. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: 1) Coordinates: This data set contains geographic latitude-longitude coordinates determined by two very different methods. (i) Prior to the expanded civilian use (before ~2000) of the Global Positioning System (GPS), sample site coordinates were determined directly from hand-plotted sites on paper topographic quadrangle maps (usually 1:24,000 or 1:62,500 scale). Thus, the accuracy of these coordinates depends on the scale of the base map used and the accuracy at which the location was hand plotted on the map. The coordinate values were then determined either by using page-sized transparent 10-second grid overlays to estimate the position to the nearest second or by using a digitizing board. Coordinates determined by pre-GPS methods are generally accurate to approximately 2 seconds (60 meters) or better. Those originally reported in degrees, minutes, seconds format have been converted to decimal degree units and are usually reported to 3 or 4 decimal places. (ii) Once GPS units were in common use, coordinates were recorded digitally on site. GPS-derived coordinates are generally accurate to 5 meters or better and are usually reported as decimal degrees to 5 decimal places. All coordinates, as reported originally by the submitter or from compiled historic geochemical databases, are given in the Orig_Lat and Orig_Long fields and accompanied by the original datum used in the Orig_Datum field. Decimal degree coordinates were originally reported to 3, 4, or 5 decimal places. The implied accuracy of these values is approximately 100 meters for 0.001 degree, 10 meters for 0.0001 degree, and 1 meter for 0.00001 degree. 2) Datum and Earth Ellipsoid or Spheroid: The samples submitted were originally projected, located, and reported using a few different datums (Examples: NAD27, NAD83, WGS84). This original datum is recorded in the Orig_Datum field. Based on the value in the Orig_Datum field, all sample site coordinates were converted, when necessary, to the WGS84 datum and recorded in the Lat_WGS84 and Long_WGS84 fields. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: No formal positional accuracy tests were conducted. Sample depth values were accepted as provided by the sample submitter. No elevation information is included in this dataset. Lineage: Source_Information: Source_Citation: Citation_Information: Originator: Smith, Steven M.

They were also responsible for providing sample collection, sample description, and sample location information in a specified spreadsheet format when submitting samples to the USGS for analysis. Once received by the USGS, submitted samples were logged into the Laboratory Information Management System (LIMS), prepared, and sent to the laboratories for analysis. The accompanying sample descriptive and location data were collated and stored in a digital database table. Process_Date: 2020 Process_Step: Process_Description: Sample Preparation: Samples submitted to the USGS were prepared before sending them to the laboratories for analysis. Unless otherwise requested, samples were prepared using standard methodology. Rock samples were crushed and then a representative split of the material was ground in a shatterbox or ball mill using agate or aluminum corundum containers to -200 mesh (<75 microns) to ensure complete digestion of the sample when it was analyzed. Sediment samples were air-dried, sieved to a specified size fraction, and then ground in a vertical grinder with ceramic plates to -150 mesh (<100 microns). Soil samples were air-dried, disaggregated, sieved to a specified size fraction, and then ground in a vertical grinder with ceramic plates to -150 mesh. Previously-ground sample pulps pulled from the USGS National Geochemical Sample Archive were re-ground in a vertical grinder with ceramic plates to -150 mesh to ensure a uniform fineness of material. Process_Date: 2020 Process_Step: Process_Description: Sample Analysis and Methods: Every sample submitted to AGAT Laboratories, LTD (AGAT) was analyzed, at a minimum, by a total digestion, 60- or 61-element method using inductively coupled plasma-optical emission spectrometry (ICP-OES) and inductively coupled plasma-mass spectrometry (ICP-MS). Most samples were also analyzed for major element oxides by wavelength dispersive x-ray fluorescence spectrometry (WDXRF) and a subset were analyzed by additional methods. Descriptions of the methods used (and their method codes) are as follows: C_ICPOES_MS-60: Sixty or sixty-one elements (Al, Ca, Fe, K, Mg, P, S, Si, Ti, Ag, As, B, Ba, Be, Bi, Cd, Ce, Co, Cr, Cs, Cu, Dy, Er, Eu, Ga, Gd, Ge, Hf, Ho, In, La, Li, Lu, Mn, Mo, Nb, Nd, Ni, Pb, Pr, Rb, Re, Sb, Sc, Se, Sm, Sn, Sr, Ta, Tb, Te, Th, Tl, Tm, U, V, W, Y, Yb, Zn, Zr) are determined in rocks, minerals, sediments, and soils. Samples are fused at 750°C with sodium peroxide and the fusion cake dissolved in a dilute nitric acid. The resulting solution is analyzed by ICP-OES and ICP-MS. Data are deemed acceptable if recovery for all elements is ±15% at five times the Lower Detection Limit and the calculated Relative Standard Deviation (RSD) of duplicate samples is no greater than 15%. C_WDXRF-MAJORS: Major elements are determined by WDXRF and reported as major element oxides (SiO2, TiO2, Al2O3, Fe2O3, MnO, MgO, CaO, Na2O, K2O, P2O5, BaO, Cr2O3, SrO, V2O5). The sample is fused with lithium metaborate/lithium tetraborate flux and the resultant glass disk is introduced into the WDXRF and irradiated by an x-ray tube. The method also provides a gravimetric loss on ignition (LOI). Data are deemed acceptable when recovery of each major oxide is ±5% at five times the Lower Detection Limit and the calculated percent Relative Standard Deviation (RSD) of duplicate samples is no greater than 5%. C_FA_ICPMS-AU: Gold is determined by lead fusion and by ICP-OES and ICP-MS after collection by fire assay. The sample is mixed with fluxing agents to assist with melting and promote separation of waste (gangue) materials from the precious metals. After cooling, the gangue is separated and discarded as a glassy slag from the precious metal-containing lead button. This button is further heated on an absorbing magnesium oxide crucible to remove the lead and trace amounts of base metals. A small silver prill is left containing the precious metals. The silver prill is digested in aqua regia and then analyzed by ICP-OES and ICP-MS. Lower concentrations of Gold are measured by ICP-MS. Higher concentrations are measured by ICP-OES. Data are deemed acceptable when recovery of Gold is ±20% at five times the Lower Detection Limit and the calculated percent Relative Standard Deviation (RSD) of duplicate samples is no greater than 20%. C_FA_AU-PD-PT: Gold, Palladium, and Platinum are determined by lead fusion and by ICP-OES and ICP-MS after collection by fire assay. The sample is mixed with fluxing agents to assist with melting and promote separation of waste (gangue) materials from the precious metals. After cooling, the gangue is separated and discarded as a glassy slag from the precious metal-containing lead button. This button is further heated on an absorbing magnesium oxide crucible to remove the lead and trace amounts of base metals. A small silver prill is left containing the precious metals. The silver prill is digested in aqua regia then analyzed by ICP-OES and ICP-MS. Data are deemed acceptable if recovery of Gold, Palladium, and Platinum is ±20% at five times the Lower Detection Limit and the calculated percent Relative Standard Deviation (RSD) of duplicate samples is no greater than 20%. C_ISE-F: Fluoride is determined by ion-selective electrode (ISE) following a sodium hydroxide fusion. The sample is fused with a mixture of sodium hydroxide, potassium nitrate and silica to release fluoride ions from the sample matrix followed by dissolution of the fusion cake in dilute nitric acid. Prior to measuring the fluoride activity of the sample solution using an ion-selective electrode, an ammonium citrate solution is added to buffer the pH, maintain a constant ionic strength, and dissociate any metal ion-fluoride complexes. The fluoride concentration in the sample is then determined by interpolation from standard calibration curves. Data are deemed acceptable when recovery of Fluoride is ±20% at five times the Lower Detection Limit and the calculated percent Relative Standard Deviation (RSD) of duplicate samples is no greater than 20%. C_TOTAL-S: Total Sulfur is determined in geologic materials by combustion followed by infrared detection on LECO instrumentation. A weighed sample is mixed with an accelerator and heated via an induction furnace to oxidize sulfur to sulfur dioxide. Moisture and dust are removed, and the sulfur dioxide gas is then measured by a solid-state infrared detector. Data are deemed acceptable when recovery of Total Sulfur is ±15% at five times the Lower Detection Limit and the calculated percent Relative Standard Deviation (RSD) of duplicate samples is no greater than 15%. C_AQUA_REGIA: The sample is digested with aqua regia [nitric acid (HNO3) and hydrochloric acid (HCl)] and heated in a water bath for 1.5 hours at 85°C. The sample is then cooled to room temperature and analyzed by ICP-OES and ICP-MS for 51 elements (Al, Ca, Fe, K, Mg, Na, S, Ti, Ag, As, Au, B, Ba, Be, Bi, Cd, Ce, Co, Cr, Cs, Cu, Ga, Ge, Hf, Hg, In, La, Li, Mn, Mo, Nb, Ni, P, Pb, Rb, Re, Sb, Sc, Se, Sn, Sr, Ta, Te, Th, Tl, U, V, W, Y, Zn, Zr). Data are deemed acceptable when recovery for all 51 elements is ±15% at five times the Lower Detection Limit and the calculated Relative Standard Deviation (RSD) of duplicate samples is no greater than 15%. Process_Date: 2020 Process_Step: Process_Description: Quality Assurance/Quality Control and Data Approval: AGAT Laboratories, LTD is accredited to ISO/IEC 17025:2005 and certified to the ISO 9001:2008 standard. The laboratory’s quality control protocol is to insert a reagent blank and a reference sample material sample with every batch of 20 samples to measure the analytical accuracy. Duplicate samples were analyzed at the end of the sample set to measure analytical variance as well as sample variance. Data passing the laboratory’s quality control criteria were sent to the USGS and then imported into the Laboratory Information Management System (LIMS). All samples submitted to AGAT were accompanied with a set of USGS in-house geologic reference samples (GRMs) submitted blind to the laboratory at the rate of 10%. Using a program within the LIMS, a USGS Analytical Chemistry Quality Control Reviewer evaluated the data for the reference samples by comparing the “obtained” analytical value to the “expected” value for each element. The values must fall within the range of acceptance, which varies between ± 5% to ±20% depending on the analytical method. Analytical results for samples associated with the accepted quality control data were then released to the sample submitter and approved for release in this data product. Samples associated with rejected quality control data were re-analyzed by AGAT Laboratories until the resultant data were found to be “in control.” In addition to the GRMs, at least one randomly chosen sample per job was split and submitted blind to the laboratory as an analytical duplicate. Process_Date: 2020 Process_Step: Process_Description: Preparation and Compilation of Data for Release: Analytical data results for samples submitted by Earth MRI collaborative projects, analyzed by USGS contract laboratories, and approved for release by a USGS Analytical Chemistry Quality Control Reviewer were pulled from the Laboratory Information Management System (LIMS). These records were merged with sample descriptive and location information previously provided by collaborative entities when the samples were submitted for analysis. Original latitude-longitude coordinates were converted, when necessary, to the WGS84 datum and then recorded in the Lat_WGS84 and Long_WGS84 fields. Sample preparation information obtained from sample submittal requests and Sample Control was consolidated and summarized in the Sample_Prep field. Analytical methods used on the samples were summarized by laboratory code in the Analytic_Mthds field. Samples of USGS geologic reference materials and analytical duplicates were identified in the QAQC_Sample field. Earth MRI projects and affiliated agencies were identified and recorded in the PID, Proj_Name, and Affiliation fields. This initial version of the “Geochemical data generated by projects funded by the USGS Earth Mapping Resources Initiative” data release consists of 4,772 geochemical data records (including data for associated GRMs) that were approved for public release between April 14, 2020 and December 31, 2020.
