    Description
      Abstract: This digital dataset contains new geological data and information generated by the Alberta Geological Survey (AGS) on the Canadian Shield in northeastern Alberta. AGS crews conducted fieldwork in the Leland Lakes and Andrew Lake area for a total of four weeks in the summer of 2023, recording geological observations and measurements for 394 field stations. This included descriptions of lithology, mineralogy, and texture, along with magnetic susceptibility, gamma-ray spectrometer, and structural orientation measurements, and the collection of rock samples for additional analysis. Of the 544 samples collected, 523 were prepared and submitted for whole-rock lithogeochemical analysis to support the evaluation of critical mineral potential in the area.

This work was completed under the Mineral Grant provided by the Government of Alberta June 22, 2021.
      Purpose: To provide new geological data generated by the AGS from fieldwork in the summer of 2023 on the Canadian Shield in northeastern Alberta, including field observations and whole-rock lithogeochemistry from samples collected.

  Attribute_Accuracy
    Attribute_Accuracy_Report: Station Observations

Many of the classifications provided in the Station Observations dataset (e.g., lithology, rock type, mineralogy) can be influenced by the geologist's background and experience, the quality and extent of outcrop exposures, the weather conditions, and the limited time available to spend at the outcrop. Field teams made an effort to review samples and visit select outcrops together to maintain consistency. Classifications represent field observations, as recorded during fieldwork; they have not been reconciled with subsequent analytical data generated (e.g., petrographic analysis, whole-rock lithogeochemistry).

Structural measurements included in Station Observations used the right-hand rule.  These measurements were collected with Brunton transit, or Brunton TruArc 15 compasses.

Radiometric assays and gamma-radiation measurements in Station Observations used two newly purchased and calibrated Radiation Solutions Inc.'s RS-230 BGO Super-SPEC handheld gamma-ray spectrometers.

Magnetic susceptibility measurements (MS_min, MS_avg, MS_max) were generated with a ZH Instruments' SM 30 handheld magnetic susceptibility meter. This instrument was not calibrated. The magnetic susceptibility values reported are not based on a consistent number of readings. The reported values represent the average of measurements collected, which ranged from two up to ten. These values were gathered strictly to help highlight differences between visually similar lithologies.

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Whole-Rock Lithogeochemistry

The accuracy and 95.5% confidence-level precision of the whole-rock lithogeochemical data were estimated in terms of the average percentage recovery (APR) and relative standard deviation (2RSD) values, respectively. However, the 2RSD values include propagated errors of the expected concentrations in the reference materials. Therefore, the 2RSD values also represent uncertainties in the accuracy estimates.

Two certified reference materials (CRMs) were submitted to the lab at regular intervals of approximately 1 CRM for every 20 samples. The two CRMs selected for this project were OREAS 30a (olivine tholeiitic basalt), and OREAS 20a (barren I-type hornblende-bearing granodiorite).

The average APR of the whole-rock geochemical determinations for OREAS 20a is 99.9%, and 100.0% for OREAS 30a. Accuracy results for individual elements are listed in the "Shield_Whole-Rock_Lithogeochemistry_Detection_Limits" file.

The average 2RSD of the whole-rock geochemical determinations for OREAS 20a is 10.5%, and 12.1% for OREAS 30a. Precision results for individual elements are listed in the “Shield_Whole-Rock_Lithogeochemistry_Detection_Limits” file.

Where elements are reported from the laboratory, but certified values are not reported for the CRM, both APR and 2RSD values are listed as -9999.

Non-analysis fields with the value -9999 are null.
  Logical_Consistency_Report: Station Observations

Locations and IDs were checked for uniqueness; no duplicates exist in this data.

The number of geological features observed and recorded at individual stations was controlled by several factors, including but not limited to time constraints, weather conditions, and outcrop exposure quality. Where features were not measured or not observed, a value of -9999 is recorded.

Field traverse teams varied from day to day; however, the traverse leaders were consistent for the duration of field work in 2023. Russell Hartlaub was given a 1000-series code for the collection of station and sample data (e.g., LL-23-1000 or AL-23-1000), and Nicholas Montenegro was given a 2000-series code for the collection of station and sample data (e.g., LL-23-2000 or AL-23-2000). Field assistants for each traverse leader varied, with AGS staff cycling in and out of the field. The traverse leader was responsible for maintaining consistency in geological observations and data collection.

The generalized rock class (Rock_cls1 and Rock_cls2) reported in this dataset was used inconsistently throughout the course of field work. This field was intended to capture the hierarchical framework of lithologies observed (e.g., granitoid, gneiss, migmatite, etc.) to quickly group and filter similar geological observations. At times this field was used properly; however, it was also used as a modifier for the lithology observed (e.g., mylonitic granite), and as a reference to protolith (e.g., granite protolith of an orthogneiss).

The lithology (Lith1 and Lith2) attributes contain lithology names based solely on field observations by the field geologists. These classifications have not been altered to reflect additional information from subsequent whole-rock lithogeochemistry or petrographic analysis. 

Limited data entry review was completed while in the field. Tablet data was reviewed during preparation for publication. Errors may exist within this dataset (e.g., spelling errors, misused words owing to auto-correct features on the tablet, limited punctuation, etc.).

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Whole-Rock Lithogeochemistry

All Sample IDs were checked for uniqueness; no duplicates exist. Spatial coordinates for samples were extracted from the respective station location, which represents a single point on exposed outcrop. However, it was common practice to collect samples from anywhere on the outcrop where representative grab samples could be extracted with a hammer. This means that the true sample location could extend several metres (up to ~10 m) away from the station coordinates.

Observed lithology (Obs_litho), sample type (Smpl_type), and sample note (Smpl_notes) information included with the whole-rock lithogeochemistry results were extracted from the station observation dataset. Both observed lithology and sample type classifications were populated after a complete review of all station information recorded, including notes related to the station, lithology notes, and sample notes.

Null values exist where analytical re-runs only reviewed parts of the analytical packages requested, these values have been replaced with -9999. Values that include a less-than sign (i.e., <) indicate measurements below the limit of detection (LOD), and values that include a greater-than sign (i.e., >) indicate measurements above the LOD. Minimum and maximum detection limits for each analyte in the dataset are listed in the "Alberta_Shield_2023_Geochemistry_Detection_Limits" file.
  Completeness_Report: Station Observations

Four samples were excluded from the final dataset. Two samples were excluded from the final list due to recording the same ID for two distinctly different samples with limited supporting field notes. Without enough context to resolve the ID duplication, both samples were removed from the collection. Two other samples were excluded from the final list due to a recorded station ID that did not exist in the tablets and a lack of supporting field notes. Without context to confirm location and why they were collected (e.g., whole-rock lithogeochemistry or petrographic analysis) both samples were also excluded.

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Whole-Rock Lithogeochemistry

Two samples were excluded from the final dataset. These are the two samples that were also removed from the station observations dataset due to a recorded station ID that did not exist in the tablets or backup field notes. Given the uncertainty regarding where and why they were collected, the results were removed.
  Positional_Accuracy
    Horizontal_Positional_Accuracy
   Horizontal_Positional_Accuracy_Report: Station GPS locations were generated directly from the tablets used by the AGS (Apple iPad Pro, 4th generation with Wi-Fi + Cellular that includes GPS/GNSS).  Neither accuracy nor precision metrics were collected with the coordinates generated. Horizontal error estimates are not provided by Apple for iPad Pro tablets.  Although several factors control GPS/GNSS accuracy (e.g., satellite geometry, signal blockage, atmospheric conditions, receiver design), accuracy is typically within 5 m under open sky (https://www.gps.gov/systems/gps/performance/accuracy/).  Owing to the uncertainty of controlling factors listed above, coordinates provided are estimated to be +/- 10 m.

  Lineage
    Process_Step
   Process_Description: Station Observations

The data included in this publication were generated from fieldwork on the Canadian Shield in northeastern Alberta by AGS staff in the summer of 2023. Staff visited 394 stations where observations (e.g., lithology, mineralogy, texture, structures, sample details) and measurements (e.g., gamma-ray spectra, magnetic susceptibility, structure orientation) were captured in tablets.

Data collection was completed using two tablets (Apple iPad Pro, 4th generation) with OPENGIS.ch's QField application. Data entry forms were prepared by AGS staff prior to fieldwork to assist in capturing relevant details within a structured format.

Individual stations represent outcrop locations where field teams stopped to record relevant geological information. Station locations are recorded as a single point location, but it should be noted that observations are made at the outcrop scale that can extend several metres (up to ~10 m) from the recorded coordinates.
   Process_Date: 2023
      Process_Step
    Process_Description: Geochemistry

The data included in this publication were generated from fieldwork on the Canadian Shield in northeastern Alberta by AGS staff in the summer of 2023. A total of 544 samples were collected in the field, of which 523 samples were submitted for whole-rock major and trace element determinations. For internal data-quality control an additional 28 certified reference material samples (i.e., OREAS 20a, OREAS 30a) were included for analysis, inserted as every 20th sample. Results for a total of 556 samples are reported, including 28 certified reference materials, and 5 analytical reruns of select certified reference materials.

Analysis was conducted by Activation Laboratories Ltd., using inductively coupled plasma optical emission spectrometry (ICP-OES) or mass spectrometry (ICP-MS). The specific Activation Laboratories Ltd. analytical methods were:

- Code 4Litho-Research: samples are subject to lithium metaborate/lithium tetraborate fusion within disposable graphite crucibles, the resulting molten bead is digested in a solution of 5% nitric acid and mixed until completely dissolved (~30 minutes). ICP-MS/OES is used to quantify various elements in resulting solution (https://actlabs.com/geochemistry/lithogeochemistry-and-whole-rock-analysis/lithogeochemistry/).

- Code 4B1: samples are digested with four acids beginning with hydrofluoric, followed by a mixture of nitric and perchloric acids, heated using precise programmer-controlled heating in several ramping and holding cycles which takes samples to dryness. After dryness is attained, samples are brought back into solution using hydrochloric acid. ICP-OES is used to quantify base metals in resulting solution (https://actlabs.com/geochemistry/lithogeochemistry-and-whole-rock-analysis/lithogeochemistry/).

- Code UT7 (lithium only): samples are subject to sodium peroxide fusion within zirconium crucibles, the resulting molten bead is acidified with concentrated nitric and hydrochloric acids. ICP-OES is used to quantify lithium in resulting solution (https://actlabs.com/geochemistry/lithogeochemistry-and-whole-rock-analysis/peroxide-total-fusion/).
