    Description:

      Abstract: This digital data release presents laboratory measured thermal conductivity, thermal diffusivity, and radiogenic heat production data for core samples from the Precambrian crystalline basement in Alberta. Thermal conductivity measurements were obtained for 42 Precambrian basement samples using two methods: the steady-state divided bar method and the transient optical scanning (thermal conductivity scanner) method.

Thermal conductivity and diffusivity measurements for some samples were conducted under both dry and water-saturated conditions and in multiple orientations to assess directional anisotropy. Directional thermal conductivity was measured using both the steady-state divided bar method and the transient optical scanning method, depending on samples conditions. Thermal diffusivity was measured for 18 samples analyzed using the optical scanning method. The divided bar method was used to measure thermal conductivity only under water-saturated conditions and does not provide thermal diffusivity measurements or thermal conductivity values under dry conditions.

Radiogenic heat production for 90 samples was estimated using standard empirical formulations based on uranium, thorium, and potassium concentrations derived from whole-rock geochemical analyses, and reflects substantial variability associated with basement lithology and tectonic domain.

Together, these measurements provide a comprehensive dataset capturing the effects of anisotropy, fluid saturation, and compositional variability on subsurface thermal properties. The dataset supports geothermal resource assessment, heat flow modelling, and regional to crustal scale thermal structure analyses in Alberta.

This work was completed under the Mineral Grant provided by the Government of Alberta, dated June 22, 2021.

      Purpose: To provide reliable measurements of thermal conductivity and thermal diffusivity, together with derived radiogenic heat production, for diverse rock types from Alberta’s Precambrian basement.

Data_Quality_Information:

  Attribute_Accuracy:

    Attribute_Accuracy_Report: All attributes in this dataset are as received from the tests done at the labs or derived through subsequent interpretation. Measurements for thermal conductivity and thermal diffusivity and derived radiogenic heat production recorded with two decimals.

  Logical_Consistency_Report: The spatial locations of all samples are unique. In some cases, several samples were taken from drillcore from the same well, but at different depths, resulting in duplication of unique well identifiers (UWI) and geographic coordinates (longitude, latitude). Laboratory measurements of thermal conductivity and thermal diffusivity were obtained using steady-state and transient methods to characterize basement rocks from Alberta. Existing thermal property datasets for deep crystalline rocks are sparse. Radiogenic heat production estimates derived from whole rock U–Th–K concentrations mostly show lithology and tectonic domain dependent variability consistent with petrographic observations and regional geological frameworks.

  Completeness_Report: Many basement-penetrating wells did not recover core, and recovered material was often too altered, fractured, or incomplete for sample-plug preparation. A larger proportion of available samples came from shallower intersections (<2 km) in the northeastern and north-central regions, where drilling activity has historically been more frequent. Fewer samples were recovered from deeper intersections, limiting direct representation of higher-temperature basement conditions in the dataset. Sample selection was therefore constrained primarily by availability of specimens and did not allow for systematic coverage of specific tectonic domains. All data records with sufficient information were selected from described sources. Null values are reported as -9999.

  Positional_Accuracy:

    Horizontal_Positional_Accuracy:

   Horizontal_Positional_Accuracy_Report: The locations of the oil and gas wells may be accurate to within millimetres depending on surveying standards at the time of drilling.

    Vertical_Positional_Accuracy:

   Vertical_Positional_Accuracy_Report: Samples were collected based on core depth relative to the well’s kelly bushing. Core depth was referenced to the depth interval recorded on the core box.

    Process_Step:

   Process_Description: Sampling:

Core samples were obtained from boreholes that penetrated the Precambrian basement in Alberta. While the Western Canada Sedimentary Basin (WCSB) hosts hundreds of thousands of wells, only a few hundred extend into the crystalline basement. Sample selection was therefore constrained primarily by availability of specimens and did not allow for systematic coverage of specific tectonic domains. The depth to the top of the basement in Alberta varies significantly from outcrop at surface in the far northeast (Canadian Shield) to depths exceeding 4 km near the Cordilleran deformation front in the southwest. A larger proportion of available samples came from shallower intersections (<2 km) in the northeasteastern and north-central regions, where drilling activity has historically been more frequent. Fewer samples were recovered from deeper intersections, limiting direct representation of higher-temperature basement conditions in the dataset. Sample locations and slabs were selected by the authors of this publication. Cylindrical core plugs (1 inch or 1.5 inches in diameter) were cut from drillcore by AGS staff at the AER’s Core Research Centre, Calgary.

Thermophysical Properties:

Thermal conductivity (TC) of the rock samples was determined using two techniques: the steady-state divided bar method and the optical scanning method. Thermal diffusivity was measured using the optical scanning and transient plane source methods.

Divided Bar Method:

The divided bar method, applied at the University of North Dakota (UND), USA, was used to obtain directional steady-state thermal conductivity measurements. Samples were prepared as cubes or prisms with polished faces (<0.02 mm deviation). Prior to measurement, samples were dried, weighed, put under vaccuum, saturated, and weighed again to determine porosity. Thermal conductivity was measured along three orthogonal axes using copper disks, with petroleum jelly applied to improve thermal contact. All samples were fully saturated during measurement. Saturation was achieved by placing samples under vacuum for 24 hours, followed by submersion in water for an additional 24 hours; samples remained submerged until measurements were completed. Porosity was calculated from sample dimensions and mass measurements taken before and after saturation, with the mass increase used to compute pore water volume. During thermal conductivity measurements, samples were subjected to an axial pressure of 700 to 1000 psi.

Optical Scanning Method (TCS):

The optical scanning method (thermal conductivity scanner, TCS), at the German Research Centre for Geosciences (GFZ) was applied to samples under both dry and water-saturated conditions. This technique employs a moving linear heat source coupled with infrared sensors to record surface temperature variations, generating continuous high-resolution profiles of thermal conductivity and thermal diffusivity along the scanned surface. Prior to measurement, samples were oven dried at 60°C and subsequently vacuum-saturated for saturated measurements.

Measurements were repeated a minimum of three times on different sample surfaces or orientations. Calibration was performed using reference materials with known thermal conductivity at both ends of each scan line. Anisotropy was estimated from the ratio of maximum to minimum conductivity values measured across different directions. The spatial resolution of the scans is approximately 1 mm, and measurement uncertainty is estimated to be within ±5%.

Radiogenic Heat Production:

Radiogenic heat production (RHP) was estimated using standard empirical formulations, (e.g., Bucker and Rybach, 1996; Majorowicz et al., 2014), based on uranium, thorium, and potassium concentrations derived from whole-rock geochemical analyses published in AGS Digital Data 2006-0001.

   Process_Date: 2025

  Data_Quality_Information: Thermal property measurements were conducted following established laboratory best practices to ensure accuracy, repeatability, and internal consistency across methods.

Divided bar method:

Samples were prepared with polished, parallel faces to ensure optimal thermal contact. Contact resistance was minimized using interface coupling material (petroleum jelly), and an axial load of approximately 700–1000 psi was applied during measurements. Samples were allowed to reach thermal equilibrium prior to data acquisition, and thermal conductivity values were calculated from the average of 100 stabilized readings per measurement orientation. Instrument calibration was verified using certified reference materials, and results were evaluated to identify potential outliers.

Optical scanning method (thermal conductivity scanner, TCS):

Measurements were performed under both dry and water-saturated conditions, with a minimum of three scan lines acquired per sample on different surfaces or orientations where possible. Calibration against certified reference materials was performed for each scan line. Measurement accuracy is within ±5%, with reproducibility typically better than ±1%.

Despite the implementation of rigorous QA/QC procedures, several limitations should be considered when interpreting the dataset:

• Some foliated samples developed fractures during preparation or testing and were excluded from anisotropy analyses where necessary.

• Measurement orientations (A, B, and C) used for directional anisotropy analyses are relative and are not geographically referenced.

• Laboratory vacuum saturation approximates pore fluid effects but does not fully replicate in situ pressure, temperature, or fluid chemistry conditions.

• In very low porosity crystalline rocks, Archimedes based density and porosity measurements may be subject to increased uncertainty, as small mass differences associated with pore water saturation may approach the resolution limits of laboratory balances.

• Measurements represent core scale properties and may not fully capture larger scale lithologic or structural heterogeneity.

• Mineralogical bounds derived from X-ray diffraction (XRD) analyses provide theoretical constraints on thermal properties but do not explicitly account for microstructural effects.
