Conceptual consistency:
Measure description:
The analytical data for approximately 17% of the samples were checked against the original laboratory
reports to check for consistency and no errors were detected. One repeat analysis is present (5602R), so
the total number of analytical records (124) exceeds the total number of samples by one. The repeat
analysis was performed to more accurately determine the amount of phosphorus (P) and uranium (U) in
sample 5602 by having the analytical laboratory insert high-P and high-U standards in the analytical
batch. Included with the analytical results are average per cent recovery values, a measure of accuracy,
based upon eight samples of CANMET certified reference material (standard) SY-4 (cf. Ziegler and Combs,
1997). Samples of SY-4 were weighted (12 to 25 g) and placed in vials by the AGS and included in batches
of samples prior to shipment to the commercial analytical laboratory. The percentage recovery for each
standard measurement is defined by the following equation: Percentage recovery = 100 x CM/CA where CM =
the measured concentration of the standard sample CA = the actual concentration of the standard sample
Percentage recovery values near 100% indicate a high degree of accuracy. Included with the analytical
results are average relative per cent difference (RPD) values, a measure of precision, based upon up to
ten duplicate sample pairs (cf. Ziegler and Combs, 1997; Zimmerman et al., 2001). The pairs include
duplicates prepared before pulverization by AGS and duplicates prepared after pulverization by the
analytical laboratory. The RPD for a set of duplicate pair results is defined by the following equation:
RPD = 100 x [absolute value (C1 - C2)]/ CX where RPD = relative percentage difference C1 - C2 = the
difference between the two concentrations CX = mean of the two results Low RPD values for the duplicate
pairs indicate a high level of analytical precision. References Ziegler, A.C. and Combs, L.J. (1997):

Description:
The rock samples were collected from 2001 to 2005 (a) in the field by AGS staff, (b) from core stored
at the Alberta Geological Survey (AGS) Mineral Core Research Facility (MCRF) in Edmonton, Alberta,
and (c) from core stored at the Alberta Energy and Utilities Board (EUB) Core Research Centre in
Calgary, Alberta. All analytical work, including sample preparation, was performed by Acme
Analytical Laboratories Ltd. (Acme) of Vancouver, B.C. The method descriptions listed below were
provided by Acme.
Sample preparation: Samples were crushed and then pulverized using mild steel to <150 mesh (<0.100 mm).
Four-Acid (HF-HNO3-HClO4-HCl) ICP-AES/MS Multi-Element Analyses (Acme Method 1EX): Acme completed
four-acid digestion of the samples followed by inductively coupled plasma atomic emission
spectrometry (ICP-AES) and inductively coupled plasma mass spectrometry (ICP-MS) analyses.
Pulverized splits of 0.25 g were weighed into Teflon test tubes. A 10 mL aliquot of the acid
solution (2:2:1:1 H2O-HF-HClO4-HNO3) was added, heated until fuming on a hot plate and taken to
dryness. A 7.5 mL aliquot of 50% HCl was added to the residue and heated in a hot water bath (~95
degrees C) for 30 minutes. After cooling, the solutions were transferred to polypropylene test tubes
and made to a 10 mL volume with 5% HCl. Solutions were analyzed by ICP-AES (Jarrel Ash AtomComp 800
ICP emission spectrometer) and ICP-MS (Perkin Elmer Elan 6000 ICP mass spectrometer). Elements with
high concentrations, including major elements, are reported by ICP-AES, whereas elements with low
concentrations (e.g., Be, Hf and Ta) are reported by ICP-MS. Elements that can span a broad range of
concentrations (e.g., Cu, Pb and Zn) may be reported by either ICP-MS (low concentrations) or
ICP-AES (high concentrations).
Aqua Regia ICP-AES/MS Multi-Element Analyses (Acme Method 1F): Analyses were performed using 1 g to 15
g of material following Acme's 1F analytical procedure. The Acme version of aqua regia (equal
proportions of HCl, HNO3 and demineralized H2O) was added to each sample in a ratio of 6 mL of aqua
regia to 1 g of sample. Samples were digested for one hour in a hot water bath (90-95 degrees C)
then diluted to a 20:1 mL/g final ratio. All sample solutions were analyzed by both ICP-AES (Jarrel
Ash AtomComp 800 ICP emission spectrometer) and ICP-MS (Perkin Elmer Elan 6000 ICP mass
spectrometer). ICP-AES values may be reported for several elements if concentrations exceeded
laboratory-determined crossover values; otherwise, ICP-MS results are reported.
Sulphate Sulphur (Acme Method 2A): Sample splits (0.1 g) in Leco crucibles were ignited at 800 degrees
C for one hour to decompose sulphides and drive off the sulphur as SO2. Upon cooling the samples
were analyzed in a Leco C244 Carbon-Sulphur analyzer. The sulphur determined is attributed to the
presence of sulphur as sulphate.
Carbonate Carbon as CO2 (Acme Method 2A): For each sample a pulp split of 0.2 g was weighed into 500
ml polypropylene bottle. A 34 mL aliquot of water was added. A test tube containing 6 mL of
concentrated ACS grade HCLO4 was delicately placed inside the bottle. A cap fitted with two
stopcocks was tightly screwed on. The bottle was tilted to allow the acid, water and sample to mix.
The bottle was placed in a hot water bath (70 degrees C) for 30 minutes to help evolve CO2 into the
gas phase. For sample analysis, the bottle was attached to a Leco C244 Carbon-Sulphur analyzer via
the stopcocks. The CO2 was swept into the analyzer with an O2 carrier gas. The instrument determines
and reports the carbon content from which the CO2 content is calculated.
Graphitic Carbon (Acme Method 2A): The graphite-carbon content was determined by first removing the
organic and carbonate-carbon fractions. Sample splits (0.1 g) were placed in Leco crucibles. Organic
carbon was removed by igniting the samples for one hour at 600 degrees C. After cooling, the
residues were leached with 15% HCl for one hour to remove the carbonate fraction. The residues were
then analyzed using a Leco C244 Carbon-Sulphur analyzer. Induction flux was added to the residue and
the samples were ignited at >1650 degrees C in an induction furnace. A carrier gas was used to sweep
up released carbon to be measured by adsorption in an infrared spectrometric cell. Results are
attributed to the presence of carbon as graphite.
Organic Carbon (Acme Method 2A): After determination of the other forms of carbon, the organic carbon
content is calculated as organic carbon = total carbon - graphitic carbon - carbonate carbon.
Fusion ICP-AES Multi-Element Analyses (Acme Method 4A): Acme completed fusion digestion of the samples
followed by inductively coupled plasma atomic emission spectrometry (ICP-AES) analyses. For each
sample a 0.2 g sample aliquot was weighted into a graphite crucible and mixed with 1.5 g of LiBO2
flux. The flux/sample charge was heated in a muffle furnace for 15 minutes at 1050 degrees C. The
molten mixture was removed and immediately poured into 100 mL of 5% HNO3 (ACS-grade nitric acid in
demineralized water). The solution was shaken for two hours and then an aliquot was poured into a
polypropylene test tube. Sample solutions were aspirated into an ICP emission spectrometer (Jarrel
Ash Atomcomp Model 975). Determinations were made for SiO2, Al2O3, Fe2O3 (total Fe), MgO, CaO, Na2O,
K2O, P2O5, MnO, Cr2O3, Ba, Ni, Sc and LOI. To determine Loss on Ignition (LOI), a 1 g sample split
was ignited for 90 minutes at 950 degrees C, cooled in a desiccator and then weighted with the
difference expressed as per cent Loss on Ignition. Total C and total S were determined on a 0.1 g
sample split using a Leco C244 Carbon-Sulphur analyzer.
Fusion ICP-MS Multi-Element Analyses (Acme Method 4B): Acme completed fusion digestion of the samples
followed by inductively coupled plasma mass spectrometry (ICP-MS) analyses. A 0.2 g sample aliquot
was weighted into a graphite crucible and mixed with 1.5 g of LiBO2 flux. The flux/sample charge was
heated in a muffle furnace for 15 minutes at 1050 degrees C. The molten mixture was removed and
immediately poured into 100 mL of 5% HNO3 (ACS-grade nitric acid in demineralized water). The
solution was shaken for two hours, and then an aliquot was poured into a polypropylene test tube.
Sample solutions were aspirated into an ICP mass spectrometer (Perkin-Elmer Elan 6000).
