X -ray Diffraction:
X -ray Diffraction (XRD) analysis detects only crystalline materials, which may or may not
represent all components of the sample. Amorphous constituents cannot be identified or
accounted for in the XRD analysis, although high proportions may produce significant
background noise. This may potentially mask crystalline components. Detection limits
of crystalline materials generally range from 5 to 15%, depending on background noise
and sample quality. The results are semi - quantitative (± 5 to 10 %, but possibly up to
20% depending on the crystallinity of the sample). To ensure consistent accurate XRD
results a quartz standard sample is analyzed on a weekly basis. It is then compared to a
standard quartz XRD pattern in order to identify possible deviations in peak
intensities /positions.
Sample Preparation:
Samples submitted for whole rock and clay - fraction X -ray diffraction (XRD) mineral
analyses are first cleaned of obvious drilling contaminants and then disaggregated in a
mortar and pestle. Approximately 5 grams of each sample are mixed with isopropyl
alcohol and pulverized using a McCrone micronising mill. The resultant powders are
dried, disaggregated, and packed into stainless steel sample holders to produce random
whole -rock mounts. A separate split of each sample is dispersed in a dilute sodium
hexa -meta phosphate solution using a sonic probe. The suspensions are then
centrifugally size fractioned to isolate clay -size (< 4µm ESD) materials for a separate

clay- tract mount. The suspensions are then vacuum - deposited on a silver membrane
filters to produce orientated clay mineral aggregates. Membrane mounts are attached to
stainless steel slugs and exposed to ethylene glycol vapor for a minimum of 24 hours.
Analytical Procedures:
XRD analyses of the samples are performed using a Scintag automated powder
diffractometer equipped with a copper source and a solid state Peltier detector. The
whole rock samples are analyzed over an angular range or 2 -60 degrees 29 at a scan
rate of one degree /minute. The glycol- solvated clay- fraction mounts are analyzed over
an angular range of 2 -50 degrees 29 at a rate of 1.5 degrees /minute.
Semi - quantitative determinations of whole rock and phyllosilicate mineral amounts are
done using integrated peak areas (derived from peak - decomposition / profile- fitting
methods) and empirical reference intensity ratio (RIR) factors determined specifically for
the diffractometer used in the data collection.
