teeth, which additionally suggests that no elemental
incorporation has occurred to the submerged bones,
only leaching. Since these findings suggest that Mo,
Rb, and Zn were minimally or not affected by distil-
led water submersion, distilled water is likely a less
diagenetic environment for bog body preservation
than ethylene glycol.
Conclusion
Applying portable XRF's to the analysis of the Moora
Girl has provided much valuable Information about
the interactions between the bog environment and
the remains of this bog body, and verified that
elemental leaching occurred to the specific remains
that underwent post-discovery preservative treat-
ment. Because diagenesis may have occurred in this
raised bog body, we conclude that one cannot apply
data involving Sr concentrations to geographic origin
and migration studies.
When determining whether post-depositional
diagenetic alteration has altered the remains of
Moora Girl, data collected from tooth, bone, and
soil Sr levels in 2009 and 2011 supported that it
had occurred, but such findings were not supported
with the data from 2010. The significant difference
between bone and soil Sr levels in 2010 may be due
to the fact that the bones were only scanned once
that year. This would have narrowed their elemental
concentration ränge making differences between the
compared groups much more significant. In addi-
tion, although the findings in 2010 were statistically
significant, the practicality of their significance is
not germane to the hypotheses investigated for this
research. Since soil Sr levels vary in concentrations
throughout the raised bog environment, Sr concen-
tration ranges are used to compare Sr for bog body
bone and/or teeth to burial environment soil. As
a result, applying Statistical analysis that directly
compares tooth, and/or bone, and soil levels for
bog bodies whose body levels fall within the soil
ränge they are being compared to, does not provide
evidence to accept or reject the corresponding hypo-
thesis. Rather, comparing the soil Sr ranges to that
of the bone and/or teeth can provide the proper
information on whether or not there is correlation
among these variables. Using the graphs and boxplots
