Elemental data

Probability Plots. To distinguish between background distributions and human activity, trace element data were probability plotted using the method of Velz (10), The plots produce two separate trend lines, the intersection of which distinguishes natural from anthropogenic concentrations. Figure 10 is an illustration of the resulting plots for zinc (38),... 

None of the elemental data show any correlation with collagen yield. When compared to yield, the correlation coefficients are non-significant for C N (r = 0.4), %C (r = 0.4) and %N (r = 0.2). All samples with low elemental values are from layers of bone that showed poor histological preservation. While low values tend to come from bone with poor histological preservation, many samples from bone of equally poor preservation produced acceptable values. Lipid removal generally improved both the yield characteristics and elemental values. 

It should be pointed out that no other analytical technique has the capability to provide multi-element data non-destructively, often with good detection limits and...

Analysis by the Detection of X-rays or y rays. EPMA is a fully qualitative and quantitative method of non-destructive analysis of micrometre-sized volumes at the surface of materials, with sensitivity at the level of ppm. All elements from Be to U can be analysed, either in the form of point analysis, from line scans and also as X-ray distribution maps. Current software allows the combination of elemental data in the latter, so that, for example, the digital data for those elements that corresponds to a selected phase will produce an X-ray map of the distribution of that phase in a given microstructure.
