A series of geochemical maps for six elements are presented here, each accompanied by a downloadable file with summary interpretation data. If you are interested in additional elements please contact us through the contact page or by emailing argyraki@geol.uoa.gr.
Class intervals on the geochemical maps were defined by natural breaks in the histograms of the original data, and elemental concentrations were plotted as circles with size increasing as a function of concentration. The interpolated surfaces using the Inverse Distance Weighting method (IDW) with a power of 2 were added in the background for better visual inspection of the spatial trends (red being higher and blue being lower).
It must be noted that interpolated maps must be used with caution due to the variability between the sampling locations.
