           Fig. 4-12. Log-log plots of relation between areas bounded by concentration contours A(•v) and
           uni-element concentration values, Aroroy district (Philippines). Solid lines are obtained by least
           squares fitting through linear parts of the plots. Dots at breaks in slopes of the lines represent
           threshold concentrations (v t ).  Lines to the left of any threshold follow a power-law relation
           represented by equation (4.6), whereas lines to the right of rightmost thresholds follow a power-
           law relation represented by equation (4.7).


           equivalents of the two lower thresholds based on the discrete geochemical surface. The
           differences in the  results  obtained are plausibly  due to the  fact that the continuous
           geochemical surfaces are smoother than the discrete geochemical surfaces.
