Fig. 9

Density values distributions for peridotites and serpentinites (see Fig. 7 caption for explanations). For these rock types only outcrop data were available and only in limited numbers. Both peridotites and serpentinites show distinct peaks in their distributions. The large standard deviation corresponds with the nature of the two rock types, serpentinites being the product of alteration of peridotites rather than to data variations due to measurement differences or uncertainties (see text)
