Figure 8
Comparison of frequency histograms normalized respect to the total number of measurements (see text for a detailed explanations) for the three carbonates litho-stratigraphic units. (A) Normalized frequency histograms of Calcare Massiccio (Blue), Maiolica (Green) and Calcareous Scaglia (Orange) measured in the Highly-Deformed Apennine Ridge (HDAR). (B) Normalized frequency histograms of Calcare Massiccio (Cyan), Maiolica (light Green) and Calcareous Scaglia (Yellow) measured in the nearly-Undeformed Adriatic Foreland (NUAF). For clarity, we normalized the frequency values so that the sum of the reported frequencies for each lithostratigraphic unit pertaining to each of the structural domain, is equal to 100. In other words, we plot the data so that a value of 10 in the y axis and 6.0 km/s in the x axis in the curves in Fig. 8 means that the 10% of the measurements recorded 6.0 km/s.
