Heterogeneities thermal anomalies

We now turn briefly to examples of the thermal anomalies in heterogeneous systems. Shamsul Huq and Lodhi (136) recently determined the distribution of benzoic acid between benzene and water as a function of temperature (Figure 7). The upper set of points refers to the observed distribution coefficient based on the monomer (in the benzene phase). The data points are those obtained by Shamsul Huq and Lodhi straight-line segments have been drawn in by the present author. Obviously, little significance can be attached to a 4 curve such as this which is based on only two points for the higher temperature range, yet, it is... 

The principal observation behind the Helffrich and Wood (2001) model of the mantle is that the scattering of seismic waves in the lower mantle indicates that small heterogeneities are present, mostly about 4 km in size. As with all seismic methods the physical cause of the seismic scattering anomalies could theoretically be either thermal or compositional in origin. Helffrich and Wood (2001)...
