A firefighter covered in a little soot and sweat isn't anything to sneeze at!They are thus, theoretically, not particularly susceptible to partitioning during melting of silicate rocks.Fractional crystallisation of felsic minerals changes the Sm/Nd ratio of the resultant materials.Samarium is accommodated more easily into mafic minerals, so a mafic rock which crystallises mafic minerals will concentrate neodymium in the melt phase faster relative to samarium.Thus, as a melt undergoes fractional crystallization from a mafic to a more felsic composition, the abundance of Sm and Nd changes, as does the ratio between Sm and Nd.
