• Resumen

  • During anatexis of metapelites, the trace element fractionation can't be modelled by the mathematical expressions derived by Shaw (1970). In this case, the equations of Hanson (1978) should be used, when the mineralogy of residual so/id is known, or the expressions obtained by Hertogen and Gijbels (1976), when the composition of the initial solid is known.

    In this paper, the mathematical expressions presented by these last authors to treat incongruent melting processes, are extended to a more general case when the breakdown of one phase (a) takes the form a+/J+y=o+E+Liq.
