Fraccionación de los elementos traza durante la fusión parcial incongruente de metapelitas
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 solid is known, or the expressions obtained by Hertogen and...

| Palabra clave: | Anatexis Incongruent melting Trace element Metapelites |
| Sumario: | 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 solid 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 α+ß+γ=ð+e+Liq |
