Resumen de Cálculo de los parámetros de los procesos de fusión parcial, cristalización fraccionada y mezcla, con el programa TRAZAS.

José López Ruiz, José-María Cebriá

• The program TRAZAS calculates the compositions of liquids generated by either melting or fractional crystallization, if all the parameters involved in both processes are known. If some of these parameters are unknown, then their value can be estimated using the linear regressions obtained from ad-hoc binary diagrams where different kinds of elements are plotted. Concerning the mixing processes, it is posible to calculate the abundance of trace elements and isotopic ratios in the mixing, if the two component compositions and the other parameters are known. Alternatively, if one component composition and that of the mixing are known, then the other component can be inferred.
