Description
AFC3D is an original graphical free software developed in the framework of the R scientific environment and dedicated to the modeling of Assimilation and Fractional Crystallization without (AFC) and with (AFC-r) recharge, facilitating the search for the solutions of the equations originally proposed by DePaolo (1981; 1985) and first solved in a graphical way by Aitcheson and Forrest (1994). The software presented here allows a graphical 3D representation of rho (mass of assimilated crust / mass of original magma) as a function of r (rate of crustal assimilation / rate of fractional crystallization) and beta (recharge rate of magma replenishment / rate of assimilation) for each element/isotope, finding a coherent set of (rho, beta, r) parameter triples in a mostly automated way. Mathematically optimized solutions are derived, which can and should then be discussed and evaluated from a geological and petrological point of view by the end user. The presented contribution presents the software and a series of models published in the literature, which are discussed as case studies of application and whose solutions are sometimes enhanced based on the results provided by the software.
