The Magma Chamber Simulator is a thermodynamic model for computing the open system evolution of a magma body as it thermally and reactively interacts with Wallrock and possible magma replenishment during cooling and crystallization. The composite system consists of three sub-systems: Magma body, Wallrock, and multiple (up to n=5) Recharge magma reservoirs. The MCS uses one of four MELTS engines coupled to a user-defined brain (IGOR) to track phase equilibria, trace element and isotopic concentrations of all multiphase-multicomponent sub-systems self-consistently.
Tabular and graphical output makes the results of multistep petrological scenarios easy to assimilate and digest. The MCS is able to follow complex scenarios of Fractional Crystallization (FC), Assimilation (A) (of partial melts or stoped blocks) and magma Recharge (R) as defined by the user in a simple input interface (MES_ file). MCS-IGOR supports up to 68 trace elements and all radiogenic isotopes (e.g., Sr, Nd, Pb, Hf etc.). User friendly output makes analysis of results easy to digest and incorporate into third-party graphical and statistical codes or spreadsheets.
