Consolmagno, G. J. Io: Thermal models and chemical evolution. Icarus 47: 36-45, 1981.

principal objective: "which starting conditions can evolve into Io as it is observed now?"

starting conditions - T, P, mode of energy transfer during condensation, relative positions of Galilean satellites

thermal history- "what range of T and P have been reached inside Io?"

chemical history - chondrite compositions, evolution
