Fig. 3: Evolution of condensates in the Urey–Craig diagram.
From: Non-equilibrium condensation of the first Solar System solids
This diagram shows the iron redox state of condensates along the condensation path calculated with KineCond, compared with chondrite compositions (coloured shapes). The x-axis shows molar fraction of oxidized iron, whereas the y-axis shows iron in metal and sulfide, normalized to silicon and to the solar Fe/Si ratio. Coloured solid lines trace the redox evolution during condensation process of types A, B and C for various (P, Tc) cooling conditions. a, Condensation paths of a solar-composition gas with FNRs. b, Same as a, but for SNRs. All trajectories end on the solar iron–silicon line. c, Condensation paths for non-solar gas compositions, using moderately fast reactions. Colours correspond to different gas compositions and marker shapes denote different cooling rates (X = −6, −5, −2).
