Resumen:
The thermal history of mesosiderites is not totally understood yet. Materials with different physical and chemical properties (e.g., silicates, oxides, sulfides and metal)make up the whole rock showing a heterogeneous mineral distribution with variable degrees of recrystallization. Here wereport on new equilibrium temperature calculations made on the silicate pairs high-Ca/low-Ca pyroxene and low-Ca apyroxene/olivine. We took into account only clinopyroxene and orthopyroxene exsolutions present as lamellae and/or blebs.
