Scientific paper
This paper presents: (1) a simple analytical relation among closure temperature (T(C)) of cation ordering, cooling rate at T(C), and bulk composition (X(Fe)) of orthopyroxene, (2) results of very precise site occupancy determination of three orthopyroxene crystals from the Steinbach stony-iron meteorite, and (3) the thermal history of this meteorite as reflected by cation ordering in the OPx crystals, silicate mineralogy, and metal compositions. T(C) is defined to be the temperature at which the observed or quenched site partitioning of Fe and Mg is in equilibrium (Ganguly, 1982).
