We have analyzed metallic and silicate phases in the IVA iron meteorites and two related stony irons, Steinbach and Sao Joao Nepomuceno. Analyses of bulk metal phases in the two stony irons using INAA show that they plot ...
Metallographic cooling rates of group IVA iron meteorites have been recalculated based on the most recent Ni diffusion coefficients and phase diagram. The cooling rates are revised upwards by a factor of ca. 15 relative ...

We have investigated the thermal history of the IVA iron and stony-iron meteorites to help resolve the apparent conflict between their metallographic cooling rates, which are highly diverse, and their chemical trends, which ...
