Scientific paper

The metal phases in a number of chondrites have been studied. Spindle-like exsolutions of the high-Co alpha phases were observed in a matrix of high-Ni-high-Co gamma phase in Olivenza (LL5) and Khanpur (LL5) chondrites. Alpha-gamma interface values were obtained for Jelica (LL6). The bulk Ni-Co contents of the metal phases in these three LL chondrites were consistent with a Prior's Law relationship in which iron partitions between the metal and silicate phases and Ni and Co are concentrated in the metal exclusively. The Ni content of the alpha phase of a selected array of H and L chondrites was about the same as the LL chondrites investigated. There was a distinct Co hiatus of about 1% between the LL alpha and the L alpha phases. Reheating or shock-heating effects were found in Holbrook (L6), Gambat (L6), and Tennasilm (L4) samples.
