Buchwald's (1975) theory of thermally induced cracking in Serrania de Varas is critically examined from the standpoint of elementary stress analysis. New metallographic observations are presented. It is suggested that thermal cracking is unlikely to

Measurements on the metal of the LL chondrites Appley Bridge, Jelica, Olivenza, and Khanpur have shown that the Co: Ni ratio of the metal is near 1.24 and that Prior's law appears to be followed to some extent within the LL group.

In terrestrial metallography “hot-working” is plasticdeformation above the recrystallisation temperature, and attention is drawn to possible hot working effects in the parent γ-phase of octahedrites. Spinel twinning of the γ-phase and polycryst

Experiments are reported on the chemical diffusion coefficients in the copper-nickel system for the two pure metals and also with the presence of thin (0.00002 in.) intermediate layers of Au, Sn, Zn or Cd. Au or Zn has small effect whilst Sn or Cd ac

Bevan and Axon (1980) proposed that polycrystalline γ (taenite) in the unequilibrated (H3) chondrite Tieschitz is a relic of rapid, non-equilibrium solidification of Fe-Ni-S melts during chondrule formation. Scott and Rajan (1980) dismissed our obse

It is now generally accepted that meteorites are fragments produced by the collision of parent bodies of asteroidal dimensions. Optical metallographic evidence suggests that there exists a group of iron meteorites which exhibit structures similar to
