The metallographic and magnetic properties of three iron meteorites from Victoria Land in Antarctica have been studied along with similar analyses of the Russian meteorite Sikhote-Alin. Allan Hills A77255 contains 12.2% Ni, 0.61% Co, and 0.026% P, and consists of a fine intergrowth of kamacite spindles in a microplessitic matrix. Derrick Peak A78003 contains 5.4% Ni, 0.51% Co, and 0.40% P, and was heavily deformed during entry through the earth's atmosphere. Derrick Peak A78007 contains 7.3% Ni, 0.38% Co, and 0.75% P. Extensive shear deformation of schreibersite veins and the occurrence of some comb plessite are evident in the structure. The iron meteorite Sikhote-Alin is a heavily deformed, coarse octahedrite containing 5.94% Ni, 0.38% Co, and 0.46% P.
