摘要:

AbstractExamination of an iron meteorite found in South Africa discloses it to be a coarse octahedrite containing 6.90 weight‐percent nickel. The meteorite body contains several inclusions of troilite, or troilite plus graphite, and at least one of pure graphite veined with kamacite. Kamacite, cohenite, and phosphides are the other major constituents of the structur

摘要:

AbstractThe principal data about the fall and the distribution of the fragments of the Bur‐Gheluai, Bur Acaba, Somalia (CN = EO436,024) meteorite are collected. A complete individual, weighing 744.2 g, preserved in the Geological Institute, Agricultural Dept., University of Perugia, Italy, is described in some detail. Crust morphology, mineralogical composition and structure are studied. Optical data are established by microscopical analysis of eight thin sections and two polished surfaces. Compared with electron‐probe analysis, they are found in good agreement. Bur‐Gheluai is an holocrystalline, olivine‐bronzite chondrite, with evident features of recrystal‐lization and met

摘要:

AbstractA survey by air and on the ground revealed no depression at the place supposedly called Ka‐imu‐hoku, Hawaiian for “The Star Oven”, on the island of Lanai. It had been reported as a “pit in the sand” or “the place where a meteor fell”. Reasons are given for believing the name was based on native observation of a nineteenth c
