BOXHOLE, PLENTY RIVER, NORTHERN TERRITORY, AUSTRALIA
Iron. Octahedrite, medium (IIIA) “CM” REF: P. 79, “HBIM” REF: P. 338, and “ARN’S” REF: P. 40. The Boxhole Crater is a 170 meter diameter, circular depression, discovered during a geological surveying of the area in June, 1937 near Dneiper (Boxhole) Station. Several large masses of the Boxhole meteorite have been located, including one weighing 82 kg. It has been concluded, from scientific studies of the meteorites found, as well as from investigations of the crater site, that about 5,000 years ago a large iron body apparently penetrated the atmosphere with no appreciable loss of speed. At a high altitude, small parts of the surface of the meteorite, probably protuberances and other irregularities, were torn off and proceeded as independently falling bodies. The main mass exploded upon impact, created the crater, and hurtled numerous fragments up to a distance of a few kilometers away. A study of etched slices of specimens from Boxhole shows that the Widmanstatten lamellae are usually bent and torn out in long stringers, similar to some of the specimens from Henbury. Slicing would probably reveal the distorted structure in all of the uncut examples below. Each is a complete individual, as field collected, with a very thin, reddish-brown, natural oxidized surface. If desired, a minimal amount of cleaning (i.e., with a wire brush) would expose the bright, silvery-metallic color and luster of the unweathered meteoritic material. Pricing is @ +/- $3.00 / gram.
