Henbury Craters, Australia
Iron. Octahedrite, medium. (IIA) “CM” REF: P. 165, “HBIM” REF: P. 638, and “ARN’S” REF: P. 130. Also see “Meteorite Craters and Impact Structures of the Earth”, P. Hodge, P. 67-70 for additional information on the Henbury Craters. O. Richard Norton has provided a condensed description of the theory on the formation of the craters, with descriptions of the meteorites found there, in “Rocks From Space”, P. 138-142, with several black and white photos of specimens, as well as an aerial view showing three of the craters.
The Henbury Crater Field, includes approximately 13 craters, and was first identified about 1931. The Aborigines, however, were aware of the Henbury Craters at a much earlier date and, based upon their legends, it is speculated by researchers that when the Henbury event occurred, it may have been witnessed by the Aborigines living in the area at that time. The largest crater is elliptical, measuring approximately 720 X 360 feet (another report gives the size as 180 X 140 meters), and the smallest crater measures only about 6 meters in diameter.
The distribution and appearance of Henbury irons suggests that the Henbury Craters were formed by a small swarm of many individual meteorites. Many the meteorites fell intact and buried themselves, and recovered examples of this type sometimes show the typical regmaglypts and flight orientation seen on iron meteorites from other worldwide localities. Most of the larger members of the fall, however, are presumed to have exploded before, and/or upon impact, producing quantities of bent and/or twisted masses with shrapnel-like form. Many specimens have sharp, ragged edges, attesting to the great forces and heat to which they were subjected. Polished and etched specimens from Henbury will show different characteristics, depending upon their method of formation, i.e.: 1. original, unshocked specimens which fell and were not effected by the explosions, or 2. shocked specimens which were subjected to stress by high heat, or mechanical deformation caused by the above-ground, as well as inter-crater explosions. Some polished/etched specimens will exhibit stressed areas, as well as areas where the Widmanstatten pattern is pronounced, and sharply defined.
END CUTS: Items D) and E) are larger, individual end cuts with the cut surface
polished, etched, and coated with Krylon for preservation, same as the smaller exhibit
pairs above. The outside surfaces are in natural condition with the typical very thin,
red-brown oxidized surface. Item A) is priced at $1.50 / gram. Item D) is priced at
+/- $1.00 / gram, and item E) is priced at +/- $1.20 / gram.
A) 86.15 grams 1 3/8" X 1" X
7/8" $ 129.25 SOLD
D) 565.60 grams 4 ” X 1 1/2” X 1 1/2” $
565.00 SOLD
E) 812.00 grams 3 3/8” X 2 1/2” X 1 5/8” $ 974.00
COMPLETE SLICE: This one of a kind, complete slice has been polished and etched on
BOTH sides, to reveal the extra sharp Widmanstatten pattern of this unshocked specimen.
Both cut/etched surfaces have been coated with Krylon for preservation and the thin,
natural red-brown edges (natural outside surface of the meteorite) are in perfect
condition around the entire perimeter of the slice. A very small Troilite nodule can be
seen in the lower right corner of the slice, in the accompanying photo, and another small
Troilite nodule is present on the back of the slice. This one of a kind specimen is
excellent for exhibit, and is priced at +/- $2.65 / gram.
F) 224.70 grams 3 1/2” X 3 3/8” X 1/4” $ 595.00 SOLD
