An additionally interesting characteristic of this meteorite in the broken- off fusion crust on the edges of typical specimens.

Henbury craters are a result of one of the few impact events, that have occurred in a populated area (few other examples are Kaali crater in Estonia and 2007 Carancas impact event in Peru).

The reserve is located 145 km (90 mi) south west of Alice Springs and contains over a dozen craters, which were formed when a fragmented meteorite hit the Earth’s surface.

Recent years have produced almost exclusively broken, field weathered and/or dirt stained stones, and, on at least one occasion, a prospective buyer was beaten by banditos. So, while most collectors cannot afford an SNC ("Mars rock") and few in the world have a piece of the earth's moon, you can easily afford an excellent specimen of likely Mars' lunar material!

(research since the Phobos report indicates several OTHER possible sources in the asteroid belt also give off identical surface reflection spectrogram readings - in fact, some now feel that Phobos, itself, may be one of these asteroids, having been "captured" by Mars) One of the most spectacular falls of the 20th century.

Henbury is one of five meteorite impact sites in Australia with remaining meteorite fragments and one of the world's best preserved examples of a small crater field.

At Henbury there are 13 to 14 craters ranging from 7 to 180 m (23 to 591 ft) in diameter and up to 15 m (49 ft) in depth that were formed when the meteor broke up before impact.

magazine, Nov., 1996 - cover story) Scientists believe the E chondrites come from within the orbit of Mercury (as certain constituents could only have formed in heat that close to the sun) Many feel Mercury, itself is the actual body of origin for the Es. "Rubin and Scott argue effectively for two distinct impact events with an intervening period of brecciation through meteoroid bombardment to explain the diamonds and partially melted clasts...." (Kempton, 1996) Besides for all that, it is a VERY zappy meteorite visually. That is what I will offer it for here 700- .695g(EUC unbr) Found Morocco, 2000 30° 33' N., 4° 54' W. Later, a second, 400g stone was recovered which was originally thought to be a new Chassignite. Still, for the first ten years after the fall, material was readily available to the private collector.

$100/g : Acapulcoites are named after this unique meteorite - and there are precious few of them - and they are ALL small. However, Rubin of UCLA identified it as a second stone of Agoult. Ongoing research on this unique, unbreciated eucrite will undoubtedly yield interesting information. Since that time, however, whole specimens have become increasingly difficult to obtain.

This material was selling at the Denver show this year (2001) at $600/g dispite the deflated market and dramatically reduced attendence. This is a SPECTACULAR piece at an increadably low price of $125/g! This meteorite is almost undoubtedly the most researched meteorite to date.

Thick pieces of it can be found elsewhere in the US for $250/g - here it can be had in THIN partslices at the same price, yielding vastly greater surface area to weight ratio. : 64.4 gram endcut, showing orientation and LOTS of fusion crust. It contains extremely large chondrules, various organic compounds and inclusions of an aluminum-calcium-titanium mineral that may be the first silicate minerals to have condensed within the solar nebula while our sun was only a proto-star in the process of being born.

As reported by the BBC: " On Christmas Eve 1965, a very strange event occurred in the Leicestershire village of Barwell...
