The "shatter-cones" appear to be aragonite crystals.
The samples are all m-wrongs.
This paper would never pass the peer-review of Club-Space-Rock,
how did it get past the Cornell University Library?
http://arxiv.org/help/endorsement
How did this ever get published?"
If a person looks at the endorsemen web page at
http://arxiv.org/help/endorsement , it specifically
states:
"The endorsement process is not peer review."
Thus, the articles posted to arXiv are not peer-reviewed.
Over the years, I have noticed that the arXiv endorsement
system, although it allows "publication" of articles at a much
lower cost than conventional peer-reviewed journals, also
allows some rather questionable material to at times to be
"published" on arXiv. This material includes catastrophist
pseudoscience such as "Tails of a Recent Comet" by Milton
Zysman and Frank Wallace at http://arxiv.org/abs/1004.0416
and long discredited and scientifically illiterate nonsense
about a "pole shift" causing the end of the last glacial as in
"On the change of latitude of Arctic East Siberia at the end
of the Pleistocene" by W. Woelfli and W. Baltensperger at
http://arxiv.org/abs/0704.2489?context=physics.geo-ph
A person has to take a critical look at what appears on
arxiv.org and not accept it at face value. It appears the
arXiv Blog simply repeats what the article is about
without making a critical examination of the article's
content. It is largely an Internet version of a press
release and should be viewed with the same skepticism
and critical eye as any press release.

Geological Survey of Canada fails to return piece of meteorite he discovered
In “Geological Survey of Canada fails to return piece of meteorite he discovered” at
http://www.mail-archive.com/meteorite-list@meteoritecentral.com/msg110706.html
MikeG wrote:
“I am a bit confused here. I didn't see the name of the meteorite
mentioned in the article, only that it was found in the Yukon in
1986. Is this an unclassified fall or find?”
It is an unclassified find. According to the news articles, the
Canadian Geological Survey geologists have determined that
it is a meteorite.
MikeG stated.
“Also, a $1000 payout for a 243g meteorite works out to a mere
$4/g - which is pretty good for a highly-weathered ordinary
chondrite find. But a fresher, recent fall should fetch more than that.”
According to the below article, that was the lower end of price
range that Attorney General of Canada Office appraised it as
noted in:
Decade-long disagreement over meteorite back in court
(A more than 10-year battle Daniel Sabo has had with the
Geological Survey of Canada (GSC) continued Monday in
the Yukon Court of Appeal.) by Stephanie Waddell, Whitehorse
Daily Star, November 6, 2012
http://www.whitehorsestar.com/archive/story/decade-long-disagreement-over-meteorite-back-in-court/
In this article, Mrs. Waddell wrote,
“While Sabo has estimated the rock’s value at $12.1 million,
Alexander Benitah, who’s representing the Attorney General
of Canada in the case, pointed to estimates that had it come
in between $1,000 and $2,500 based on the evidence of the
GSC.
He argued Sabo’s valuation is based solely on the highest-priced
meteorite Sabo found on the Internet, while the $1,000 to $2,500
is based on the evidence of the GSC.”
Finally, MikeG stated.
“Lastly, the guy sounds like some sort of conspiracy nut who
claimed GSC switched out his meteorite and gave him an
imposter in return. Then he demanded $12 million in damages,
which was denied.”
The below articles are rather revealing of the entire controversy
and Daniel Sabo’s state of mind.
1. Meteorite conspiracy could be on the rocks by Tristin Hopper,
Yukon news, September 12, 2008 http://yukon-news.com/news/9865/
2. A tale of two meteorites by Tristin Hopper Yukon News,
July 18, 2008, http://www.yukon-news.com/sports/9552/
For example, Mr. Sabo believes not only did the Canadian
Geological Survey replaced his meteorite with a carefully sculpted
replica made from another meteorite, but they also gave his
original meteorite to NASA’s Johnson Space Laboratory. He
also claims that the “fusion crust” on the specimen was faked
using “aluminum — embedded with iron particles to simulate
the magnetic properties of magnetite.”
