Guillaume Matton and Michel Jébrak, 2005,
Resolving the Richat enigma: Doming and
hydrothermal karstification above an alkaline
complex. Geology. vol. 33, no. 8, pp. 665–668.

http://www.gsajournals.org/gsaonline/?request=get-abstract&doi=10.1130%2FG21542.1

The abstract concluded:

"The circular Richat structure and its breccia
core thus represent the superficial expression
of a Cretaceous alkaline complex with an
exceptionally well preserved hydrothermal
karst infilling at its summit."

"A model is proposed in which the intrusion
of an underlying magmatic body resulted in
the bulging of the overlying crust and
production of fluids, thus creating a favorable
setting for the dissolution of sedimentary
rocks. Formation of voids has led to the
collapse and brecciation of overlying units.
Thus, Matton et al. suggest that this unique
structure had a terrestrial origin, ultimately
forming from the effects of an intrusion
originating from Earth's mantle."

After I forwarded pictures of non-etched
slices of Shirokovsky and compositional data
concerning the lithic fragments found in its
iron-nickel matrix to a metallurgist friend,
who prefers to remain nameless, I received
this comment:

"Based on the information given I would
concur that this is a man-made material,
probably derived from a furnace and quite
possibly part of a furnace lining, i.e. a
refractory brick that has been strongly
altered by reaction with the molten contents
of the furnace. This is supported by the
very iron-rich composition of the olivine
and the presence of magnesiowustite and
magnesioferrite. This conclusion is also
supported by the reported "eutectic" nature
of the metal-oxide intergrowth."

Having visited either professionally or as a tourist
various countries, collecting and export permits
are not the only matters people need to worry about.
In several countries, specifically ones with internal
security problems, it can also be illegal to possess /
use Global Positioning System units, specific types
of radios, topographic maps of specific types and
scales, and so forth. In planning any sort of
expedition, a person needs to make sure that the
equipment, which they plan to use is not in
violation of a country's law. Although it seems
unfair, it is the responsibility of the person going
to a foreign country to know what is and is not
illegal. Ignorance of the law, as in the United
States and as far as I have found, is universally
never considered an excuse.

On the other hand it can be at times very difficult,
if impossible, for an outsider to completely
ascertain what is and is not illegal in any foreign
country. Foreign countries operate by written and
unwritten rules, customs, and regulations, which
only a native will know. It is quite easy for a
person in planning from afar a visit to visit a
foreign country to overlook some of these laws,
customs, and regulations, which are common
knowledge to the local people. Also, it is difficult
to know from afar the tipping point, at which
authorities will go from ignoring infractions
of the law to enforcing them. It is, unfortunately
very easy for someone to not know what they
should have known when planning a trip from
afar. However, as in the United States, ignorance
is not typically going to be accepted as an excuse
despite such ignorance being unavoidable. This is
unfair, but life is not fair.

(In case of Islamic, Arabic-speaking countries,
geologist friend, who have worked in them, tell
me that the difference in culture and language
increase the potential for mis-communication,
misunderstandings, and very, very unpleasant
experiences by several order of magnitude outside
of the "Cocoon" of guided tours and resorts that
normally surround tourists visiting them.)

About the main solution to this very real problem
is to have someone, who lives in the country, to
which you are going, involved in planning your
trip. Only someone, who lives in the country and
knows the language and customs, will have a
knowledge of the laws governing what you are
doing; what laws are not enforced; what laws are
enforced; the tipping point at which specific laws
will be enforced; and how not to attract unwanted
attention. Finally, I can vouch, from personal
experience, having a citizen of the country, which
are visiting with you and following their advice,
can not only prevent an unpleasant situation, but
also mean the difference between an "adventure",
which you can joke with your friends about over
a beer, and a very, very unpleasant experience.

With 20-20 hindsight. I can see some hint of this
in "Oman Is A Bank Of Meteorites By Hasan
Kamoonpuri, Oman Observer 290801" at:

http://www.newsbriefsoman.info/features/oman_meteorites.htm

In this article, a person can sense the national
pride invested in the meteorites being found in
Oman by the Oman government.

Also, there are these notes:

"According to Dr Hofmann since the year 2000
several precious meteorites have been discovered
in Oman. But many of them are not available for
scientific study because they are in unknown
private hands.'"

and

"One of the biggest concerns bothering the
meteorite experts is that most of the meteorites
are being collected by private collectors for
sale in the open market.""

Unfortunately, likely the main way for anyone to
have known of the type of change in attitude in
a country, of which Robert speculated above about
and would have caused a change from non-
enforcement to enforcement of laws, would have
been by inquiring with someone living in the
country in question. Such changes are not reported
in international news and not considered significant
by the Department of State and, even, the embassy
to be worth reporting given more immediate and
pressing matters of peace, war, and commerce. Most
embassies have far bigger fish to fry and preoccupied
with dodging larger rocks than whether or not laws
about relatively "minor" matter, i.e. collecting
meteorites are being enforced.

Oman’s lunar meteorite sparks exciting cosmic secrets
By Conrad Prabhu, 17th August 2004, Oman Observer
http://www.newsbriefsoman.info/features/lunar_meteorite.htm

In this article, it stated:

"SaU 169 was one of an estimated 3,700 meteorites
discovered during a series of joint field search
campaigns undertaken between January 2001 and
January 2003, says the Omani geologist. "We invested
a total of 339 man-days in the search, which yielded
some 1,334 kg of meteorites, which may have come
from an original 150-200 individual falls. Meteorites
commonly break up in the atmosphere into many
smaller fragments."

According to this article, they collected 1,334 kg
(2935 pounds, 1.46 tons) of meteorites.

Looking for Buried Iron-Shale with a Metal Detector

Dear list members,

If by some chance I had a hunch where I might
find some buried iron-shale, is it possible to find
highly weathered meteorite (iron-shale) with a
metal detector?

If so, what is the approximate relationship between
size of a piece of iron-shale and the maximum depth
at which it can be detected? Also, are there any
special tricks to using a metal detector to look for
buried iron-shale?

Guardian, UK, April 20, 2005
http://www.guardian.co.uk/uk_news/story/0,3604,1464446,00.html

"(Charles) Beichman and his colleagues used an
infrared
spectrograph aboard Nasa's space telescope Spitzer
to look at 85 sun-like stars. Only HD69830 showed
a thick disk of warm dust in the inner section of
the star system. The guess is that every 1,000 years
or so, two asteroids in the belt collide and pulverise

each other."

Distribution of Meteorites Around Small-Size Craters?

Has anyone studied how the meteoritic material found
at impact craters such as Wabar, Boxhole, Henbury,
Odessa, and Morasko was distributed? I am curious if
either the main mass or the major amount of the
meteoritic material was either found inside the main
crater or otherwise directly associated with it in
some
fashion. Or was the meteoritc material simply
scattered
haphazardly about the primary crater in a manner
lacking any discernable association with the largest
crater and pattern?

Any suggestions of published papers relating to this
topic be would be greatly appreciated.

Torino Scale Revised

Torino Scale Revised
Universe Today, April 14, 2005
http://www.universetoday.com/am/publish/torino_scale_revised.html?1342005

"Summary - ( Apr 13, 2005 ) Astronomers searching
for potentially destructive Earth-crossing asteroids
have revised the scale they use to communicate the
risk of impact to the public. The Torino scale, which
still goes from 0 (no chance of impact) to 10
(collision
is certain) has the same classifications, but it's
been
rewritten to give the public a better idea of the
risks
associated with different space rocks. Instead of
"meriting concern", lower risk objects now "merit
attention by astronomers", explaining that
astronomers will be making further observations."
