[OT] South African Rock and Mineral Dealer Needed

[OT] South African Rock and Mineral Dealer Needed

Dear Friends,

Is anyone on this list either a dealer in South
African rocks
and minerals; know of a South African dealer in rocks
and
minerals, whom I can contact; or have contacts with
South
African collectors. If so, could you contact me off
list.

I looking for specific rock type from South Africa for
research
purposes.

Direct or indirect participation in the successful
acquistion
of this material will be rewarded, in addition, to the

purchase of rock samples with unique trade material of

interest to list members. For more details, contact me
off
list.

Best Regards,

Paul

Mining Manicouagan impact crater

Mining Maricouagan

I found the below note in the otherwise dry
world of financial announcements.

Manicouagan Minerals Inc. announces closing of
its public offering and listing on the TSX
Venture Exchange
http://www.newswire.ca/en/releases/archive/December2004/23/c8616.html

"The Corporation is engaged in the exploration of the
Manicouagan meteorite impact crater in central Quebec.

These efforts have been concentrated on seeking
prospective areas of nickel-copper-platinum group
mineralization. The Corporation believes that the
similarities between the Manicouagan crater and the
Sudbury mining district are of a significant enough
technical merit to warrant an extensive exploration
program. Less than 5% of the crater has been explored
to date and geophysical surveys have identified four
deep magnetotelluric anomalies, which are located
toward the center of the Manicouagan crater. The
Corporation has accumulated rights to claims
totalling in excess of 1,300 square kilometres in
the crater area."

Another news release, of November 2004, which I found
was:

"News release via Canada NewsWire, Toronto
416-863-9350
Attention Business Editors:
Manicouagan Minerals Inc. - Drill Results Provide
First Evidence of Nickel and Copper at Depth at the
Baie du Nord Project in the Manicouagan Crater"

This press release stated that in drill holes they
found nickel
and copper at depth consistent with base-metal rich
sulphide
mineralization, which occurs in surface outcrops
within the
Manicouagan impact crater. According to the press
release,
drilling found "significant" "base-metal values"
within
metagabbro sills intruded into foliated feldspar
hornblende
gneiss country rock.

It sounds someone has taken the idea of exploring for
impact
associated mineral deposits in "virgin" impact craters
quite
seriously. I guess only time will tell whether the
shares in
this company will become collectibles or prove to be
visionary
application of the study impact processes.

It seems like that known commercial base-metal
deposits
associated with impact craters were only determined to

be associated with an impact crater after the mineral
deposits
were found. Is this the first time that someone has
gone to
an impact crater with no known ore deposits and gone
prospecting for them since Barringer’s ill-fated
attempts
at Barringer Crater?

The official paperwork on it can be found at:

Fri Dec 24 23:5Ron Baalke quoted:

Asteroid gets initial elevated risk
rating, but impact unlikely
By JOHN ANTCZAK, Associated Press
December 23, 2004

...text deleted...

Asteroid 2004 MN4, believed to be about 1,300 feet
long, potentially could impact Earth in 2029, based
on a limited number of initial sightings, said
Donald Yeomans, manager of the Near Earth Object
Program at NASA's Jet Propulsion Laboratory in
Pasadena."

I went to http://www.lpl.arizona.edu/impacteffects/ ,
and did some calculations.

Assuming an average projectile velocity of 17 km/s,
and 45 degree entry angle, the result for the impact
of a dense rock object of this size in sedimentary
rock is:

"Transient Crater Diameter: 4.95 km = 3.07 miles
Transient Crater Depth: 1.75 km = 1.09 miles

Final Crater Diameter: 6.13 km = 3.8 miles
Final Crater Depth: 0.511 km = 0.317 miles"

In case of an iron projectile, in sedimentary rock,
the result is:

"Transient Crater Diameter: 7.08 km = 4.4 miles
Transient Crater Depth: 2.5 km = 1.56 miles

Final Crater Diameter: 9.19 km = 5.71 miles
Final Crater Depth: 0.577 km = 0.358 miles"

If this hits land, someone will definitely have a bad
day and one hell of tourist attraction afterward.

Given its small "footprint", if the rock could be
directed to a specific piece of property, I image,
a lot of states could find a 80 square area they
would sacrifice as ground zero for its landing given
the unlimited tourist potential such a crater would
have.

Is there any way to figure out what sort of tsunami
a rock this size would cause?

I found a listing of the area of each state in
"Land and Water Area of States, 2000 (in square
miles)" at:

http://www.infoplease.com/ipa/A0108355.html
http://www.factmonster.com/ipka/A0108355.html

Using the figures from XXX's post and the "total
land area present within each state, I get the
below number of meteorites per square mile for
each state. The order in which data is listed
is State; number of meteorites; (rank in total
area of state); land area in square miles;
(area in square miles per meteorite found).

In 1990, there were three states with less
than 1,000 square miles per found meteorite.
They are New Mexico, Kansas, and Texas.

The states with less than 2,000 square miles
per found meteorite in 1990 were Connecticut,
Colorado, Kentucky, Tennessee, Nebraska, North
Carolina, and Oklahoma.

This is true. Two have been found in
Louisiana, which now makes Louisiana entry
to be:

Louisiana 2 (31) 43,562 (21,781)

If there are now 13 known meteorites from
Wyoming then, it is now:

Wyoming 13 (10) 97,100 (7,469)
