Distribution of Meteorites Around Small-Size Craters?

Paul H bristolia at yahoo.com
Sat Apr 16 17:25:15 EDT 2005

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.

"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."

"Did the dinosaurs really go abruptly extinct 65
million
years ago at the Cretaceous-Tertiary ("K-T") time
boundary, or was their K-T extinction the end result
of a gradual decline over millions of years? The
imperfect record available from scarce dinosaur
remains has made this question a true enigma
and the source of a long-standing and contentious
debate. David E. Fastovsky and Peter M. Sheehan
conclude, after a careful review of the fossil record
from the best-documented dinosaur sites (in
North America), that the extinction was indeed
geologically instantaneous. The authors argue
that the sudden die-off was different in scope
from previous fluctuations in dinosaur diversity
through the dinosaurs' 160 million years on Earth.
The authors consider the dinosaurs to have been
direct casualties of the K-T impact of an asteroid
with Earth and review several potential explanations
for the mechanism of the extinction. All of these are
concordant with the asteroid impact as the ultimate
cause."

Discovery of distal ejecta from Sudbury impact event

Discovery of distal ejecta from the 1850 Ma Sudbury
impact event
from "March Geology and GSA TODAY" media highlights
at:

http://www.eurekalert.org/pub_releases/2005-02/gsoa-mga022805.php
http://www.gsajournals.org/gsaonline/?request=get-current-toc&issn=0091-7613

Addison, W. D., and others, 2005, Discovery of
distal ejecta from the 1850 Ma Sudbury impact
event. Geology: Vol. 33, No. 3, pp. 193–196.

Addison et al. announce the discovery of impact
ejecta from the Sudbury, Ontario, Canada,
structure, the second largest and third or fourth
oldest extraterrestrial Earth impact site. At 1.85
billion years old, these Paleoproterozoic ejecta
are three times older than the previous oldest
dated ejecta linked to a specific impact (Acraman,
Australia, 0.59 billion years old). It is also larger
than the well-known Chicxulub, Mexico (0.065
billion years old) impact linked to the extinction
of the dinosaurs and many other species. The
young Chicxulub impact, particularly its well-
preserved worldwide ejecta debris layers, have
produced criteria to judge other large ejecta
deposits. Foremost is the occurrence of sets of
microscopic parallel lamellae in quartz and
feldspar grains produced by the intense shock
generated at the point of impact. Secondarily,
the impact generated a megaplume of vaporized,
melted, and crushed crustal rocks, creating molten
droplets containing bubbles of gas, and larger
accreted balls of dust and rock shards called
impact accretionary lapilli. These features, and
more, are seen in the Sudbury debris. The debris
(ejecta) studied here, landed 650 km west northwest
of Sudbury near Thunder Bay, Ontario, Canada, and
875 km west of Sudbury near Hibbing, Minnesota,
United States. This huge impact likely deposited
debris all around Earth, but it is very difficult to
find because so much of the evidence has been
destroyed in the recycling of Earth's crust by plate
tectonics. Life at the time of the Sudbury impact
was confined to the oceans and consisted of
unicellular and colonial unicellular organisms. So
far, Addison et al. have found no evidence of
extinction of this life. However, future studies may
link this impact and its ejecta with changes in the c
lassic Gunflint Iron Formation unicellular organisms
and their photosynthetic microbial mats, which
helped produce Earth's atmospheric oxygen.

Mining Manicouagan impact crater

Mining Maricouagan

Paul H

Sat Dec 25 11:25:32 EST 2004

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?

Asteroid gets initial elevated risk

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?
