Subject: [meteorite-list] "Fossil" as a 17th century term for excavated
meteorite?
Message: 1
Hi list,
Can anyone tell me when the word "fossil" was first used to describe
meteorites of this kind?
The use of the term to refer to obtaining anything by digging comes
from the early 17th century, its use with chiefly organic remains a
century later (1736). I was wondering whether the word, in the field
of meteorites, had come to us from before 1736.
Fossil: 1619, "obtained by digging" (adj.), from Fr. fossile, from L.
fossilis "dug up," from fossus, pp. of fodere "to dig," from PIE base
*bhedh- "to dig, pierce."

Message: 2
I can't answer when, but I do think that using
"fossil" as an adjective applied to ancient
meteorites is perfectly acceptable. In geology
(and other sciences) it usually means anything
preserved from an earlier geologic age, not
necessarily something living. "Fossil meteorite"
is as valid as "fossil water". It is when using
"fossil" as a noun that you would be on thinner
ice, since that seems reserved for a remnant of an organism.

Meteorites & What They Mean To Us. (MW)
Message: 4
Ok, it's been a while since I posted anything on
the MW site, so I figured I'd put something up
that I think everyone might have an appreciation
for. Something fun, light and educational. Some
of you who are familiar with the Earth Impact
Database already know about the craters listed
but I found this neat little link on Answers.com
that has a plethora of information on impact
craters that's not in the database. And it's not
just craters on earth either. There's links to
info about craters on just about every other
planet in our solar system and what impact list
would be complete without photos of our nearest celestial body the moon.
I've also written a short article on impact
craters, meteorites and what I think they mean
to most of the people who spend almost every
waking hour hunting, researching, studying, and collecting these great rocks.

Hi,
I have found several references from 1871, using Google Book Search.
Viewing is restricted to:
"Fossil Meteorite. A new meteorite has just
been discovered in the miocène ...
This is the first instance on record of a truly fossil meteorite having been"
You can see further examples here:

Blowing that up to Exhibit size, would create

Message: 10
Hi List,
I've read somewhere that it is possible for a meteorite to be
magnetic. Reading that made me believe someone has discovered such a
meteorite(s). Anyone out there on the List want to volunteer
information and/or maybe some pictures (or a link to some pictures)
of such an iron? Let me guess this first, mostly kamacite, right?
If you have pictures, besides wanting to confirm my guess, I am
interested in seeing the exterior, as in flow features and fusion
crust. I would also be interested in knowing just how magnetic it is.

Message: 11
I have 2 lots of freshly cut Seymchan Slices.
My cutting process leave a very smooth surface
and very little sanding and polishing is required to etch these slices.
This is the last of the Seymchan that I have.
If you're interested in either or both lots send
an email off list to bobadebt at ec.rr.com
Thanks
----------------------------------------------------------------------
LOT 1 - 8 Slices / Total Weight 141 Grams / $70
I was testing the limits of my cutting process
by trying to see how thin I could cut a slice so
slice thickness of this lot varies from 1mm to 4mm
They are all about the same size which is approximately 45mm x 35mm
http://i131.photobucket.com/albums/p298/BobaDebt/8Slices.jpg
----------------------------------------------------------------------
LOT 2 - 12 Slices & 1 End Cut / Total Weight 538 Grams / $250
This lot was cut to a consistent thickness of
approximately 4mm, a few slices vary due to
blade changes but overall they are very close.
The last cut is thicker and has a slight taper.

Hello Mike,
~92% of all meteorites are magnetic; all irons, all stony irons, and
nearly all stones are magnetic.
The only meteorites that are not magnetic would be the HED's (some of
these are slightly magentic), as well as Aubrites (though some of
these contain iron as well), planetary meteorites (oftentimes
*slightly* attracted to a neodymium magnet, though one should never
poke such meteorites with a magnet), and Rumuruti chondrites (in this
case, because most of the iron is contained within iron sulfide, and
is thus non-magnetic).
Depending on the stone, a few carbonaceous meteorites are lightly
magnetic, but in general, they tend to be magnetic as well.
Almost all meteorites are magnetic...I don't know where you heard
otherwise, but...yeah.
Regards,
Jason

Hi Michael,
Magnetic can mean more than one thing:
1. of or pertaining to a magnet or magnetism.
2. having the properties of a magnet.
3. capable of being magnetized or attracted by a magnet.
4. pertaining to the magnetic field of the earth: the magnetic equator.
5. exerting a strong attractive power or charm: a magnetic personality.
6. noting or pertaining to various bearings
and measurements as indicated by a magnetic
compass: magnetic amplitude; magnetic course; magnetic meridian.
The definition pertaining to meteorites is #3 not #2.
Best,
ken

seeing the exterior, as in flow features and
fusion crust. I would also be interested in knowing just how magnetic it is.

Hi Jason, List
Perhaps I used the wrong word when I wrote "magnetic". What I was
looking for was info on meteorites that are magnets.
Sorry 'bout that
Mike

It is my understanding that most iron objects
are susceptible to being magnitized, turned into
magnets, if exposed to a strong magnetic field.
So if a meteorite containing iron is exposed to
strong ENOUGH magnets for long ENOUGH [note the
qualifying capitalization], under the RIGHT
circunstances it would not be impossible for SOME to become magnets.
