Hey!
I never thought that I had to correct you in the field of meteoritics.
:-)
Sweden does have a couple of old coal mines but the fossile meteorites
is found in lime stone quarries.
I have also been shown in the roof of a mine (south of Kumla) of a
structure that was claimed to be an impact crater (or impact pit) but I
haven't been able to find anything published about it.
That was before I got hooked on meteorites so I didn't know what to look
for or ask. The age of that quartzite strata should have been in the
range of 400-600 million years.

You can google them but they are clearly hundreds of
millions of years old, and you can still see clear
chondules in pieces.

List,
Maybe this has been asked and answered (sounds like
a lawer thing) and maybe
not.
Since I am relatively new to collecting and
certainly not an Expert in any
area of meteorite study (with the exception of
magnetisum (from the sky
magnetic VS made a magnet by processes here on
earth).
Here's my question:
A geologist digs in an area that he thinks there
will be the likelyhood of
finding a fossil. Maybe he gets lucky and maybe
finds bunches of them.
Has anyone ever found a meteorite buried deep in a
layer that is thousands
or even millions of years old?
Years ago--long before I became an obsessed, crazed,
meteorite addict,
while teaching a series on earthquakes, I had found
a video of a scientist
standing with one foot on the Pacific plate and the
other foot on the North
Americian plate, ie astraddle of the San Andreas
fault line. In back of him
was a small vertical clift of maybe 10 feet and you
could plainly see the
shift (approx 15 inches) in the layers of sediment.
Now I've got to thinking (some say this is my
problem--Thinking) that these
meteorites have a tremendous terestial age. If the
earth is bombarded by
these meteorites throughout the aeons, then there
should be a record, ie
evidence in the form of buried craters (see the
Odessa,Tx crater) -- Approx
100 to 110 feet deep that has been filled in till
it is only 25 to 30 feet
deep now due to wind blown sand (mostly). I've got a
pamplet of "Occasional
Papers of the Strecker Museum" from Baylor
University showing a neat cross
section of the Odessa Crater.
How much investigation into the cross section
structure of the sediment
layers, looking for evidence of craters has been
done? Has there ever been
an accidential discovery of a buried crater in a
clift side. Lots of these
erroded mesa exist out west. Maybe evidence is
visable there.
Surely Valeria is not the only animal killer out
there.
Maybe another animal drilled by a passing meteorite
with the coresponding
meteorite near the body. Maybe there's no body but
the meteorite is still
there buried in the deeper layers of sediment. Maybe
tektites are the only
surviving evidence.
In a nutshell, has there ever been a meteorite found
at a depth of sediment
that is plainly very old?
