[meteorite-list] New or maybe old QUESTION??????

[Göran Axelsson]

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.
