Pekka & The List,
I think we must use Monica Grady et. al. and the
recent 'Catalogue of Meteorites' as the definite authority
of what constitute a meteorite fall/find or not.
Brunflo and Osterplana is included in the Catalogue.
As seems to be indicated by other postings here, there are other
quarries where there are fossile meteorites in Sweden. They should
be included as seperate entities if it is possible to indetify their
mineralogy as separate falls.
In an international discussion of meteorites, no country can choose
their own individual criteria for what is a meteorite or not.
I don't see a clear sign that Sweden has done that either...

Another thing that puzzles me is why on the page on the link to swedish
meteorites you have supplied (which I have known for some time),
http://www.nrm.se/mi/swemet.html.en
Muonionalusta is numbered I-IV...!

Why, does this mean 'Muonionalusta' is four (or now five and even more)
(totally) different iron meteorites??
The entry in the 'Catalogue of Meteorites' does in no way
indicate this:

'A mass of 7.5kg was found 2.5 miles WSW of Kitkiojärvi in Muonionalusta.
Description, with an analysis, 8.02 %Ni, A.G. Högbom (1908).
Measurements of the Widmanstätten figures on two pieces suggest tetragonal
rather than cubic symmetry, D. Malmqvist (1948).
A second mass of 15kg was found in 1946, and a third of 6.2kg in 1963,
F.E. Wickman (1964).
A fourth piece was recovered in 1988 (approx 6 kg), Lagerbäck and Wickman
(1997).
Analysis, 8.42 %Ni, 2.24 ppm.Ga, 0.133 ppm.Ge, 1.6 ppm.Ir, R. Schaudy et al.
(1972).
Description; weathered, V.F. Buchwald (1975).
Cooling rate, K.L. Rasmussen et al. (1995).'
