[meteorite-list] Samples

[Peter A Shugar]

Hello Listies,
Maybe someone can answer this for me.
Where did the 20% value come from to classify a meteorite? If a meteorite were found
that, say , was 1.2 grams, unpaired with anything else, then the sample must needs be
.24 grams, if I've figured right. This is a very significant portion of the meteorite.
Then on the other hand should one be found that was 1 ton, the sample would be 400
pounds. If a classification can be done with .24 gram, why can't it be done with a much
smaller piece of the 1 ton meteorite?
Just learning here, please bear with me.
Thanks,
Pete
