Dear All,
So what will be the opinion when an iron or pallesite comes out of there?
Two or three different chondrites you say and we will call them all H5
regardless of the LL5 to H5...mmm....seems like there needs to be a
bunch more classification to do to me. With out classification, maybe
they are not unlike some NWA's...orphans from a known location?
Not to feed the ducks,
Dave Freeman
