Hello Jay and List,

This description still leaves me a little puzzled as there should
not be anything like metal flakes and mm-sized brassy inclusions.
I've been looking at my six Allende slices (the largest having a
diameter of more than 2 inches) but the only features I could detect
that somewhat resemble your description are orange-colored "specks"
and a look at figure 6.6 (an Axtell specimen in full color!) in O.R.
Norton's CEM (p. 107) says: "Weathering of the meteorite has altered
some of the chondrules turning them an o r a n g e color". There
should be so many Allende slices in our collections that it would be
interesting to hear more about what Jay observed from other list
members!

Best regs,

Bernd
