[meteorite-list] I've found snow in a meteorite

[Göran Axelsson]

Okay, okay, I'm exaggerating  a bit, but it's a really white
inclusion in this meteorite and it's making a nice contrast
to the dark matrix.

I bought a number of both cut and uncut unanalysed NWA:s from
Dean a couple of months ago. When I cut one up to slices I was
greeted by a really nice surprise. In one of the meteorites
there were a white inclusion circa 5 mm across.

Here are some pictures on the inclusion.

The inclusion looks like some medium to fine grained mineral with
grey lines (fractures?) criss crossing it.

Does anyone here have a clue of what this is?

Thanks for looking!
