Hi Bernd and List,

I agree with Kilabo, Saratov and Sulagiri. I've also found the
majority of LL6 meteorites to be friable or "sugary" in some
instances. Some are more cohesive than others, but most will "erode"
grains readily. Bjurbole crumbles easily and sheds chondrules when
handled roughly. Bensour is crumbly as well. NWA 4734 lunar can be
friable and tends to crackle apart. Many carbonaceous chondrites tend
to be crumbly - Murchison, Tagish Lake, Orgueil, Karoonda, etc, while
CV and CR types tend to be sturdier and take a hard polish.

Best regards,

MikeG
