Beda, I have seen a meteorite with a crust of sand from NWA that was some
years ago, so I dont know which one it was. It was being sold in the USA.
Of course, some Oman meteorites exhibit the same thing.

Subject: [meteorite-list] Sand-crusted, polished OC slice
Hello listmembers
From a donated collection I unpacked an unlabelled slice of an ordinary
chondrite, with a very high quality polish. The meteorite is crusted with
an up to 5 mm thick rind of sand grains, well rounded quartz mostly,
cemented by oxides released from the meteorite. I assume that the slice
was acquired more than 15 years ago, material looks as H4-5, W3. Does this
sound familiar to anyone?
Thanky for any hints
Beda Hofmann
