Some meteorites are very "friable" meaning you can crumble them with little to moderate hand pressure. Friable meteorites are well know but not necessarily common.
The rust marks are likely just that-- rusting iron flakes and can come from handling and storage conditions. As I recall this arrived during a monsoon. You might be able to arrest the rusting/lawencite disease using the procedures for stabelizing irons but perhaps another list member can elaborate on treating a friable stone such as Burbojle(sp) which fell through sea ice and deeply into the underlying mud.

I have noticed brown specks on my Orissa chondrite ....are these rust marks? Is there anyway to
prevent this from happening or at least control this. Another silly doubt I have is that this meteroite is very brittle...just breaks apart when pressed
hard...is this common for chondrites?
