Hiho, I'm thrilled, maybe now many readers of the list rush to their drawers and showcases, to look for more examples of other falls, where they thought before, that the lighter colour was due terrestrial oxidation and the individuals not that fresh.
Let's wait, what they'll find! Martin -----Ursprüngliche Nachricht----- Von: Jason Utas [mailto:meteorite...@gmail.com] Gesendet: Mittwoch, 29.

Good observation, though -- it makes sense that H's would still show at least some hematite presence, if that is was causes the red coloration. The first link in my last email goes against what you say above. Note that the pictured stone has a black, frothy rear and a reddish shield-shaped front.
