February 3, 2002 Greetings Mr. Steve Schoner, and Fellow Meteorite Enthusiasts!
A thought occurred to me about your interesting post regarding the octahedritic impactor that formed Meteor Crater and its ties to being a possible iron breccia of some sorts. >From your intriguing research, you also stated in the post that the famous Winona meteorites may be directly linked to the space rock that created Meteor Crater in the form of stony inclusions. With this possibility, I think it is wise for a closer examination of the outer surface on Winona fragments. Despite my unfamiliarity with this type of meteorite (including weathering grade), was there or are there any signs of fusion crust present? If there is, appearing like the crusts on so many studied meteorite falls, (including any possible traces of flow lines and orientation), then I would think chances are that it may have broken off the iron mass while still plummeting. On the other hand, if a crust is present, but somehow different in origin as through the heat generated by a major shock related event, then suspicions point to the possibility that it was thrown out of the crater like many of the iron fragments were upon impact. But this brings up an additional question, of which I have wondered about. Is it known whether or not meteorite fragments that survived a large impact event with earth, would still possess fusion crusts of some sort and be different in any way compared to common forms produced by luminous flight? Lastly, is it known if the Winona meteorites are highly shocked? In any event, I hope you will get permission to investigate that possible fragment of another Winona meteorite, to better prove your own suspicions. Please keep in mind, however, that most of this e-mail is just quick speculation. Long strewn fields! Mark Fox Newaygo, MI USA __________________________________________________ Do You Yahoo!?
