[meteorite-list] Silicated Iron vs. Winonaite

[Jeff Kuyken]

G'day List,

I have a question I'm hoping someone may be able to answer as I don't know 
if I have this right. My (basic) understanding is that the silicate parts of 
a silicated iron are actually Winonaite material. When this silicate 
material is found without iron, then they are classified as a Winonaite but 
with/in an iron then they become a silicated iron.

Is this right or am I way off here? There seem to be an increasing amount of 
silicated irons being classified as a Winonaite. So when is a silicated iron 
not a Winonaite and vice-versa?

Thanks,

Jeff
