[meteorite-list] Huge Tridimite XL in Gibeon

[Michael L Blood]

Subject: Tridimite Xls in Gibeon Meteorites:
            I have heard of Tridimite Xls occasionally being found in
Gibeon - Tridimite being superheated quartz. Personally, I don't
remember ever seeing any, and, if I did, they were tiny. However,
I recently posted a photo of a specimen on the web so large
it blew my mind. I think  people may enjoy seeing it:

        If you don't already get my Preposts, I think you will enjoy
checking out this huge Xl.
        Best wishes, Michael
