I wondered that too (and don't know the answer). There are a few less striking examples on the slice which show similar 'cracks'.

I won't hesitate to agree with that assessment. Tis a thing of beauty. In the close-up fine web like structures seem to emenate from the circumference. Is this an artifact created in cutting and polishing or it is inherent in the bleaching process?

Mark and List is that an artifact near the midline in the lower 1/4 or is that a perfectly circular armoured condrule?

Other slices show gunmetal blue clasts that look mottled and suspiciously like LL6 or even LL6-7 inclusions and still others show cm-sized dark, featureless inclusions - almost CK-like with tiny nuggets of troilite. Well, when NWA 4522 was offered by Carsten some time ago, I was unable to decide which slice I should take so I purchased four of them and can now enjoy all these features simultaneously :-) Best wishes, Bernd __ Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
