[meteorite-list] unusual crystalline structure found in NWA --your thoughts please

[jim_brady611 at o2.co.uk]

Hi list
      Jason Borst (http://www.opalandjasper.com) who cuts my larger 
specimens has encountered an unusual crystal structure today in an 
otherwise ordinary looking NWA.

Reminds me of a barred olivine chondrule except of course they aren't 
contained within a chondrule.And it's likely not olivine.

I've uploaded a couple of shots for your perusal.I can't recall seeing 
such a structure before in a meteorite.Interested in thoughts and 
references please.
Many thanks
Jim
