Hello All.
That is a
beautiful individual. Dalgaranga is a very nice meteorite and very stable. I
think it is by far my favorite meso. I decided to quickly put up a picture of
one of the larger pieces of dalgaranga that we have in our personal collection.

Dalgaranga Mesosiderite
Hi
folks,
during my meteorite travels in Chicago last week, I picked up a great looking
Australian mesosiderite individual named Dalgaranga, and was reliably informed
by the curator that "this is the only metallic specimen of Dalgaranga in
existence", with all the remaining 10kg being shale and completely
oxidised mesosiderite. If that's the case, I'm well pleased to be the present
owner, but does anyone know if that's so, or of any other metallic Dalgaranga
specimens out there?
I've linked through to some pictures below that I thought you might like to
see. It's an oriented specimen with fine flow lines over the
"dome"...the rollover lip is just about there, but has suffered from
weathering somewhat. The backside obviously once contained silicate inclusions,
but these have either weathered out to leave pockets, or simply didn't survive
being torn off the larger mass in flight. David Weir suggested to me that this
mostly iron individual was once a metallic nodule, ripped away from it's
surrounding stony matrix in flight, and it's certainly looking that way.
I ground a small corner this afternoon and etched the polished face to reveal a
very fine Widmanstatten pattern, similar to the figures which appear on the
metal blebs in my Estherville slice, plus a couple of tiny silicate inclusions.
Here's the pictures.....enjoy! :-)

By the way, I loved Chicago and even managed to catch a Cubs game at Wrigley
Field....I made it as far as the 7th Innings Stretch, but didn't know the
lyrics to "take me out to the ball game", much to everyone's relief!
Cheers,
