You may jest Rob but I've seen it. ;-)

Not a Pallasite with chondrules as such but pieces of extremely weathered
Huckitta. It almost looks like a weathered (W5) type 3 or 4 impact melt.
They look a bit like chondrules... but they're not. Very, very weird stuff!

Cheers,

Jeff

Hi Ruben,

Congrats on the new Arizona find! What a terrific discovery: metal,
large olivine phenocrysts, and even a lonely chondrule. The presence
of that chondrule would seem, by definition, to rule out an achondrite
classification, although I understand acapulcoites apparently (and
paradoxically) can contain chondrules (e.g. NWA 725, GRA 98028).
But I can't say I've ever heard of an acapulcoite with such large
olivine phenocrysts, so I would be inclined to rule out this
classification.

I guess the riddle to ask is "When does a pallasite have chondrules?"

:D --Rob

Hi all,

On September 24, 2009 I made (what I think will be) one of the most
important Arizona meteorite finds of my life. I found what is probably
a very rare achondrite meteorite. I say probably because no one can
definitively say what type it is just by looking. It is currently
being classified at ASU by Lawrence Garvie ? so we will soon know.

Here is a link

This past weekend ? in an attempt to find more - I put together a team
of top notch meteorite hunters (Mike Miller, Sonny Clary, Stan Wall,
Del Waterbury, Mike Morgan and Myself). Unfortunately, between the
rains and mud we came up empty.

After checking the weather (online) with a very helpful Susan Morrison
we decided that in order to get out of the rain we needed to head
east. Within a sort time we found ourselves in an area in New Mexico
where no finds have been recorded.

We hunted for an hour or two when I spotted Mike Morgan and Del
examining a stone. Sure enough Del had found his first cold find and
it was a very fresh looking meteorite! Mike Morgan was next to find
one and then shortly after I did too.

We think this may prove to be a ?NEW? and very fresh New Mexico Strewn
field. Time will tell as we return to hunt for more of these
beautifully crusted specimens in the weeks to come.

Take a look
