Hi,

Yeah, I noticed on Dave's superb Etherville slice, that there where also
quite a few vesicles in the darker ?melt? pockets some of them quite big
bubbles, what are the implications for this? Does this mean it's just

Dear List members,
Just a quick reminder that we have the 1 kg Amgala auction ending tonight.
The reserve price is low, its a good opportunity to acquire an amazing museum piece
for a
very reasonable price. Free shipping worldwide with Chronopost. For example delivery
in 2
days for the USA.
Hello Anne, Adam, Dave, Mark and List,
quite a few vesicles in the darker ?melt? pockets some of them quite
big bubbles, what are the implications for this? Does this mean it's just
odd impact melt or would you normally expect vesicles on a core-mantle
sample??
My 5.6-gram Estherville slice
Perhaps bubbles = Boyle's law at work.

We were fortunate to meet both Dave McKay and Everett Gibson mentioned in
this article in Tucson a couple of years ago and again at the Lunar and
Planetary Conference in Houston. They are both some of the friendliest
people you would hope to meet.

into several fragments when he removed it from the ground... He told

Hi, all!
Well this is a pretty kettle of fish! Most of the mesosiderites I have seen
are like Estherville, save that I don't recall any with such nice olivine
crystals, where the metallic component is arranged in a substantial web
through the rocky matrix, but is irregular in distribution,
Also Brachina, which was originally thought to
be a chassignite.

Hi All,
Tracy asked:
We already assume that pallasites are from the core-mantle boundaries of
asteroids large enough to have undergone differentiation at one point in
their lives (before being turned into specimens in our collections!)
What other theories for the formation of mesosiderites,
Good afternoon List;
Dunite is one of the mineral groups that are mantle derived here on
Earth, and diamonds are associated with, didn't we discuss diamonds last
week in a different context.
Very small world.
Could there be a chance of diamonds in a dunite asteroid out there
floating around
Ahhh, that makes sense. The only meteorites that have dunite are the ones
that are reliably confirmed to have planetary origins (Martian or Lunar),
and some mesosiderites. Interesting marker on the part of the mesosiderites;
those particular ones must be at least partially of mantle origin,
Hello List,
Since on the topic of dunite or olivine.
Just a km from where I live there are at least two locations
of large dunite outcrops.
Less than 100 km to the south of me there are three valleys
almost composed of just dunites. One is made into a large scale
open pit mine. Farms has been
Wonder if there is a (largely) dunite parent
body floating around the asteroid belt?
If they are floating around out there, the most probable
candidates are M.J. Gaffey's S-type asteroids: His S(I)
subtype asteroids have reflectance spectra indicating

Hello Dave,
Dunite is not very common. It is essentially an olivine rich peridotite.
Such rocks in Wyoming are almost always serpentinized, and are usually
classified as serpentinites.

Dear Listees
As one who has done a bit of geobotanical and remote sensing research in the
Josephine Ophiolite in SW Oregon, I can suggest that in the ultramafic rck of
SW Oregon and NW California, one will find mostly serpentinized peridotites
and occasionally non-serpentinized dunites.
Dear List;
For those wishing to know more about Wyoming minerals, and general
gems/gold/metals/diamond information on line, the last forward post on
dunite with response by W. Dan Hausel, the link to Wyoming Geologic
Survey has some excellent information.

Hi Dave, Dave and List
I have some Washington state dunite. Great stuff. The Twin Sisters dunite is
a nice outcropping and I understand that theres a refractory manufacturer
who mines the dunite there in the Cascades east of Mt Vernon.

It should be $20.00 per gram.
