Hi All.
Here are a couple small goodies that I picked up at the Denver show for my
collection. As you all know larger Sikhote-alin are coming out few and far
between now. These two are certainly not large (except in ebay description
terms!!!).
Anyway, the first one looks like it
Hi All
Here are some items that I purchased at the Denver Gem Mineral Show last
week. I have added several whole Millbillillies and a few choice Wilunas. Due
to the success of the last Sikhote Alin offering I updated that page and added
some more to it. I also found a cool key chain scale that
Hi ,
I have sold all of the Red lake Meteorites.
Thanks,

Hi Sterling -
With Chiemgau under challenge, the only evidence of
heavy elements in comets that I can easily point to is
the increased iridium at the KT boundary.
I can't really comment on metals in carbonaceous
chondrite meteorites, and right now I would be most
interested in data from others
Hi Doug, list
Planet pairs? Interesting to consider: how about
Mars/Artemis. At least we have plenty of samples to
examine.
good hunting,
Ed

Hi, E.P.,
The truth is we really don't know what comets
and asteroids actually are, or whether there's a real
distinction between them, or if they are just keywords
derived (mistakenly) from the two extremes of a
continuous spectrum of bodies with every intermediate
state fully represented.
Hi Sterling:
Not a bad summary. However, do not know where you got the heated above 50
absolute. Much too low. Just being in an orbit that takes them near the Earth
would warm them up to 100 c or so. Some clearly have not been heated much
above that, but at the same time, since they contain
Hi Stirling, list,
Thanks much for your excellent carbonaceous summary,
Stirling. I lost all the subclasses in my stroke, and
your note contains exactly what I needed to recall.
(Of course, a hands on reacquaintance with all the
types will be even better, and I hope to make one
soon.)
Again
Hi, Larry, List, E.P.
Just another brain-slip; should read 50 degrees C!
Hydration commences as nebular temperatures drop
below 120 degree C. Yeah, that's a warm and cuddly
50 C, not 50 K. Brr... At low pressures that's steam,
not water, down to 160-165 K. after which it's ice.
Like Mars, no

Hi Ed,
Of course, SW3 is likely to provide us with some samples,
certainly by 2022.
Perhaps I'm reading too much into your posts, but several times in
recent weeks you've mentioned the 2022 encounter with the
73P/Schwassmann-Wachmann cometary debris stream as if it
will be a certain,
