Very good question MikeG! I look forward to a expert in Geology or Petrology
and or a meteoricist that can explain this in terms that will resolve this
oxidized/non-oxidized state or better yet "to be or not to be, that is the
question" !!

Subject: Re: [meteorite-list] Hoba shale or not shale?
Hi Folks,
I have seen shale or oxide fragments that had unoxidized metal inside
them when cut. From the outside, the pieces resembled shale, but the
interior was unoxidized iron or it had a "core" area with shiny metal
in it.
So, given such a specimen, is it still considered "shale" or "oxide"
if there is unoxidized metal inside it? What litmus test is used to
determine this? If the metal can be etched, is it considered "iron"
and not "shale"? If so, a way to solve the mystery is to etch the
shiny portion and see if it yields a widmanstatten pattern.
Best regards,
MikeG

Very interesting Don, and thank you for posting this response from
Zsolt.
I will have to disagree with him on one thing, he wrote: "When I have
bought this piece from Anne Black she didnt mentioned me that it is
shale." That is not correct, it is clearly listed as "Shale" on my
website, on the Old Collection page (
http://www.impactika.com/OldIRON.htm ), in fact it is still there, here
is a copy of that listing:
Hoba Namibia 1920 Ataxite C. Anger Slice-Shale 65.389 76 x 33 x 13
$995.00
I would guess that Zsolt, being very new at this, did not notice or did
not know the difference.

Hi Zsolt. Reason I ask is that I know that trying to find some real
actual
Hoba cut from the meteorite is very hard to acquire and very very
expensive. Even today the shale alone is getting difficult to
acquire. I
acquired a 3+ gram polished piece many years ago from Rob Elliott and
the
shale had lots of nice metal inside (still in my collection and can
be
seen here: http://www.ctreasurescwonders.com/meteorite_collection.html
*
But it is still shale and no where near the value of an actual piece
off
the Hoba meteorite (metal). It appears that yours resembles shale but
only
Anne Black who you purchased from can truly confirm this. The outside
appearance of your piece listed on eBay resembles mine from Rob
Elliott.
Again even the shale is hard to acquire...been quite a few years
since I
seen much available until your post. Here is a neat site to check out
about the Hoba and price.

Hope this helps.

Dear Don!
When I have bought this piece from Anne Black she didnt mentioned me
that
it is shale.
Very interesting thing, beceause when I have cutted it it looks like
me
metal shine inside after polishing.
Really was some spot, area of the surface in brown but was metal-gray
area
also.
My bigger piece has content two polished sides and this also has got
structuce and color.
Do you think that there is a 25-30 mm thick shale? Not too wider for
the
shale?
Best Regards!
