Discussion is good, I am glad to see Katol finally in the bulletin no matter
what it is. Thanks for your hard work Dr. Garvie.

Hi Mike and all!
Can't tell by looking at it if it's all metal. If it is predominently
metal (by a large %) and the olivines and such match that of Katol, then
this would be an L-Metalwould it not?

It was bought on the spot from the finders as they lined up to sell the

It is Katol:) Central India is not Morocco with every person having a box of
meteorites to sell.
It is almost completely iron, with perhaps 5% silicates.

Then it should have it's own classification! If it's 95% metal.
Just my opinion.
Do we classify falls or meteorites?
Seems we loose by classifying falls.

Since the iron was found with other fresh Katol stony pieces and some of the
stony matrix is clearly visible on the outside of the iron, I see no reason
to even consider cutting it to get a separate name. That is one nice thing
of the iron being collected within a couple days of the fall, and
Two things:
Many meteorites are heterogeneous. When we say Katol is L6 or NWA 869
is L3-6 or Almahata Sitta is an anomalous urelite, these are collective
terms. Katol refers to everything that fell that day in India. It
has been classified as L6. However, it is possible (and for Almahata
Great discussion...Jeff, you preempted exactly what I was thinking...I
would think such data added to classifications showing details of
unusual lithologies and individuals within the general classification
would be greatly appreciated by all. The variations within falls and
finds always fascinate
Hi Greg and all,
I would not suggest another name nor would I suggest it's a different
fall. However I would suggest a numbering schema that maybe followed a
find sequence. Katol 001, Katol 005, etc.
I say that because if stuff is never studied...ie classifiedwe just
will never know
It would be great if that were done at time of fall like for Sutter's Mill or
Portales Valley. Katol was impossible since it was being collected by locals
and most disappeared into the black hole of Calcutta.

Hi Jim,
I wouldn't call it lazy science, but I agree with a numbering system when
possible, but when there are several people from around the world involved
in a fall collecting stones, it can be impossible to get everyone to go
along with the numbering system. Take Chelyabinsk for instance,
Hello Jeff and Graham,
Exactly.but a step further. I would suggest going further than just
saying what the lithology is.
That was done in this case in the write up.
Okay, so we have as an example Katol #4(?). If you say it has a metal
rich lithologywhat is it?
Everything past that
Hi MikeG and All:
The iron might be from L6 if it turns out that the few silicates in it
(olivine and pyroxenes) have L6 geochem. You see that in the H-metal
from Yucca. Of course large metal masses are probably not as commonly
associated with L. Also if you had oxygen isotopes of the silicate
Hi Greg,
The find order is not necessarily important at all to
science.although I think we all would agree that would be nice.
That's a hunter thing that does not mean much to science.
Field names and numbers are often in the bulletin comments if provided
during the submittable process.
Carl, you you suggesting this might be from different fall? I was there less
than two weeks after the fall. I bought pieces as they were being found right
in front of us. When we showed up with cash the whole village ran around
picking up stones in 52 degree C (120f) heat. There were stones
It would probably be best not to use a lithologic term in a numbering
scheme. Some specimens may defy such a descriptor, and in other cases
it may simply be hard to tell what it is at the time of numbering. And
it would really be good not to use numbers in the same format as dense
collection
I did it for the Cali Colombia fall as well. It is easy to do with low number
fall and one person taking charge.
To this day we don't know where the Katol stones in India are. The large Thika
stone which was taken by the military in Kenya, vanished. We don't even know
the weight of that stone.
Hi Carl,
Spot on!
Question: How much material is required for the oxygen isotope testing???
When we were working on the H-Metal, the ICPMS-LA (Herd) tests completed
on the last one used less than 100 milli-grams.
And previous INAA (Actlabs) testing used 100 milli-grams. And, as you
know
I am not arguing with Laurence, the photos of the thin sections, the oxygen
isotope data seems clear.
I am simply showing there is a little more going on with Katol than common (l6).
You can examine the piece in Tucson when you come down for the show.
I think you'll like it.

It is one of the prettiest meteorite pieces I've ever seen, it isn't going to
be drilled, cored, cut, slabbed, dipped in acid or melted! The other 4 pieces
were sold (Europe I think) let them chop theirs up:)

Mike,
Given the wide range of lithologies we are hearing about, all I am
saying it might be interesting to test the multiple lithologies and
confirm what you are saying. I am not suggesting anything about
multiple bodies or not, I don't have an opinion. I am simply
describing how you could
Some comments that have been made suggest no chondrules, yet there they
are in the BSE images. Laurence does give their sizes in the write
up and they tend to be really small (200 - 700 um), but not really
uncommon. Because of their size, could that be why
some are missing them when they look

Jim,
For one oxygen isotope analysis, I need way less - 1 mg is sufficient. If
there were pieces of silicate sticking out on Mike's sample, along the
margin of the cut side, maybe these could just be clipped/broken off?

Great info. I am sure I will be talking to you soon on a project I am

I can understand why Mike is not going to touch his sample! LOL!
Maybe one of the other collectors will come forward with one of the
other metal specimens!

Thank you Greg.
Yes, all the pieces of Almahata Sitta sold by either Siegfried Haberer
or myself carry the number of the specimen it was cut from. And that is
the number assigned to that fragment by Addi Bischoff.
Example:

MS-174 - Chondrite EL6

From a collector's point of view could I suggest that readers of the
Metlist check their Ebay listings for Katol and revise them as necessary?
Currently all listings still seem to refer to it as probably a rare
ungrouped achondrite (or similar description) but that is no longer
true - unless
Katol is a prime example of why people should avoid self-pairings and
hand-classifications. One (or a dozen) hand samples may not tell the
whole story, and even experienced eyes can be fooled.
For all appearances, Katol may have looked like an OC, an achondrite,
an iron, a stony-iron, or a slag.
