Re: [meteorite-list] Educational presentations at Tucson?

[Anne Black via Meteorite-list]

Laura,

That is the first I hear of this!
And I was in Tucson 3 weeks in the Innsuites so not all that far from the Pima 
College.
How did you find out about it?

And Michael,
To second what Mike Farmer said, yes I was there 3 weeks but I would not have 
had time for those lectures (even if I had known about them). Also after doing 
that show for some 15 years, it seems that visitors fall in 2 categories: 
either highly knowledgeable collectors who know exactly what they want and who 
came to the Show with a mental list of dealers to see and pieces to look for. 
Or visitors who happen to wander in my room out of curiosity and who know 
nothing about meteorites. Very few in-betweens. 
The first kind would probably not need those presentations, the second kind?  
maybe, but how would they hear about it? online?  on Facebook???  I am sorry 
but I do not have an answer.

Hello All,
  
There was an educational series of lectures during the last Tucson show in in 
the evenings held one of the rooms at the Pima Community College with 2 guests 
speaking per evening. 
  
There were both attendees and online live feeds available for an entrance and 
viewing fee.  These included lectures on minerals, fossils and also meteorites. 
 I watched 5 nights during the show from a FB live feed.  This was held by 
Tucson Gem Shows Educational Lecture Series.  Proceeds go towards establishing 
a scholarship for a local Tucson geology student (or students) attending PCC.

Hi Michael,

I think your idea has merit but Doug points out some good points. What I would 
suggest if you were able to arrange this, first, I'd have presentations and 
talks more during the evenings after dinner time. Second, if you were to have a 
list of topics that were going to be addressed along with a time line, well 
ahead of the Tucson Show, so people could attend areas they were interested in. 
Maybe post the topics a week ahead of time before the show and post them again 
just before and during the show, I think you would get a steady group of people 
that would attend. 

Things like this cost money, but a fee to cover and off set costs would be fine 
as long as it wasn't too much or you would loose people. Perhaps a fee for each 
talk people want to attend. You might also offer some refreshments for a modest 
fee to off set the costs. I'd see if you couldn't get a hotel to donate a room 
for the talks. This could be all or part of the cost of the meeting room.

I wouldn't appreciate dealers making an info commercial but if they gave solid 
science type of program, then fine. I have organized sizable conventions before 
(over 300 attendees) and it can be a lot of work but there is a lot of great 
scientist that are in the area or attend and I am sure that some of them would 
be glad to offer informative talks for the troops during the show. Good luck 
and hope you are able to succeed! Best!

show is a pretty hands on collecting, trading, swapping experience and that's

The particular example I had questions about is the entry for Hart, a Texas

a pretty rare carbonaceous chondrite type and Hart was apparently the only 
meteorite in the U.S. to get that classification.  However, I recently came 
across a scientific paper ("Reclassification of Hart and Northwest Africa 6047: 
Criteria for distinguishing between CV and CK3 chondrites" [3]) that appears to 
make a persuasive case for Hart being reclassified as a CV3. This paper was 
published in 2017, but there is no update yet in the Met Bull entry.

So my questions are:

1) Will the Meteoritical Bulletin database entry for Hart eventually get 
updated to reflect a change in classification?

2) What mechanisms (if any) are in place to keep track of these types of 
reclassifications and make updates? (From what I've seen, there is a mechanism 
for Antarctic meteorites via the Antarctic Meteorite Newsletter. See, for 
example AMN item on reclassifications [4] and subsequent Met Bull database 
entry update [5].)

3) Is there some body that mediates between competing classification claims?  
E.g. what if the original classifier disagrees with a reclassification?

Quick answer. If you go look at NWA 7034 in the Met Bulletin, you can get an 
idea of how the Met. Society, and mostly the Nomenclature Committee work and 
refine a classification as more studies are done. Goodnight. Anne

Re: [meteorite-list] Meteorite reclassification questions

[ALAN RUBIN via Meteorite-list]

When I initially classified Ningqiang, there were no known CKs. We
classified it as CV3 because that was the closest group, but we noted that
its refractory lithophile element abundances didn't match CV that well.
Later, when we defined the CK group, it became obvious that Ningqiang was
more like CK than CV.  Later, upon additional reflection and analyses, we
thought it most likely that Ningqiang was sufficiently different from
normal CKs, that it was probably an ungrouped carbonaceous chondrite that
was closely related to CK and CV.

If you want a meteorite to be reclassified int the Bulletin, you need to
let the folks know (i.e., through Jeff Grossman) that this is warranted and
explain the reasons. Sometimes, the rock will indeed be reclassified and
sometimes it won't. It can be frustrating. I'm not familiar with Hart or
NWA 6047. You could email Tasha Dunn and ask her.

[meteorite-list] lunar meteorite-related: new Apollo 11 film

[Dolores Hill via Meteorite-list]

Greetings Meteorite-List friends and lunar meteorite admirers,

Before we identified lunar meteorites that collided with Earth, the only 
samples of the moon for research came from the Apollo and Luna missions.


_We invite you to enjoy __*Apollo 11*_, a new film premiering this 
Friday at The Loft Cinema in Tucson, Arizona. It contains 
never-before-seen footage from this historic mission to the moon. Watch 
it on the biggest screen in southern Arizona (perhaps all of Arizona?) 
and feel the adventure as you ride along with Neil Armstrong, Buzz 
Aldrin, and Michael Collins. (Be sure to select "screen 1" showtimes). 
See here for more information: https://loftcinema.org/film/apollo-11/


Staff from the Lunar and Planetary Laboratory will greet you before the 
evening showings on Friday and display moon maps made by Gerard Kuiper's 
team that helped determine landing sites and assisted astronauts with 
crater identification. We will also display modern moon globes and a 
disk from the University of Arizona's Bicentennial Moon Tree whose seeds 
traveled to the moon and back on Apollo 14.



In addition, for LPL's _Apollo50 Celebration on July 20, 2019_, we are 
looking for those who worked on some aspect of the Apollo missions. We 
want to hear your story! Contact Maria Schuchardt at 
mari...@lpl.arizona.edu if you would like to share your contribution or 
a family member's contribution.


Best regards,
Dolores Hill

Re: [meteorite-list] Meteorite reclassification questions

[Galactic Stone & Ironworks via Meteorite-list]

Hi Michael,

I am sure someone with more expertise will chime in, but I can think
of two different things that lead to a meteorite being "reclassified".
By "reclassified", I assume you mean being published in the Met
Bulletin. This can happen when there is a change in nomenclature or an
error was found in the original classification write-up.

At one point, all CK meteorites were considered to be part of the CV
clan. This later changed and subsequently many entries in the Met Bull
needed to updated to reflect this fact.

Another example that comes to mind is the infamous Al-Haggounia 001
case. It is officially classified as an aubrite, yet is has been shown
to be an EL3 chondrite. Despite this, the erroneous entry in the Met
Bull remains unchanged - again, maybe someone who has direct
experience with maintaining the Met Bull can chime in on this stuff.

The answer to your third question is likely the Nomenclature Committee.

Best regards,

MikeG

Re: [meteorite-list] Meteorite reclassification questions

[Anne Black via Meteorite-list]

(oops, forgot about plain text)

Quick answer. 

If you go look at NWA 7034 in the Met Bulletin, you can get an idea of how the 
Met. Society, and mostly the Nomenclature Committee work and refine a 
classification as more studies are done.

Goodnight.

Subject: [meteorite-list] Meteorite reclassification questions


 As a newbie, I've come to rely pretty heavily on the Meteoritical Bulletin 
database for information about particular meteorites as well as to look at 
aggregate data for different types.



I've been somewhat surprised to discover that it is not unusual for meteorites 
to get reclassified and I was wondering if anybody could tell me how and under 
what circumstances a Met Bull entry gets updated to reflect new classification 
information.



Ningqiang is a good example of reclassification updates.  The Meteoritical 
Bulletin database entry shows that Ningqiang was originally classified as a 
CV3, per Meteoritical Bulletin #65 (1987) [1]. Then (if I'm interpreting the 
entry correctly) it looks like it was reclassed as a CK3, per the Natural 
History Museum's Catalogue of Meteorites, 5th edition (2000).  And a subsequent 
reclassification as C3-ung came per the 7th edition of MetBase (2006).



The particular example I had questions about is the entry for Hart, a Texas 
meteorite found in 2010 and that was initially classified as a CK3 [2].  CK3 is 
a pretty rare carbonaceous chondrite type and Hart was apparently the only 
meteorite in the U.S. to get that classification.  However, I recently came 
across a scientific paper ("Reclassification of Hart and Northwest Africa 6047: 
Criteria for distinguishing between CV and CK3 chondrites" [3]) that appears to 
make a persuasive case for Hart being reclassified as a CV3. This paper was 
published in 2017, but there is no update yet in the Met Bull entry.



So my questions are:



1) Will the Meteoritical Bulletin database entry for Hart eventually get 
updated to reflect a change in classification?



2) What mechanisms (if any) are in place to keep track of these types of 
reclassifications and make updates? (From what I've seen, there is a mechanism 
for Antarctic meteorites via the Antarctic Meteorite Newsletter. See, for 
example AMN item on reclassifications [4] and subsequent Met Bull database 
entry update [5].)



3) Is there some body that mediates between competing classification claims?  
E.g. what if the original classifier disagrees with a reclassification?
