[meteorite-list] Tucson show up and running!

[Michael Farmer via Meteorite-list]

Hello everyone. My room with Jim and Eric is up and running and the best ever. 
Amazing things on display and for sale. I had to leave for a family emergency 
but am dealing with that and will return Sunday evening. Jim can handle all my 
business in my absence. 
Be sure to check it out. Room 184 Hotel City Center. Moritz Karl and Comet shop 
are all right by me so the backside of the hotel has becoming meteorite-row.

I saw this live last night it fell to the ground and was awesome to see. it 
ended its journey in Uwharrie national forest. actually made my cell phone go 
blank was very bright as if night changed to day in a snap but as if we had a 
blue sun it was like looking through a blue filter.. location not disclosed 
until i go look first.. sorry

[meteorite-list] South Carolina bolide on 25 January 2017

[Matson, Rob D. via Meteorite-list]

AMS event 270-2017 generated a sonic boom that was recorded at 9:12:06 UT on
25 January 2017 at seismic station CO.BIRD in Birdtown, Kershaw, SC (34.645 N, 
80.4615 W).
It was also recorded (much less strongly) by N4.Y57A in Sumter, SC (34.017 N, 
80.3915 W)
at 9:14:19 - 2 minutes 13 seconds later. These two seismic stations are 70 km 
apart,
suggesting the terminus was between the two of them and about 40 km closer to
CO.BIRD than to N4.Y57A.    --Rob

[meteorite-list] Dealer?

[Dave via Meteorite-list]

 

 Please delete this if it is inappropriate.

The Kalamazoo Geological and Mineralogical Society is searching for a meteorite 
dealer for our rock and mineral show the end of April. 
Our current dealer has retired and we are looking to replacing him. 
If interested, I can be contacted at stonehouser...@cs.com. and provide you 
with the particulars on the show.
(We are on Facebook at Kalamazoo Rock Club if you would like to look the club 
up.)
Thanks,
David Haas
President, KGMS

Re: [meteorite-list] (no subject)

[MexicoDoug via Meteorite-list]

Thanks Doug,
Got to really dig into this paper to make sense of the conclusion which is only 
speculative and needs 
to be further evaluated for positive confirmation bias and field and lab work 
around the world.  It was 
quite top heavy on analysis which appears well done!

The authors, or maybe it was the press, used the study's 270 kg dissolved 
sample of well-characterized 
"chronostratigraphic" sediments from a Russian deposit in the study which got 
approved for publication 
in the prestigious journal, "Nature", if I read it correctly.  

It would have been more rigorous for my taste if it had been reviewed by MAPS 
editors, or the like, where the focus
 would have been more on interpretation, than on methodology.  Just my opinion, 
as both are important.  
It is an interesting subject - do we call it paleo-meteoritics? Getting any 
paper into Nature deserves congrats
for sure but I expected to be more awed from their editorial staff choices.  
Luckily no one told that to the Alvarez'.

In the end the conclusion is that ordinary chondrites used to be a 
significantly lower proportion of finds, nearly a 
half billion years ago according to the results of their study.  Then 466 mya 
that all changed with the disruption
of an L parent body.  I didn't notice special mention of H- or L-chondrites, so 
the assumption IMO is that that another
event happened recently.  None of this seems remarkably insightful but perhaps 
the authors point of view is 
that here's a smattering of evidence that confirms the idea that the ratios of 
meteorite classes will vary throughout 
geological ages which is nice when things make sense and people begin to 
dimension it with the 'fossil' record.

Kindest wishes
Doug

Hi Doug,

Here is a link to the original paper:

http://www.nature.com/articles/s41550-016-0035

"Our data show that the meteorite flux has varied over geological time as 
asteroid disruptions create new fragment populations that then slowly fade away 
from collisional and dynamical evolution. The current flux favours disruption 
events that are larger, younger and/or highly efficient at delivering material 
to Earth."

Cheers from the “other” Doug,

Doug Ross
