Dear List Members,

I just received an email from Dr. Bunch, there was an error in the lab. Here 
is part of his email:

Dr. Bunch's reply:
"Yes there is a mistake. Your section number is RHH4 and was read as PHH4, 
the data of which is ET's CO3.5. Yours is an R3.8. ________complied the data 
before I left and I did not double check it. ---

R3.8     S1            W3            Fa39.3 ± 1.2; FeO/MnO = 72-76  (we 
started to use this constraint which is foolproof in identifying some 
carbonaceous chondrites, don't need O2 data anymore). We have used our 
hundreds of analyses to provide the following FeO/MnO ranges: R = 68-90; CK, 
100 - 130; CO, 110- 150; CV> 140). Some overlap but other compositional 
characteristics overcome the minor overlap of CK and CO, which do not look 
the same anyhow.

I don't know who said that it looked like (NWA)3146, many Rs do but they are 
not paired with (NWA)3146...
Sorry about the mistake and thank you for pointing it out."



Thank you Christian, Marcin and all who brought attention to this mistake. 
It just shows that when we work together, good things happen. I have 
corrected the current auctions on eBay to reflect the R3.8 classification 
and have notified the two members who purchased some using "Buy it Now".



Now, I wonder if crow tastes good with mustard...
