[meteorite-list] RENAMING OF NWA 5435 L4-5 (prov.) TO NWA 3999 (prov.) IN MET. BUL.

[Fabien Kuntz]

Jeff, list, 



NWA 5133 has always been referenced in my database as K092, not K091... About NWA 6435 as prov name that's the last news I obtained from the lab, but indeed saw the status is very different on the database...

Between the data I submitted and what appears on the Bulletin, mistake in maybe 1/4 or 1/5 of the entry (wrong reported TKW, GPS coordinates fall sometimes 1.8km appart of the right find location, wrong main mass owner...). But I checked my email archives, data I submitted was generaly correct !


For other, the classification is just wrong. NWA 5131 is reported as LL7... but is definitively recognized as a CR7 for years now.

Classification accepted before oxygen isotopes, never changed even if requested. Means problem with some collectors, I claim a type when the bulletin say another one...

Problem of delay in meteorite name designation and classification approvement is one thing (for me a nightmare in the case of a carbonaceous from Oman that some listees known, classified, submitted but lost for years now in the process), but mistakes like these drive me crazy. I hunt and document all : GPS coordinates, pictures on the field, pictures at home before cutting, I weight exactly each specimens, cut a type specimen and sometimes provide a thin section, I check and double check a excel file before to send it... and found mistakes at the end, just for an error of copy/paste from my original data. 

I blame no one, work is hard on the lab as on the field, but sometimes...
