Hi List,

thanks a lot for all the kind words about the finally classified ungrouped iron meteorite.

The Meteorite was purchased in 2005 at the Munich mineral fair, the TKW is 726g.

Here are the test results:

: Bulk Composition: INAA data (J. Duke, UAb): Ni = 11.54 ? 0.03 wt%, Co = 0.509 ? 0.003 wt%, Ga = 35.8 ? 0.4 ?g/g, Ge = 28 ? 4 ?g/g, Ir = 0.196 ? 0.008 ?g/g, Au = 1.04 ? 0.02 ?g/g, As = 13.0 ? 0.2 ?g/g, Cu = 307 ? 23 ?g/g, Cr = 32 ? 5 ?g/g (uncertainties 1?, 68% confidence level), W ? 0.27 ?g/g, Re ? 0.05 ?g/g. Although Ni, Ga and Ge concentrations are similar to the IAB-sLM/sLH group, the Au concentration is well below the minimum 1.3 ug/g required to consider it part of the IAB complex.

I don't really know if I'm already allowed to public this details, but I hope it will be fine

The picture from RFSPOD shows no meteoritic structure but the light angle gives the best sight to the Graphite inclusions

I will show some more pictures, please feel free to take a look if interested:

This is no AD, I'm sold out.
Thanks to Chris Herd for classification.
Thanks to the Hupe Brothers for the hint where to classify.

Best greetings

(and special thanks to my friend Koppli from Bavaria)

Hello Bernd, and other happy owners of NWA 5804,

Congrats on your nice score, Bernd. Do you have a close-up of rosettes? What
is the TKW of 5804? Truly a crazily-impressive meteorite!

Best regards,
Greg
