A bulk analysis of small mm samples of a chondrite might not reflect the bulk analysis of a larger contiguous sample that represents the structure of the entire mass.
 
So, before any conclusions are made it might be best to wait for that bulk analysis made from a larger sample..

Hi,
Just wondered if anyone has any of the 23rd Sept New Orleans strike?

Because amazingly enough I have!!

I have a friend in NO and he recovered some samples from the gutters using a
large magnet. He is a professional geologist at the local uni and has very
kindly sent me a mm-sized fragment that he recovered legitimately! He
hasalso supplied an initial analysis, and he says:

"I got the first batch of data, high Mg-olivine, 32-44 % MgO, 11-16 % FeO,
plus 0.5 % MnO! Rather surprising, a bit high for a meteorite. The
pyroxenes are diopsidic to hgh Mg-pigeonitic. And the plagioclases are
surprisingly Na-rich for a meteorite, over 8% Na2O. A weird meteorite"

Maybe someone can advise me as to the nearest equivalent fall by looking at
this profile.

I am rather proud of it and feel the overwhelming urge to boast about it, as
there is very little in my collection to impress!


Share in my joy please!


very best
