Thanks

I don't see the Mn percent. That is needed to get an Fe/Mn ratio.

a man have send me some pictures of a dozen stones and asked me wich types of meteorites could be.
I answered that for me those materials are terrestrial.
But he tell me that for sure the stones are lunar meteorites :) He has send me this analysis for proving the lunar origin of the stones.
I'm not able to understand this data, please someone could take a look and tell me if this material could be terrestrial or extra-terrestrial.
No other analysis was done on the stones. I guess that without an oxigen isotopes abundance ratio is impossible to identify a lunar rock, isn't?
Method LF200
SiO2 47.45%
Al2O3 19.42%
Fe2O3 9.73%
MgO 10.16%
CaO 8.95%
Na2O 1.75%
K2O 0.79%
TiO2 0.29%
P2O5 0.08%
Cr2O3 0.01%
Ba 110ppm
Ni 121ppm
Sc 7ppm
I Have also a detailed list of trace elements.
This man tell me that the presence of K2O and P2O5 confirm the extra-terrestrial origin of the rocks.
Thanks a lot in advance!
