I tried the allertest on a few known chondrites and they did not show positive, maybe the allertest I have is bunk. I tried it on a few H chondrites and it not once tested positive. I have had it for a long time, maybe it is too old, I'm not sure, but it didnt work. I'll have to order some more and try it again.. Best, Joe K

I have had the same results. Fe Ni will test positive evey time. Having said that , there is magnetite on Mars right? Good luck.
