Hello List
Tooday I have cut some of my new eucrites for samples to thin sections. I 
always like to know what I have, but this time little stones make me fool 
again. I ask You for help, to recognize what this little suc**** are. Since 
they are very small, I think that make classification is not a good idea if 
they are chondrites only.

To be honest, when I look at them I know, they must be chondrites, there is 
no other possibility, but from the other side, one part of me telling me 
that maybe they are achondrites ? I just cant decide myself.

First one is nice fresh specimen that I was sure its eucrite. It looks very 
similar to other eucrites I received. Only one thing make me think about it. 
It was magnetic like normall L chondrite. So when I cut this specimen it 
still look like eucrite except high content of iron, yes like L chondrite. I 
dont know, really.
My idea is L or LL6 highly shocked/brecciated chondrite or eucrite with lots 
of iron.

Second one was more strange than first one. From outside crust was sand 
blasted. On broken surface if looks like CO and smell like best perfumes 
(amazing smell). After first cut's the only idea I got is that I have 
howardite. Yes right, all its correct except this iron. Again there was too 
much iron for achondrite, so this must be chondrite, but...... I not feel 
confident about this.
