[meteorite-list] caliche cleaning and Parnallee question

[bernd.pauli at paulinet.de]

Dave and List,

Dave, you also used to collect minerals (or still do). Remember how ugly
an amethyst looks after a wash with HCL? Instead of risking fragments
to break away or having other mineral constuents dissolved, I'd rather
leave some caliche

Congratulations!

Yes, I can confirm: LL3.6, brecciated; gas-rich; unequilibrated;
microgabbro clasts - some people classified it as an LL3.7 *

and chondrule fragments in LL3 chondrites: Implications for parent-body
fragmentation of chondrules (MAPS 37-10, 2002, 1361-1376).
