Hi,
Thinking about caliche - as it is mainly calcium carbonate , a wash with
HCl would probably nuke it - however, I have got a 66g lump of Dean's CV3
and it is relatively riddled for the first 0.5cms to 1cm with caliche veins
- I suspect that a dunk in HCl may cause fragments of the meteorite
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
Also, having just bought a 40g slice of
!!!
thanks for the data
