| Last year at Tucson Carlos Meneses gave me a name for this, but I cannot find it now. Try getting in contact with him.

Rocks, from the look of it in the photos

If it's an ore sample, I recommend the lab at the University of Oruro, in Bolivia.
If XRD is needed, then I use John Attard in California;
if microprobe is needed, then Joy Desor in Germany, or Joan Rosell in Barcelona... |

I found the names:
Daniel Atencio at the University of Sao Paulo and Ricardo Scholz at the University of Duropraiso. If they can't do analyses, they can probably point you to someone who can.
Happy New Year.
