Meneghinite

This page is currently not sponsored. Click here to sponsor this page.
Giuseppe G.A. Meneghini
Formula:
Pb13CuSb7S24
Cu content may be variable.
System:
Orthorhombic
Colour:
Blackish lead-gray
Hardness:
Name:
Named in 1852 by C. Bechí in honor of Giuseppe Giovanni Antonio Meneghini (30 July 1811, Padua, Italy – 29 January 1889, Pisa, Italy), who first discovered the species. He was an Italian botanist, geologist and paleontologist, and the professor of geology at the University of Pisa.
Synthetic meneghinite may be Cu-free but is much less stable by comparison to Cu-bearing meneghinite.

May occur in intimate intergrowths with boulangerite.
