Journal Article
Structural and chemical study of weishanite, (Au,Ag,Hg), from the Keystone mine, Colorado, USA.
Journal: Mineralogical Magazine
Published: 01 October 2018
Mineralogical Magazine (2018) 82 (5): 1141–1145.
...Luca Bindi; Frank N. Keutsch; Giovanni O. Lepore ABSTRACT Structural data for weishanite, an alloy of Au, Ag and Hg, were collected for the first time from a crystal from the Keystone Mine, Colorado, USA. The structure was solved in the space group P 6 3 / mmc with the unit cell a = 2.9348(8) and c...

Mineralogical Magazine (2023) 87 (6): 819–829.
... of tens of micrometres or less. Application of electron microprobe analysis (EPMA) and limited electron back-scattered diffraction (EBSD) was required to characterise them. These techniques revealed the presence of the approved mineral weishanite (Au–Hg–Ag) and a phase with compositional range Au 2 Hg–Au...
