American Mineralogist (1934) 19 (12): 603–604.
..., noticed groups of small, red, acicular crystals floating on drops of native mercury and in some instances lining small vugs of dolomite crystals. Examined under the microscope, these orange-red crystals proved to be montroydite, an orthorhombic mercuric oxide, which heretofore has been reported only from...

..., with >30% Hg 0 . Terlingua is also notable for being the type location for several rare Hg minerals, including Hg chloride (calomel, Hg 2 Cl 2 ), oxide (montroydite, HgO), and mixed sulfate, chlorate, and molybdenate-bearing species. These Hg minerals represent phases that formed under very oxidizing...

..., cinnabar is highly insoluble ( K sp ~10 −53 at 25 °C), whereas eglestonite [(Hg 2 ) 3 Cl 3 O 2 H] and montroydite (HgO) are orders of magnitude more soluble. Thus, when present as cinnabar, Hg is much less bioavailable than when present as eglestonite or montroydite, although cinnabar's solubility can...
