Hemimorphite from
Mascot Mine, Gorham, Coos County, New Hampshire, USA


Locality type:Mine
Classification
Species:Hemimorphite
Formula:Zn4Si2O7(OH)2 · H2O
Comments:Easily mistaken for cerussite or aragonite here (samples are probably overlooked) but has a different habit and morphology that can be seen upon careful examination. The stouter prismatic crystals with a nearly square cross-section are decidely different from the other species' habits. An acid test using 20% HCl showed that both the aragonite and cerussite dissolved, while the hemimorphite did not.
Habit:Micro-crystals in mats, jackstraw clusters, and radiating sprays of acicular to thin prismatic crystals; more rarely as single thin to stout micro-crystals with a nearly square cross-section.
Colour:Milky white to clear.
Luminescent properties:none
Abundance at site:Very Rare
Confirmation
Validity:Confirmed
Confirmation Methods:Wet Chemical
