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


Locality type:Mine
Classification
Species:Serpierite

Serpierite is rare at this site, but a number of samples have been found. The lath-like shape and jagged terminations distinguish them from other blue species here, particularly from linarite (which also is darker blue in color.)
Habit:Lath-like micro-crystals with jagged terminations, in clusters exhibiting both parallel growth and jackstraws.
Colour:Bright medium blue.
Luminescent properties:none
Quality for species:Good crystals or rich for species - important (!)
Abundance at site:Very Rare
Confirmation
Validity:Confirmed
Confirmation Methods:SEM-EDS
