Spangolite

Published online by Cambridge University Press:  14 March 2018

Extract

In the year 1890 Mr. S. L. Penfield described a new copper mineral, to which he gave the name of Spangolite in honour of Mr. Norman Spang, by whom it was first brought to his notice. Of this beautiful mineral only a single specimen was found, and the exact locality has never been ascertained; it belonged to a man living near Tombstone in Arizona, who had gathered together a collection of minerals within a radius of about 200 miles, and it is described by Mr. Penfield as " a rounded mass of impure euprite which was mostly covered with hexagonal crystals of Spangolite associated with a few crystals of azurite and some slender prismatic crystals of a copper mineral containing chlorine, probably atacamite."
