This specimen came out of the Greenbank Collection (label included) and is noted to have been found in 1971. The Lyndsay Greenbank collection was exceptional enough to warrant its own Mineralogical Record suppliment (Jan-Feb 2010). Most of the best campyllites were found in the 19th century, but Lindsay and friends were able to sort out a small find in the early 1970’s. This one has fabulous color contrast from the black (goethite?) just under the yellow-orange primatic clusters.
Locality: Dry Gil Mine, Caldbeck Fells, Cumbria, England
Composition: Lead arsenate chloride
