Crocoite from USA
N7N-6YWCrocoite PbCr6+O4
Butte Mine, Black Butte, Gillespie, Maricopa County, Arizona, USAFragmented crystal of crocoite on a specimen I purchased at the 2013 Tucson City Center Show, ex-Huestis Collection. FOV is about 3 mm in length. Child photos show the back side of the specimen with the breakage surface, and a scan of the catalog card accompanying the specimen. It shows an EDS analysis and indicates that it was collected in August of 1984, possibly by Dave Shannon.

Black Butte prospect, Yavapai County, Arizona, USAField of View: 3.5 mm
Crocoite (orange) with Phoenicochroite (red) from the Black Butte claim. 3.5mm field of view. Confirmed by Raman spectroscopy, July 2013. This specimen was labeled "Lead Minerals" in the collection of Arthur Flagg, who originally reported the Crocoite from this locality in 1948. It is the only crystalline Crocoite I've seen from Arizona. Also in association on the specimen is vanadinite, mimetite, and descloizite.
