Murdochite on Quartz

Wikipedia:  "PbCu6O8−x(Cl,Br)2x(x ≤ 0.5),  It was first discovered in 1953 in the Mammoth-Saint Anthony Mine in Pinal County, Arizona by Percy W. Porter, a mining engineer who handpicked a 401.5-mg sample.  Porter would later submit for analysis and it was then that Fred A. Hildebrand suggested that the sample was a new mineral after taking a powder x-ray picture.

It was named for Joseph Murdoch (1890–1973), American mineralogist.  Murdochite was first suggested to be of a cubic structure. After this suggestion, the term “murdochite-type structure” began to be used when describing a structure that is similar to that of murdochite.  Murdochite was later found to be octahedral.  The mineral murdochite is named after Joseph Murdoch, who was once a professor of geology at the University of California, Los Angeles and a past president of the Mineralogical Society of America."
