Murdochite
Murdochite is a mineral combining lead and copper oxides with the chemical formula (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.Fahey, Josepf J., (1955) Murdochite, A new Copper Lead Oxide Mineral. American Mineralogist 40, 905-906. 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.http://www.mindat.org/min-2812.html Mindat.org Murdochite was first suggested to be of a cubic structure.Christ, C. L., and Clark, Joan R. (1955) The Crystal Structure of Murdochite. American Mineralogist 40, 907-916. After this suggestion, the term “murdochite-type structure” began to be used when describing a structure that is similar to that of murdochite.Winkler, Björn, Chall ...

Halide Minerals
Halide minerals are those minerals with a dominant halide anion (, , and ). Complex halide minerals may also have polyatomic anions.
