Formula:
MgMn2+4(Fe2+0.5Al3+0.5)4Zn4(PO4)8(OH)4(H2O)20
Crystal System:
Monoclinic
Name:
The species is named in honour of the late James (Jim) Anthony Ferraiolo (May 14, 1947-February 6, 2014). The mineral is pronounced /fe..(r) i: ‘Ou lOu ait/. Jim worked as scientific assistant at the American Museum of Natural History (AMNH) from April 1978 until August 1982 and also as transaction coordinator at the Smithsonian Institution’s Museum of Natural History from September 1982 until April 1985. He was best known for his publication A Systematic Classification of Nonsilicate Minerals (Bulletin 172 of the AMNH, 1982), which was widely used in Museum collections, as a basis for collection classification and organisation (e.g. Museums Victoria, Australia). Recently, Jim was a member of the IMA CNMNC subcommittee for mineral group nomenclature and the subcommittee on unnamed minerals. Jim also spent more than a decade as a manager with mindat.org and was instrumental in publishing the description of ferrolaueite (Ferraiolo, 2012; Segeler et al., 2012).
