38Th RMS Program Notes
E.fu\wsoil 'og PROGRAM Thursday Evening, April 14, 2011 PM 4:00-6:00 Cocktails and Snacks – Hospitality Suite 400 (4th Floor) 6:00-7:45 Dinner – Baxter’s 8:00-9:15 THE GUALTERONI COLLECTION: A TIME CAPSULE FROM A CENTURY AGO – Dr. Renato Pagano In 1950, the honorary curator of the Museum of Natural History in Genoa first introduced Dr. Renato Pagano to mineral collecting as a Boy Scout. He has never looked back. He holds a doctorate in electrical engineering and had a distinguished career as an Italian industrialist. His passion for minerals has produced a collection of more than 13,000 specimens, with both systematic and aesthetic subcollections. His wife Adriana shares his passion for minerals and is his partner in collecting and curating. An excellent profile of Renato, Adriana, and their many collections appeared earlier this year in Mineralogical Record (42:41-52). Tonight Dr. Pagano will talk about an historic mineral collection assembled between 1861 and 1908 and recently acquired intact by the Museum of Natural History of Milan. We most warmly welcome Dr. Renato Pagano back to the speakers’ podium. 9:15 Cocktails and snacks in the Hospitality Suite on the 4th floor will be available throughout the rest of the evening. Dealers’ rooms will be open at this time. All of the dealers are located on the 4th floor.

Box 27272, Sharjah, United Arab Emirates Abstract – Brandãoite, [BeAl2(PO4)2(OH)2(H2O)4](H2O), is a new Be Al phosphate mineral from the João Firmino mine, Pomarolli farm region, Divino das Laranjeiras County, Minas Gerais State, Brazil, where it occurs in an albite pocket with other secondary phosphates, including beryllonite, atencioite and zanazziite, in a granitic pegmatite. It occurs as colourless acicular crystals <10 µm wide and <100 µm long that form compact radiating spherical aggregates up to 1.0–1.5 mm across. It is colourless and transparent in single crystals and white in aggregates, has a white streak and a vitreous lustre, is brittle and has conchoidal fracture. Mohs hardness is 6, and the calculated density 3 α β γ is 2.353 g/cm . Brandãoite is biaxial (+), = 1.544, = 1.552 and = 1.568, all ± 0.002; 2Vobs = 69.7(10)° and 2Vcalc = 71.2°. -
Palermo Zanazziite (Pdf)
A Palermo Mineral Identification Search Tom Mortimer Forward: Mineral collectors take great satisfaction in placing accurate labels on their specimens. This article follows my 22 year quest to identify a self-collected Palermo specimen. I have recently narrowed my initial choices to the most plausible species. However my investigation illustrates that even those collectors with access to modern tools of mineral ID such as EDS, they may still be left with ambiguities. This is the forth re-write of this article. My thanks to Jim Nizamoff and Bob Wilken for their most helpful reviews. Background: Locality: Palermo #1 Mine, N. Groton, NH Specimen Size: 2.8 cm specimen Field Collected: Tom Mortimer - 1997 Catalog No.: # 217 Notes: This specimen was in my NH Species Display as fairfieldite for several years. It was visually identified by Bob Whitmore as fairfieldite. I understood that this was the spherical form of fairfieldite referred to in Bob Whitmore's book, The Pegmatite Mines Known as Palermo. The Story: A goal of my New Hampshire mineral species web site and display is to confirm species with analytic testing. This is particularly true for uncommon species and specimens where a visual identification is problematic. A 2017 investigation of NH fairfieldite and messelite revealed that my specimen #217 was not fairfieldite. A first polished grain Energy Dispersive Analysis (EDS) (BC77a – set 6) indicated a Ca, Mg, Fe, phosphate with a Ca:Fe:Mg:P ratio of about 2:1:1.4:5. No Mn was detected, 2+ 2+ essential for fairfieldite. Fairfieldite chemistry is: Ca2(Mn ,Fe )(PO4)2 · 2H2O . -

HAWTHORNES Department of Geological Sciences,University of Manitoba, Winnipeg, Manitoba R3T 2N2, Canada AesrRAcr A hierarchical structural classification is developed for borate minerals, based on the linkage of (BQ) triangles and (BO+) tetrahedra to form FBBs (fundamental building blocks) that polymerize to form the structural unit, a tightly bonded anionic polyhedral array whose excesscharge is baianced by the presenceof large low-valence interstitial cations. Thirty-one minerals, with nineteen distinct structure-types,contain isolated borate polyhedra. Twenty-seven minerals, with twenty-five distinct struc- ture-types, contain finite clusters of borate polyhedra. Ten minerals, with ten distinct structue-types, contain chains of borate polyhedra. Fifteen minerals, with thirteen distinct structue-types, contain sheets of borate polyhedra. Fifteen minerals, with thirteen distinct sEucture-types,contain frameworks of borate polyhedra. It is only the close-packed structures of the isolated- polyhedra class that show significant isotypism Kelwords: borate minerals, crystal sffuctures, structural hierarchy.

Roscherite-Group Minerals from Brazil
■ ■ Roscherite-Group Minerals yÜÉÅ UÜté|Ä Daniel Atencio* and José M.V. Coutinho Instituto de Geociências, Universidade de São Paulo, Rua do Lago, 562, 05508-080 – São Paulo, SP, Brazil. *e-mail: [email protected] Luiz A.D. Menezes Filho Rua Esmeralda, 534 – Prado, 30410-080 - Belo Horizonte, MG, Brazil. INTRODUCTION The three currently recognized members of the roscherite group are roscherite (Mn2+ analog), zanazziite (Mg analog), and greifensteinite (Fe2+ analog). These three species are monoclinic but triclinic variations have also been described (Fanfani et al. 1977, Leavens et al. 1990). Previously reported Brazilian occurrences of roscherite-group minerals include the Sapucaia mine, Lavra do Ênio, Alto Serra Branca, the Córrego Frio pegmatite, the Lavra da Ilha pegmatite, and the Pirineus mine. We report here the following three additional occurrences: the Pomarolli farm, Lavra do Telírio, and São Geraldo do Baixio. We also note the existence of a fourth member of the group, an as-yet undescribed monoclinic Fe3+-dominant species with higher refractive indices. The formulas are as follows, including a possible formula for the new species: Roscherite Ca2Mn5Be4(PO4)6(OH)4 • 6H2O Zanazziite Ca2Mg5Be4(PO4)6(OH)4 • 6H2O 2+ Greifensteinite Ca2Fe 5Be4(PO4)6(OH)4 • 6H2O 3+ 3+ Fe -dominant Ca2Fe 3.33Be4(PO4)6(OH)4 • 6H2O ■ 1 ■ Axis, Volume 1, Number 6 (2005) www.MineralogicalRecord.com ■ ■ THE OCCURRENCES Alto Serra Branca, Pedra Lavrada, Paraíba Unanalyzed “roscherite” was reported by Farias and Silva (1986) from the Alto Serra Branca granite pegmatite, 11 km southwest of Pedra Lavrada, Paraíba state, associated with several other phosphates including triphylite, lithiophilite, amblygonite, tavorite, zwieselite, rockbridgeite, huréaulite, phosphosiderite, variscite, cyrilovite and mitridatite. -
