The deposit has been briefly described by Bastinl and certain rare phosphatesfound there have been discussedby palache.? The deposit was first opened during the summers of 1903 and 1904in a for commercial quantities of pollucite. satisiactory quantities were obtained but mining has now ceased. Due to the care with which Mr. Nevel collected all unusual minerals, it was possible to secure a very complete suite for the Harvard Mineralogical Museum. This suite formed the basis for the mineralogical data in this paper. Acxnowr,roGMENTs Thc writer wishes to acknowledge his great indebtedness to Professor Palache whoseconstant assistanceand constructive criti- cism were of the utmost value during the collection of the data and the preparation of this paper. professor palache made a crys- tallographic study of the tourmalines and constructed the figuies given in this paper. To Mr. H. Berman the writer is obligated for much assistance during the laboratory study of the minerals and the mineral se- quence, Mr. H. Butterfield visited and studied the Newry deposit in 1927 and the writer has drawn freely on his unpublished data. 34e 350 TH E AM ERIC A N M I N ERA LOGIST LocarroN lies at an elevation of about 1525 feet above sea level and 4600 feet west of the main highway.

NEW MINERALS It Is Proposed Hereafter to Indicate In.A General Way the Classification of All New Minerals Recoided in This Department
JOURNAL MINERALOGICAL SOCIETY OF AMENICA 63 Dr. Kunz then spoke of the various city localities and the minerals found therein. He stated that the East Side, from 37 to 110 St., probably afforded the most specimens. The various tunnels and their minerals were spoken of. Capt. Miller called attention to the fine collection of Brooklyn Drift Minerals and Rocks in the collection of the Long Island Historical Society. Ife abo mentioned the occurrence of monazite and xenotime crystals, on the Speedway,Harlem River. Dr. Kunz emphasizedthe irnportance of complete records being kept of all finds. Tnou,q,s L Mrr,r,nn, SecretaryPro, Tem. NEW MINERALS It is proposed hereafter to indicate in.a general way the classification of all new minerals recoided in this department.

The meeting place is easily recognized through the Abbott farmhouse on the east side of the road, and the ore hopper and pas ture on the west side. The one mile long dirt road up to the mines was passable by car on July l6. If it has been washed out by October we will arrange for jeeps to ferry those few who are unable to walk to the top of the hill.

The mineral suites from three of these quarries are different and a unique opportunity to study a wide range of pegmatite minerals is available. -

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.
