On Scorzalite from the Angarf-Sud Pegmatite, Zenaga Plain, Anti-Atlas, Morocco
Spec. Issue: r Fortschr. 52 IMA-Papers 9th Meeting 285 - 291 Stuugan Miner. Berlin· Regensburg 1974 December 1975 L-- On scorzalite from the Angarf-Sud pegmatite, Zenaga Plain, Anti-Atlas, Morocco Andre.M.thieu Fransolet* With 2 tables Abrtract: Scolzalite occurs frequently but not abundantly in the phosphate minerals from the AngaIf Sud Precambrian pegmatite Qutcropping in Zenaga Plain, Anti-Atlas. Morocco. Scorzalite is characterized by a determination of the ratio Fe2 +/ Mg. The value obtained for the ratio FeH/(Fe1+ + Mg) is 0.54. The unit cell dimensions are also given. In the Angarf-Sud pegmatite. the phosphate nodules are zoned. A core of gray triphylite, widely replaced by green alluaudite, is fringed by reddish fine-grained apatite. The more important secondary phosphate minerals are: melonjosephite, barbosalHe, tavorite, lipsco mbite, mitridatite, and rock bridgeite. If muscovite occurs in this asseJIlbiage, it is systematically accompanied by scorzaiite and fringed by apatite. Scorzalite replaces muscovite and is inserted in its cleavage. It seems that scorzalite forms under a low oxygen fugacity, more or less simultaneously with Mg triphylite. The so lution, rich in P, Fe2 + and with a little Mg, reacts with mica which provides AI; Si02 and K are released. It is not necessary to evoke a metasomatic process to explain the presence of AL Introduction Minerals of the lazulite MgAI,(PO.), (OH), - scorzalite FeAI, (PO.), (OH), isomor· phous series described by Pecora& Fahey (1950), occur rather frequently in pegmatites but they are scarcely abundant. Systematic study of phosphates from Precambrian pegmatites injected in micaschists and gneiss in Zenaga Plain, Anti-Atlas, Morocco, has revealed the occurrence of a mineral belonging to this series in the Angarf·Sud pegmatite. -
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. -

A Specific Gravity Index for Minerats
A SPECIFICGRAVITY INDEX FOR MINERATS c. A. MURSKyI ern R. M. THOMPSON, Un'fuersityof Bri.ti,sh Col,umb,in,Voncouver, Canad,a This work was undertaken in order to provide a practical, and as far as possible,a complete list of specific gravities of minerals. An accurate speciflc cravity determination can usually be made quickly and this information when combined with other physical properties commonly leads to rapid mineral identification. Early complete but now outdated specific gravity lists are those of Miers given in his mineralogy textbook (1902),and Spencer(M,i,n. Mag.,2!, pp. 382-865,I}ZZ). A more recent list by Hurlbut (Dana's Manuatr of M,i,neral,ogy,LgE2) is incomplete and others are limited to rock forming minerals,Trdger (Tabel,l,enntr-optischen Best'i,mmungd,er geste,i,nsb.ildend,en M,ineral,e, 1952) and Morey (Encycto- ped,iaof Cherni,cal,Technol,ogy, Vol. 12, 19b4). In his mineral identification tables, smith (rd,entifi,cati,onand. qual,itatioe cherai,cal,anal,ys'i,s of mineral,s,second edition, New york, 19bB) groups minerals on the basis of specificgravity but in each of the twelve groups the minerals are listed in order of decreasinghardness. The present work should not be regarded as an index of all known minerals as the specificgravities of many minerals are unknown or known only approximately and are omitted from the current list. The list, in order of increasing specific gravity, includes all minerals without regard to other physical properties or to chemical composition. The designation I or II after the name indicates that the mineral falls in the classesof minerals describedin Dana Systemof M'ineralogyEdition 7, volume I (Native elements, sulphides, oxides, etc.) or II (Halides, carbonates, etc.) (L944 and 1951). -
