Dullx Department of Mineral Sciences Smithsonian lnstitution, Washington, D. C. 20560 Abstract The manganesehumites, (alleghanyite, manganhumite, and sonolite),together with some Mn-bearing samplesof the Mg-humites,and the related phasesleucophoenicite and jerry- gibbsite,from the orebodiesat Franklin and SterlingHill, New Jersey,are describedtogether with analytical data. Solid solution betweenhumite and manganhumiteis at least partially continuous. Expected Mn/Mg solid solutions between alleghanyiteand chondrodite, and betweensonolite and clinohumite, are discontinuous; they are interrupted by apparently orderedphases. In all cases,the possibleorderings involve Zn as well as Mn and Mg. There are no Mn end-membersof the manganesehumites at this locality. Manganeseis apparently restricted in leucophoenicite(5.42-6.63 Mn per 7 octahedral cations) and in jerrygibbsite (7.79-8.02Mn per 9 octahedralcations). Calcium is common to both leucophoeniciteand jerrygibbsite,but among the Mn-humites,only sonoliteaccepts appreciable Ca (0.65Ca per 9 octahedralcations). There is a "threshold" level ofzinc in all studiedsamples; this "threshold" levelis a constantfor leucophoenicite1-9.3 Znper 3 Si)and alleghanyite(-O.2Zn per 2 Si). No samplesof leucophoeniciteor jerrygibbsite were found to be Zn-ftee,suggesting either that Zn is required for their stability, or that these two phasesmight not be stable as end-members.Fluorine is present in all the Mn-humites and is proportional to the Mg- content,but is absentin leucophoeniciteand jerrygibbsite. Introduction humite speciesoccur there; the Mg-humites occur in the The magnesiumhumite species(norbergite, chondrodite, host Franklin Marble for the most part, and the Mn- humite, and clinohumite) have been well-studiedand re- humites in the orebodiesthemselves. -

TEPHROITE from FRANKLIN, NEW JERSEY* Connbrrus S. Hunrsur
THE AMERICAN MINERALOGIST, VOL 46, MAY_JUNE, 1961 TEPHROITE FROM FRANKLIN, NEW JERSEY* ConNBrrus S. Hunrsur, Jn., Departmentof Mineralogy, Harvard, Uniaersity. Assrnlcr A study of tephroite specimens from Franklin and Sterling Hill, New Jersey showed in all of them the presence of thin sheets of willemite believed to be a product of exsolution. .fhese sheets are oriented parallel to the {100} and [010] planes of tephroite with the o and r axes of tephroite and willemite parallel. It is believed that Iittle zinc remains in the tephroite structure and that much of it reported in chemical analyses has been con- tributed by intergrown u'illemite. This conclusion is supported by experiments syn- thesizing tephroite. The indices of refraction and d spacing of {130} vary as would be expected with changes in amounts of MgO, FeO and CaO. INrnooucrroN 'fephroite, Mn2SiO4,a member of the olivine group, was describedas a new mineral from SterlingHill by Breithaupt in 1823.A chemicalanal- ysis of the original material was published by Brush (1864) together with severaladditional chemical analysesof tephroite made by others. These analysesreport ZnO in varying amounts which Brush attributed to invariably associatedzincite. Palache (1937) did not agree with Brush and stated " . that the molecularratios in someanalyses more nearly satisfy the orthosilicateformula when zinc is regardedas essen- tially a part of the mineral rather than as a constituent of mechanical inclusions." The present study was undertaken for the purpose of in- vestigatingthe variations in the propertiesof tephroite with changesin chemical composition, particularly the effect of zinc. Relationships were not expectedto be simplefor analysesshow, in addition to ZnO, variable amounts of MgO, FeO, and CaO. -
