The structure and spectral properties of two copper bearing 14 xocomecatlite and tlapallite are compared with an iron bearing rodalquilarite mineral. 15 Two prominent bands observed at 9855 and 9015 cm-1 are 16 2 2 2 2 2+ 17 assigned to B1g → B2g and B1g → A1g transitions of Cu ion in xocomecatlite. 18 19 The cause of spectral distortion is the result of many cations of Ca, Pb, Cu and Zn the 20 in tlapallite mineral structure. Rodalquilarite is characterised by ferric ion absorption 21 in the range 12300-8800 cm-1. 22 Three water vibrational overtones are observed in xocomecatlite at 7140, 7075 23 and 6935 cm-1 where as in tlapallite bands are shifted to low wavenumbers at 7135, 24 7080 and 6830 cm-1. The complexity of rodalquilarite spectrum increases with more 25 number of overlapping bands in the near-infrared.

  • Metamorphism of Sedimentary Manganese Deposits
    Acta Mineralogica-Petrographica, Szeged, XX/2, 325—336, 1972. METAMORPHISM OF SEDIMENTARY MANGANESE DEPOSITS SUPRIYA ROY ABSTRACT: Metamorphosed sedimentary deposits of manganese occur extensively in India, Brazil, U. S. A., Australia, New Zealand, U. S. S. R., West and South West Africa, Madagascar and Japan. Different mineral-assemblages have been recorded from these deposits which may be classi- fied into oxide, carbonate, silicate and silicate-carbonate formations. The oxide formations are represented by lower oxides (braunite, bixbyite, hollandite, hausmannite, jacobsite, vredenburgite •etc.), the carbonate formations by rhodochrosite, kutnahorite, manganoan calcite etc., the silicate formations by spessartite, rhodonite, manganiferous amphiboles and pyroxenes, manganophyllite, piedmontite etc. and the silicate-carbonate formations by rhodochrosite, rhodonite, tephroite, spessartite etc. Pétrographie and phase-equilibia data indicate that the original bulk composition in the sediments, the reactions during metamorphism (contact and regional and the variations and effect of 02, C02, etc. with rise of temperature, control the mineralogy of the metamorphosed manga- nese formations. The general trend of formation and transformation of mineral phases in oxide, carbonate, silicate and silicate-carbonate formations during regional and contact metamorphism has, thus, been established. Sedimentary manganese formations, later modified by regional or contact metamorphism, have been reported from different parts of the world. The most important among such deposits occur in India, Brazil, U.S.A., U.S.S.R., Ghana, South and South West Africa, Madagascar, Australia, New Zealand, Great Britain, Japan etc. An attempt will be made to summarize the pertinent data on these metamorphosed sedimentary formations so as to establish the role of original bulk composition of the sediments, transformation and reaction of phases at ele- vated temperature and varying oxygen and carbon dioxide fugacities in determin- ing the mineral assemblages in these deposits.

Few studies are available concerning the distribution and mineralization of Ag, restricting further resource exploration. In this study, detailed mineralogy, chronology, and geochemistry are examined with the aim of revealing Ag occurrence and its associated primary base-metal and supergene mineralization. Results show that manganite and romanèchite are the major Ag-bearing minerals. Cassiterite from the Mn–Ag ores yielded a U–Pb age of 436 17 Ma, consistent with ± the Caledonian age of the Nanwenhe granitic pluton.

  • Sugilite in Manganese Silicate Rocks from the Hoskins Mine and Woods Mine, New South Wales, Australia
    Sugilite in manganese silicate rocks from the Hoskins mine and Woods mine, New South Wales, Australia Y. KAWACHI Geology Department, University of Otago, P.O.Box 56, Dunedin, New Zealand P. M. ASHLEY Department of Geology and Geophysics, University of New England, Armidale, NSW 2351, Australia D. VINCE 1A Ramsay Street, Essendon, Victoria 3040, Australia AND M. GOODWIN P.O.Bo• 314, Lightning Ridge, NSW 2834, Australia Abstract Sugilite relatively rich in manganese has been found at two new localities, the Hoskins and Woods mines in New South Wales, Australia. The occurrences are in manganese-rich silicate rocks of middle to upper greenschist facies (Hoskins mine) and hornblende hornfels facies (Woods mine). Coexisting minerals are members of the namansilite-aegirine and pectolite-serandite series, Mn-rich alkali amphiboles, alkali feldspar, braunite, rhodonite, tephroite, albite, microcline, norrishite, witherite, manganoan calcite, quartz, and several unidentified minerals. Woods mine sugilite is colour-zoned with pale mauve cores and colourless rims, whereas Hoskins mine sugilite is only weakly colour-zoned and pink to mauve. Within single samples, the chemical compositions of sugilite from both localities show wide ranges in A1 contents and less variable ranges of Fe and Mn, similar to trends in sugilite from other localities. The refractive indices and cell dimensions tend to show systematic increases progressing from Al-rich to Fe- Mn-rich. The formation of the sugilite is controlled by the high alkali (especially Li) and manganese contents of the country rock, reflected in the occurrences of coexisting high alkali- and manganese- bearing minerals, and by high fo2 conditions. KEYWORDS: sugilite, manganese silicate rocks, milarite group, New South Wales, Australia Introduction Na2K(Fe 3 +,Mn 3 +,Al)2Li3Sit2030.

Utahite is vitreous, brittle and nonfluorescent; hardness space-group choices P 1 or P 1, with refined unit-cell parameters (Mohs) 4-5; calculated density 5.33 gtcm' (for empirical formula), from powder data: a = 8.794(4), b = 9996(2), c = 5.660(2);\, a = 5.34 glcm' (for idealized formula). In polished section, utahite is 104.10(2)°, f3 = 90.07(5)°, y= 96.34(3YO, V = 479.4(3) ;\3, a:b:c = slightly bireflectant and nonpleochroic. 1n reflected plane-polar- 0.8798:1 :0.5662, Z = 1.
