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. -

.. & METEORITIC RUTILE Peter R. Buseck Departments of Geology and Chemistry Arizona State University Tempe, Arizona Klaus Keil Space Sciences Division National Aeronautics and Space Administration Ames Research Center Mof fett Field, California r ABSTRACT Rutile has not been widely recognized as a meteoritic constituent. show, Recent microscopic and electron microprobe studies however, that Ti02 . is a reasonably widespread phase, albeit in minor amounts. X-ray diffraction studies confirm the Ti02 to be rutile. It was observed in the following meteorites - Allegan, Bondoc, Estherville, Farmington, and Vaca Muerta, The rutile is associated primarily with ilmenite and chromite, in some cases as exsolution lamellae. Accepted for publication by American Mineralogist . Rutile, as a meteoritic phase, is not widely known. In their sunanary . of meteorite mineralogy neither Mason (1962) nor Ramdohr (1963) report rutile as a mineral occurring in meteorites, although Ramdohr did describe a similar phase from the Faxmington meteorite in his list of "unidentified minerals," He suggested (correctly) that his "mineral D" dght be rutile. He also ob- served it in several mesosiderites. The mineral was recently mentioned to occur in Vaca Huerta (Fleischer, et al., 1965) and in Odessa (El Goresy, 1965). We have found rutile in the meteorites Allegan, Bondoc, Estherville, Farming- ton, and Vaca Muerta; although nowhere an abundant phase, it appears to be rather widespread. Of the several meteorites in which it was observed, rutile is the most abundant in the Farmington L-group chondrite. There it occurs in fine lamellae in ilmenite. The ilmenite is only sparsely distributed within the . meteorite although wherever it does occur it is in moderately large clusters - up to 0.5 mn in diameter - and it then is usually associated with chromite as well as rutile (Buseck, et al., 1965), Optically, the rutile has a faintly bluish tinge when viewed in reflected, plane-polarized light with immersion objectives. -
Chemical and Structural Evolution of “Metamorphic Vermiculite” in Metaclastic Rocks of the Betic Cordillera, Málaga, Spain: a Synthesis
249 The Canadian Mineralogist Vol. 44, pp. 249-265 (2006) CHEMICAL AND STRUCTURAL EVOLUTION OF “METAMORPHIC VERMICULITE” IN METACLASTIC ROCKS OF THE BETIC CORDILLERA, MÁLAGA, SPAIN: A SYNTHESIS MARÍA DOLORES RUIZ CRUZ§ Departamento de Química Inorgánica, Cristalografía y Mineralogía, Universidad de Málaga, Campus de Teatinos, E-29071 Málaga, Spain JOSÉ MIGUEL NIETO Departamento de Geología, Facultad de Ciencias Experimentales, Universidad de Huelva, E-21071 Huelva, Spain ABSTRACT Vermiculite-like minerals from a metamorphic sequence of the Betic Cordillera, near Málaga, southeastern Spain, were investigated in detail by X-ray diffraction, electron-microprobe analysis, and transmission-analytical electron microscopy. Our results reveal that the chlorite-to-biotite transformation is much more complex than previously assumed. In addition to mixed- layer minerals with a mica:chlorite ratio of 2:1 and 1:1, which had previously been identifi ed, mixed-layer phases with very high and very low chlorite:vermiculite ratios have been identifi ed, together with true vermiculite, as intermediate steps in the chlorite-to-biotite transformation. The observed sequence is: chlorite → random to ordered 1:2 mica–chlorite mixed-layer phases → regular 1:1 chlorite–vermiculite mixed-layer phases → Vrm-rich chlorite–vermiculite mixed-layer phases → vermiculite → biotite. This sequence includes a continuous increase of interlayer cation content, and is similar to that described in the smectite- to-illite transformation. The high Na content of most of these phases suggests that in the absence of K-feldspar, two parallel sites of reactants, chlorite + phengite and chlorite + albite, account for the formation of vermiculitic phases, and later, of biotite. Keywords: mixed-layer minerals, metamorphic vermiculite, X-ray diffraction, electron-microprobe analysis, transmission elec- tron microscopy, analytical electron microscopy, Betic Cordillera, Spain. -

Received: 4 January 2020; Accepted: 19 February 2020; Published: 23 February 2020 Abstract: Metallic and metal oxide nanoparticles (NPs), including titanium dioxide NPs, among polymeric NPs, liposomes, micelles, quantum dots, dendrimers, or fullerenes, are becoming more and more important due to their potential use in novel medical therapies. Titanium dioxide (titanium(IV) oxide, titania, TiO2) is an inorganic compound that owes its recent rise in scientific interest to photoactivity. After the illumination in aqueous media with UV light, TiO2 produces an array of reactive oxygen species (ROS). The capability to produce ROS and thus induce cell death has found application in the photodynamic therapy (PDT) for the treatment of a wide range of maladies, from psoriasis to cancer. -

Centre d'Orsay, Bat. 504, F-91504, Paris, France Accepted 29 August 2000 Abstract The anorogenic, alkaline silica-oversaturated Serra do Meio suite is located within the Riacho do Pontal fold belt, northeast Brazil. This suite, assumed to be Paleoproterozoic in age, encompasses metaluminous and peralkaline granites which have been deformed during the Neoproterozoic collisional event. Preserved late-magmatic to subsolidus amphiboles belong to the riebeckite±arfvedsonite and riebeckite± winchite solid solutions. Riebeckite±winchite is frequently rimmed by Ti±aegirine. Ti-aegirine cores are strongly enriched in Nb, Y, Hf, and REE, which signi®cantly decrease in concentrations towards the rims. REE patterns of Ti-aegirine are strikingly similar to Ti-pyroxenes from the IlõÂmaussaq peralkaline intrusion. Recrystallisation of mineral assemblages was associated with deformation although some original grains are still preserved. Magmatic annite was converted into magnetite and biotite with lower Fe/(Fe 1 Mg) ratios. Recrystallised amphibole is pure riebeckite. Magmatic Ti±Na-bearing pyroxene was converted to low-Ti aegirine 1 titanite ^ astrophyllite/aenigmatite. -

Agpaitic nepheline syenites have complex, Na-Ca-Zr-Ti minerals as the main hosts for zirconium and titanium, rather than zircon and titanite, which are characteristic for miaskitic rocks. The transition from a miaskitic to an agpaitic crystallization regime in silica-undersaturated magma has traditionally been related to increasing peralkalinity of the magma, but halogen and water contents are also important parameters. The Larvik Plutonic Complex (LPC) in the Permian Oslo Rift, Norway consists of intrusions of hypersolvus monzonite (larvikite), nepheline monzonite (lardalite) and nepheline syenite. Pegmatites ranging in composition from miaskitic syenite with or without nepheline to mildly agpaitic nepheline syenite are the latest products of magmatic differentiation in the complex. The pegmatites can be grouped in (at least) four distinct suites from their magmatic Ti and Zr silicate mineral assemblages. -

ABSTRACT Minerals containing cobalt as an essential element display systematic trends in their diversity and distribution. We employ data for 66 approved Co mineral species (as tabulated by the official mineral list of the International Mineralogical Association, http://rruff.info/ima, as of 1 March 2016), represent- ing 3554 mineral species-locality pairs (www.mindat.org and other sources, as of 1 March 2016). We find that cobalt-containing mineral species, for which 20% are known at only one locality and more than half are known from five or fewer localities, conform to a Large Number of Rare Events (LNRE) distribution. Our model predicts that at least 81 Co minerals exist in Earth’s crust today, indicating that at least 15 species have yet to be discovered—a minimum estimate because it assumes that new minerals will be found only using the same methods as in the past. Numerous additional cobalt miner- als likely await discovery using micro-analytical methods.
