E-mail: [email protected] (Received 27 March 2020; revision accepted 09 September 2020) Abstract–Calcium-aluminum-rich inclusions (CAIs) are the first solid materials formed in the solar nebula. Among them, ultrarefractory inclusions are very rare. In this study, we report on the mineralogical features and oxygen isotopic compositions of minerals in a new ultrarefractory inclusion CAI 007 from the CV3 chondrite Northwest Africa (NWA) 3118. The CAI 007 inclusion is porous and has a layered (core–mantle–rim) texture. The core is dominant in area and mainly consists of Y-rich perovskite and Zr-rich davisite, with minor refractory metal nuggets, Zr,Sc-rich oxide minerals (calzirtite and tazheranite), and Fe-rich spinel. The calzirtite and tazheranite are closely intergrown, probably derived from a precursor phase due to thermal metamorphism on the parent body.

  • Allendeite (Sc4zr3o12) and Hexamolybdenum (Mo,Ru,Fe), Two New Minerals from an Ultrarefractory Inclusion from the Allende Meteorite
    American Mineralogist, Volume 99, pages 654–666, 2014 Allendeite (Sc4Zr3O12) and hexamolybdenum (Mo,Ru,Fe), two new minerals from an ultrarefractory inclusion from the Allende meteorite Chi Ma*, John R. BeCkett and GeoRGe R. RossMan Division of Geological and Planetary Sciences, California Institute of Technology, Pasadena, California 91125, U.S.A. aBstRaCt During a nanomineralogy investigation of the Allende meteorite with analytical scanning elec- tron microscopy, two new minerals were discovered; both occur as micro- to nano-crystals in an ultrarefractory inclusion, ACM-1. They are allendeite, Sc4Zr3O12, a new Sc- and Zr-rich oxide; and hexamolybdenum (Mo,Ru,Fe,Ir,Os), a Mo-dominant alloy. Allendeite is trigonal, R3, a = 9.396, c = 8.720, V = 666.7 Å3, and Z = 3, with a calculated density of 4.84 g/cm3 via the previously described structure and our observed chemistry. Hexamolybdenum is hexagonal, P63/mmc, a = 2.7506, c = 4.4318 Å, V = 29.04 Å3, and Z = 2, with a calculated density of 11.90 g/cm3 via the known structure and our observed chemistry. Allendeite is named after the Allende meteorite. The name hexamolyb- denum refers to the symmetry (primitive hexagonal) and composition (Mo-rich). The two minerals an important ultrarefractory carrier phase linking Zr-,Sc-oxides to the more common Sc-,Zr-enriched pyroxenes in Ca-Al-rich inclusions. Hexamolybdenum is part of a continuum of high-temperature al- loys in meteorites supplying a link between Os- and/or Ru-rich and Fe-rich meteoritic alloys. It may be a derivative of the former and a precursor of the latter.

  • Allendeite and Hexamolybdenum: Two New Ultra-Refractory Minerals in Allende and Two Missing Links C
    40th Lunar and Planetary Science Conference (2009) 1402.pdf Allendeite and Hexamolybdenum: Two New Ultra-Refractory Minerals in Allende and Two Missing Links C. Ma*, J.R. Beckett, and G.R. Rossman; Division of Geological and Planetary Sciences, California Institute of Technology, Pasadena CA 91125, *[email protected]. Introduction: During our nano-mineralogy inves- tigation of the Allende meteorite, we discovered two new minerals that occur as micro- to nano-crystals in refractory inclusions: Allendeite, Sc4Zr3O12, a new Sc- and Zr-rich oxide; and hexamolybdenum, (Mo,Ru,Fe), a Mo-dominant alloy. Allendeite, which may be an important ultra-refractory carrier linking Zr-, Sc- ox- ides and the more common Sc-, Zr-enriched clinopy- roxenes (Cpx) in CAIs, hosts perovskite (Pv), spinel (Sp), Os-Ir-W-Mo alloys, and hexamolybdenum. The observation of two structurally and chemically distinct highly refractory, low-Pt alloy minerals not associated with Fe-Ni alloys provides the first direct physical evidence for at least two separate carriers of the highly Fig. 1. Backscattered electron (BSE) image of the refractory metals in CAIs. Hexamolybdenum links Os- refractory inclusion containing allendeite and hex- rich and Pt-rich meteoritic alloys and may be a precur- amolybdenum. sor of the latter. Both new minerals have been ap- proved by the Commission on New Minerals, Nomen- clature and Classification of the International Minera- logical Association (IMA 2007-027, 029). Occurrence, Chemistry and Crystallography: Allendeite and hexamolybdenum occur in a partially altered refractory inclusion ~70 μm x 120 μm in sec- tion USNM 7554 (Fig. 1). Fig. 2 shows a single 15x25 μm crystal (revealed by electron backscatter diffraction (EBSD) orientation mapping) of allendeite with in- cluded Pv, Os-Ir-Mo-W alloy, and Sc-stabilized taz- heranite (Taz; cubic zirconia).

Natural catalysts such as metalloenzymes have maintained energy cycles on Earth, thus proving themselves the optimal catalysts. In the previous research results, the structural and functional analogs of enzymes and nano-sized electrocatalysts have shown promising activities in energy conversion reactions. Mo ion plays essential roles in natural and artificial catalysts, and the unique electrochemical properties render its versatile utilization as an electrocatalyst. In this review paper, we show the current understandings of the Mo-enzyme active sites and the recent advances in the synthesis of Mo-catalysts aiming for high-performing catalysts.

However, to emphasize specific objects in the solar system, which contain minerals, composition and type of origin “hexa-” may be such as spinel, melilite, hibonite, and perovskite, important. Pure Molybdenum and Iridium (also Fe and presumably condensed from a cooling gas of the solar Ni) have cubic crystal structure, however, with an nebula [1]. They often contain fremdlinge and refractory metal nuggets (RMN), that are enriched by siderophile elements such as PGE, Mo, and W [2-3]. Three major groups of hypotheses have been proposed to explain the origin of RMN: (1) condensation from the solar nebula or stellar environments, which is supported by data from type A CAI and studies of presolar grains [4-7]; (2) precipitation from CAI melt, which is very likely for type B CAI [8-9], or (3) secondary processes in the parent bodies or nebulae, which may be applicable for PMNs in fremdlinge and RMN of complex composition Fig. 1.

Kartashov, Enver E. Asadulin, Oleg A. Bogatikov Institute of Geology of Ore Deposits, Petrography, Mineralogy and Geochemistry (IGEM), Russian Academy of Sciences, Moscow, [email protected] This paper discusses the results of study of the impact glass fragments from the Mare Fecunditatis and Mare Crisium regolith samples brought on the Earth by the Soviet Automatic stations Luna-16 and Luna-24. Nanoinclusions of native molybdenum, iron and titanium were found in the samples with scanning and trans- mission electron microscopy (SEM, TEM). It is shown that these inclusions are single crystals. A natural high pressure native w titanium was identified for the first time. The composition and structure of glass matrix of the regolith samples indicates its extreme micro and nano heterogeneity. The probable formation mechanisms of the studied nanocrystals are discussed. 3 tables, 10 figures, 26 references.
