A New Occurrence of Yimengite-Hawthorneite and Crichtonite-Group Minerals in An
26 A new occurrence of yimengite-hawthorneite and crichtonite-group minerals in an 27 orthopyroxenite from kimberlite: Implications for mantle metasomatism 1,* 1 1 28 Dmitriy I. Rezvukhin , Taisia A. Alifirova , Andrey V. Korsakov , Alexander V. 1 29 Golovin 1 30 Sobolev Institute of Geology and Mineralogy, Siberian Branch of the Russian Academy 31 of Sciences, 3 Koptyuga Avenue, Novosibirsk 630090, Russia 32 *corresponding author, e-mail: [email protected], [email protected] 33 34 ABSTRACT 35 LILE-enriched chromium titanates of the magnetoplumbite (AM12O19) and crichtonite 36 (ABC18T2O38) groups were recognized as abundant inclusions in orthopyroxene grains in a 37 mantle-derived xenolith from the Udachnaya-East kimberlite pipe, Daldyn field, Siberian craton. 38 The studied xenolith consists of three parts: an orthopyroxenite, a garnet clinopyroxenite, and a 39 garnet-orthopyroxene intermediate domain between the two. Within the host enstatite (Mg# 40 92.6) in the orthopyroxenitic part of the sample titanate inclusions are associated with Cr-spinel, 41 diopside, rutile, Mg-Cr-ilmenite, and pentlandite. Crichtonite-group minerals also occur as 42 lamellae inclusions in pyrope grains of the intermediate domain adjacent to the orthopyroxenite, 43 as well as in interstitial to enstatite oxide intergrowths together with Cr-spinel, rutile, and 44 ilmenite. 45 Yimengite-hawthorneite inclusions in enstatite contain (wt%) 3.72-8.04 BaO, 2.05-3.43 46 K2O, and 0.06-0.48 CaO. Their composition is transitional between yimengite and hawthorneite 47 endmembers with most grains exhibiting K-dominant chemistry. A distinct feature of the studied 48 yimengite-hawthorneite minerals is a high content of Al2O3 (5.74-7.69 wt%). -

Sul, 2291, CEP 50770-011, Recife, PE, Brazil Received 01 April 2014; accepted 05 July2014 Abstract: Alkali-bearing Ti oxides were identified in mantle xenoliths enclosed in kimberlite-like rocks from Limeira 1 alkaline intrusion from the Alto Paranaíba Igneous Province, southeastern Brazil. The metasomatic mineral assemblages include mathiasite-loveringite and priderite associated with clinopyroxene, phlogopite, ilmenite and rutile. Mathiasite-loveringite (55-60 wt.% TiO2; 5.2-6.7 wt.% ZrO2) occurs in peridotite xenoliths rimming chromite (∼50 wt.% Cr2O3) and subordinate ilmenite (12-13.4 wt.% MgO) in double reaction rim coronas. Priderite (Ba/(K+Ba)< 0:05) occurs in phlogopite-rich xenoliths as lamellae within Mg-ilmenite (8.4-9.8 wt.% MgO) or as intergrowths in rutile crystals that may be included in sagenitic phlogopite. Mathiasite-loveringite was formed by reaction of peridotite primary minerals with alkaline melts. The priderite was formed by reaction of peridotite minerals with ultrapotassic melts. -
IMA–CNMNC Approved Mineral Symbols
Mineralogical Magazine (2021), 85, 291–320 doi:10.1180/mgm.2021.43 Article IMA–CNMNC approved mineral symbols Laurence N. Warr* Institute of Geography and Geology, University of Greifswald, 17487 Greifswald, Germany Abstract Several text symbol lists for common rock-forming minerals have been published over the last 40 years, but no internationally agreed standard has yet been established. This contribution presents the first International Mineralogical Association (IMA) Commission on New Minerals, Nomenclature and Classification (CNMNC) approved collection of 5744 mineral name abbreviations by combining four methods of nomenclature based on the Kretz symbol approach. The collection incorporates 991 previously defined abbreviations for mineral groups and species and presents a further 4753 new symbols that cover all currently listed IMA minerals. Adopting IMA– CNMNC approved symbols is considered a necessary step in standardising abbreviations by employing a system compatible with that used for symbolising the chemical elements. Keywords: nomenclature, mineral names, symbols, abbreviations, groups, species, elements, IMA, CNMNC (Received 28 November 2020; accepted 14 May 2021; Accepted Manuscript published online: 18 May 2021; Associate Editor: Anthony R Kampf) Introduction used collection proposed by Whitney and Evans (2010).

Mantle Composition, Age and Geotherm Beneath the Darby Kimberlite Field, West Central Rae Craton by Garrett Alexander Harris
Mantle composition, age and geotherm beneath the Darby kimberlite field, west central Rae Craton by Garrett Alexander Harris A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science Department of Earth and Atmospheric Sciences University of Alberta © Garrett Alexander Harris, 2018 Abstract The Rae Craton, northern Canada, contains several diamondiferous kimberlite fields that have been a focus of episodic diamond exploration. Relatively little is known about the deep mantle lithosphere underpinning the architecturally complex crust. Previous studies in the region have focused on peridotite mantle xenoliths from Pelly Bay and Repulse Bay-east Rae and Somerset Island-Churchill Province (north Rae), no previous studies have investigated the lithospheric mantle beneath the west central Rae, specifically the Darby kimberlite field. This study presents bulk and mineral element and isotopic compositional data for peridotite and pyroxenite xenoliths from the Darby kimberlites representing fragments of the west central Rae lithosphere, as well as the first kimberlite eruption age of 542.2 2.6 Ma (2 σ; phlogopite Rb-Sr isochron) for the Darby kimberlite field. Darby peridotites have low bulk Al2O3 contents with highly-depleted olivine (median Mg# = 92.5), more depleted than peridotites from other locations on the Rae Craton such as Somerset Island and east central Rae kimberlites. These values are characteristic of cratonic lithosphere globally. Rhenium-Os TRD model ages are the oldest measured to date from peridotites of the Rae lithosphere, having a mode in the Meso/Neoarchean and ranging to Paleoproterozoic in age (~ 2.3 Ga). One harzburgite xenolith contains a G10D garnet. -
An Update on the Mineral-Like Sr-Containing Transition Metal Arsenates
Mineralogical Magazine (2021), 85, 416–430 doi:10.1180/mgm.2021.41 Article An update on the mineral-like Sr-containing transition metal arsenates Tamara Đorđević1* and Ljiljana Karanović2 1Institut für Mineralogie und Kristallographie, Universität Wien, Althanstr. 14, A-1090 Wien, Austria; and 2Laboratory of Crystallography, Faculty of Mining and Geology, Đušina 7, 11000 Belgrade, Serbia. Abstract We report on the crystal structures of three novel synthetic SrM-arsenates (M = Ni and Fe3+), isostructural or structurally related to the minerals from tsumcorite, carminite and brackebuschite groups. They were synthesised under mild hydrothermal conditions and further characterised using single-crystal X-ray diffraction (SXRD), scanning electron microscopy with energy dispersive spectroscopy (SEM- I · II 3+ EDS) and Raman spectroscopy. SXRD and SEM-EDS yielded formulae: ( ) SrNi2(AsO4)2 2H2O, ( )Sr1.4Fe1.6(AsO4)2(OH)1.6 and III 3+ ( ) SrFe (AsO4)(AsO3OH). All three structures are built up of slightly distorted MO6 octahedra and AsO4 tetrahedra that are linked by Sr2+ with different coordination geometries and hydrogen bonds. I represent a basic structure type typical for tsumcorite-group II 3+ minerals (space group C2/m) while has a new intermediate structure between carminite, PbFe2 (AsO4)2(OH)2 and arsenbracke- 3+ III I buschite, Pb2Fe (AsO4)2(OH) (s.g. Pm). is triclinic and adopts a new structure-type (s.g. P1). The structure of is built up of infinite linear edge-sharing NiO4(OH2)2 octahedral chains, extending along [010] and linked by AsO4 tetrahedra, SrO8 polyhedra and hydrogen II bonds. The structure of is characterised by the carminite-like FeO4(OH)2 octahedral chains and Edshammar-polyhedral chains, which II involves SrO11 coordination polyhedra similar to that of PbO11 in arsenbrackebuschite. -
