Oxyplumboroméit is a rare mineral belonging to the mineral class of oxides and hydroxides . It crystallizes in the cubic crystal system with the composition Pb ₂ Sb ₂ O ₆ O, so it is a lead - antimonate , the Y position of which is mainly occupied by oxygen ions .

Oxyplumboroméit occurs at its type locality in the form of subidiomorphic , octahedral crystals of <0.4 mm in size, which come together to form aggregates up to 2 mm in size and are closely associated with white calcite and pink-colored leucophoenicit .

The type locality of the Oxyplumboroméits is a Tephroit - Skarn in the iron-manganese mine "Harstigen" ("Harstigsgruvan") ( coordinates of the mine Harstigen ) near Pajsberg in the municipality of Filipstad , province of Värmland County or the historical province of Värmland in central Sweden .

Etymology and history

Gray-white to brownish, fibrous oxyplumboroméit crystal clusters on a slag matrix from the Letmathe slag dump , Iserlohn , North Rhine-Westphalia , Sauerland

In 1865, the Swedish mineralogist Lars Johan Igelström (1822–1897) discovered a mineral in the iron / manganese mines of Harstigen near Pajsberg, Sweden, which he derived from the Greek word μόυĭμος [ monimos ] for " due to its resistance to chemical influences " constant “ called monimolite . According to Brian Mason and Charles J. Vitaliano, this monimolite was a lead-antimonate with minor substitution of other elements for lead. Its powder diagram is practically identical to that of bindheimite , with the individual lines being better defined due to the perfect crystallinity. The type material for monimolite is kept in the collection of the Swedish National Museum of Natural History . Gustaf Flink and Adolf Erik Nordenskiöld investigated further monimolite stages from the type locality as well as other sites (Långban, Sweden).

In 2010, the IMA presented a new nomenclature for the minerals of the newly defined pyrochlore upper group (pyrochlore supergroup). Therein it was stipulated that the Pb-Sb-O-dominant member of this upper group is to be referred to as oxyplumboroméite. It was also stated that the “problematic” species monimolite is almost certainly identical to oxyplumboroméite, but this still had to be verified. Daniel Atencio and colleagues as well as Christy and Atencio also stated that a simple equation of monimolite (and bindheimite ) with oxyplumboroméite is not possible, since at this point in time a decision is made as to whether the monimolite type stage is actually oxyplumboroméite and whether which applies to all monimolite levels, was not possible.

Shortly afterwards, the physical, chemical and structural properties were of three derived from the collection of Igelström, now in the collection of Natural History Museum in Stockholm that are available Monimolit increments from Harstigen by a combination of microprobe analysis , x-ray diffraction (single crystal and powder diffraction), FTIR -Spectroscopy and Mössbauer spectroscopy examined. One of these stages, which corresponded best to the monimolite described by Igelström , turned out to be identical to oxyplumboroméit in the sense of the new nomenclature of the pyrochlore upper group. The new mineral was submitted to the International Mineralogical Association (IMA), which recognized it in 2013 under the tentative designation IMA 2013-042 . The first scientific description of this mineral was made in 2013 by a Swedish-Italian research team with Ulf Hålenius and Ferdinando Bosi in the English science magazine Mineralogical Magazine . The authors named the mineral in accordance with the nomenclature of the pyrochlore upper group due to its chemical composition with an A position dominated by lead , a B position dominated by Sb and a Y position dominated by O as oxyplumboroméite ( English Oxyplumboroméite ). Consequently, the name Monimolit should be discredited by the IMA.

The type material for Oxyplumboroméit is kept under the catalog number g22779 in the collection of the Natural History Museum in Stockholm , Sweden .

Roméit was a mineral named in 1841 by Augustin Alexis Damour in honor of Jean-Baptiste Romé de L'Isle , French mineralogist and one of the founders of crystallography, which was discredited when the nomenclature of the pyrochlore upper group was redefined in 2010 because it hide behind its composition the new minerals fluoronatroroméite, fluorcalcioroméite and oxycalcioroméite. He is also the namesake for the Roméit sub-group within the pyrochlore upper group.

classification

The current classification of the International Mineralogical Association (IMA) counts the oxyplumboroméite to the pyrochlore upper group with the general formula A _{2– m} B ₂ X _{6– w} Y _{1– n} , in which A , B , X and Y different positions in the structure the minerals of the pyrochlore upper group with A  = Na, Ca, Sr, Pb ²⁺ , Sn ²⁺ , Sb ³⁺ , Y, U, □, or H ₂ O; B = Ta ⁵⁺ , Nb ⁵⁺ , Ti ⁴⁺ , Sb ⁵⁺ , W ⁶⁺ , Al ^3+, or Mg ²⁺ ; X = O, OH or F and Y = OH ^- , F, O, □, H ₂ O or very large (>> 1.0 Å) monovalent cations such as K, Cs or Rb. To pyrochlore supergroup include not only Oxyplumboroméite still Fluorcalciomikrolith , Fluornatromikrolith , Hydrokenomikrolith , Hydroxycalciomikrolith , Hydroxykenomikrolith , Kenoplumbomikrolith , Oxynatromikrolith , Oxystannomikrolith , Oxystibiomikrolith , Cesiokenopyrochlor , Fluorcalciopyrochlor , Fluornatropyrochlor , Hydrokenopyrochlor , Hydropyrochlor , Hydroxycalciopyrochlor , Hydroxykenopyrochlor , Hydroxymanganopyrochlor , Hydroxynatropyrochlor , Oxycalciopyrochlor , Fluorcalcioroméit , Hydroxycalcioroméit , Hydroxyferroroméit , Oxycalcioroméit , Hydrokenoelsmoreit , Hydroxykenoelsmoreit , Fluornatrocoulsellit and Hydrokenoralstonit . Oxyplumboroméit forms together with fluorcalcioroméite, hydroxycalcioroméite, hydroxyferroroméite and oxycalcioroméit within the pyrochlore upper group the Roméit group .

The 8th edition of the mineral systematics according to Strunz , which is now outdated but still in use , does not yet list the oxyplumboroméite, but assigns the monimolite to the mineral class of "oxides and hydroxides" and there to the general section of "oxides with a metal: oxygen ratio = 2: 3 (M ₂ O ₃ and related compounds) ”, where together with Jixianit he created the unnamed group with the system no. IV / C.13 formed.

The 9th edition of Strunz's mineral systematics, which has been in effect since 2001 and is used by the International Mineralogical Association (IMA), assigns the oxyplumboroméit as well as the monimolite marked here as questionable ( Q ) to the department of “oxides with the molar ratio of metal: oxygen = 1: 2 and comparable “a. This is further subdivided according to the relative size of the cations involved and the crystal structure, so that the mineral is classified according to its composition and structure in the subsection “With large (± medium-sized) cations; Layers of edge-linked octahedra ”can be found, where together with all representatives of the pyrochlore, microlith, Betafit, Roméit and Elsmoreit groups, the pyrochlore supergroup with the system no. 4.DH.15 forms. Oxyplumboroméite is with Fluorcalcioroméit , Fluornatroroméit , Hydroxycalcioroméit (formerly lewisite ) Oxycalcioroméit , Bismutostibiconit (Q), Monimolit (Q), Partzit (Q), Stetefeldtit (Q), Stibiconit to find (Q) in the Roméitgruppe.

The systematics of minerals according to Dana , which is mainly used in the English-speaking area , does not yet know the oxyplumboroméite, but assigns the monimolite to the class of "phosphates, arsenates and vanadates" and there in the department of " antimonates ". Here it is together with stibiconite, bindheimite, roméite, lewisite, stetefeldite, bismutostibiconite and partzite in the stibiconite group with system no. 44.01.01 to be found in the subsection " Antimonates A (X ₂ O ₆ ) ".

Chemism

Eight microprobe analyzes on oxyplumboroméite grains from the type locality yielded mean values ​​of 48.69% Sb ₂ O ₃ ; 0.00% SiO ₂ ; 0.01% Al ₂ O ₃ ; 3.85% Fe ₂ O ₃ ; 8.46% CaO; 1.06% MnO; 0.23% SrO; 0.01% BaO; 35.82% PbO; 0.24% Na ₂ O; 0.07% SO3 and 0.05% H ₂ O (calculated); Total = 98.49%. Based on two cations on the B position per formula unit, the empirical formula ^A (Pb _0.92 Ca _0.87 Mn _0.09 Sr _0.01 Na _0.05 ) _{Σ = 1.93} ^B (Sb _{1 , 73} Fe ³⁺ _0.27 ) _{Σ = 2.00} ^{X + Y} [O _6.64 (OH) _0.03 ] _{Σ = 6.67} calculated, the formula for the end link Pb ₂ Sb ₂ O ₇ (or . Pb ₂ Sb ₂ O ₆ O) has been simplified.

Besides oxyplumboroméite and the phases in question bindheimite , Pb ₂ Sb ₂ O ₆ O and taznite , Pb ₂ Sb ₂ O ₆ O, the only mineral with the element combination Pb - Sb - O is rosiaite , PbSb ⁵⁺ ₂ O ₆ .

Within the pyrochlore upper group there are theoretically a multitude of substitution possibilities due to the four different positions to be occupied. Oxyplumboroméite is the Pb-dominant analogue of the Ca-dominated oxycalcioroméite and to the Cu-dominated, but questionable cuproroméite, Cu ₂ Sb ₂ (O, OH) ₇ .

Bindheimite is not identical to monimolite, but rather identical to the hydroxyplumboroméite, which has not yet been described as a mineral , due to the much higher H ₂ O content . Consequently, the general assumption that bindheimite and oxyplumboroméite are identical is not justified.

Crystal structure

Crystal structure of oxyplumboroméite as a cation-centered polyhedral representation

Oxyplumboroméite crystallizes in the cubic crystal system in the space group Fd 3 m (space group no. 227) with the lattice parameter a = 10.3783  Å and eight formula units per unit cell .

The crystal structure of the Oxyplumboroméits (compare with the adjacent structural drawing) can be used as three-dimensional, typical for representatives of the pyrochlore supergroup framework of corner-sharing B O ₆ - octahedra are described, wherein in the interstices of this scaffold, the A cations and the oxygen ions are sitting. The eight-coordinate A position is mainly occupied by Pb and , to a lesser extent, also by Ca. In addition to Sb ⁵⁺ , Fe ³⁺ also sits on the octahedrally coordinated B position .

Oxyplumboroméit is isotypic (isostructural) to all other representatives of the pyrochlore upper group which crystallize in space group Fd 3 m (space group no. 227) .

properties

morphology

Oxyplumboroméit forms rounded aggregates of subidiomorphic octahedral crystals {111} at its type locality, on which the octahedral surfaces are only partially developed. The <0.4 mm crystals come together to form aggregates of a maximum of 2 mm.

• Costume and habitus of oxyplumboroméit or "monimolite" crystals
• 

  1. Octahedral crystal with the octahedron {111} as the only surface shape

• 

  2. Combination of octahedron {111} and icositetrahedron {311} according to Flink

• 

  3. Combination of {100}, {111} and {110} according to Flink

Gustaf Flink, on the other hand, described the monimolite in the form of two different types (compare the crystal drawings opposite). Type I forms small, only millimeter-sized crystals with the octahedron as the dominant shape, on which the corners are modified by the icositetrahedron {311} as a tapering of the corners. The crystals are idiomorphic and sharp-edged and show a strong luster, especially on the octahedral surfaces. The surfaces of {311} are usually less shiny and have numerous irregular depressions on the surface. The shape of type II crystals that determines the costume is the hexahedron {100}, which can be joined by octahedra {111} and rhombic dodecahedron {110}. The octahedron is sometimes in equilibrium with the cube, while the rhombic dodecahedron usually appears to be very subordinate. The faces of the cube are often quite strongly curved. Some of the crystals are elongated along one of the three crystallographic axes - and in the zone determined by this, the surfaces of {100} and {110} are equally developed, so that eight-sided prisms appear. Type II crystals are similar in size to those of type I and have flat and shiny surfaces. Also in coarse masses and as a coating. Finally, also in pseudomorphoses for primary Pb-Sb-containing minerals such as. B. Bournonite , PbCu [SbS ₃ ].

physical and chemical properties

The crystals of the oxyplumboroméite are yellow to brownish-yellow, while monimolite is yellowish, brownish-green or dark-brown to almost black and the crystal surfaces often have beautiful variegated tarnish colors. The line color is indicated as straw yellow, lemon yellow or cinnamon brown. The surfaces of the translucent to almost opaque monimolite have a greasy to metallic sheen , whereby monimolite crystals of type II are only translucent in the thinnest splinters with a brown color. The high gloss agrees very well with the very high value for light refraction (n = 2.061). Oxyplumboroméit is optically isotropic. Type I monimolite is brown-yellow in the reflected light, sometimes with a tinge of green. In the thin section the mineral is yellow-green, translucent and parallel (111) completely optically isotropic. Monimolite crystals of type II are only slightly transparent even in the thin section and show an outer, slightly more translucent zone and an inner, less translucent core. The former often shows traces of birefringence, the latter is optically completely isotropic.

Monimolite has an indistinct cleavage according to the {111} octahedron. Due to its brittleness , however , it breaks like amblygonite , with the fracture surfaces being uneven. A half- shell to splintery break is specified for monimolite . With a Mohs hardness of ≈ 5 or 5 to 6, the mineral is one of the medium-hard minerals and, like the reference minerals apatite (hardness 5), can be scratched with a pocket knife or like orthoclase (hardness 6) with a steel file. The calculated density for oxyplumboroméite is 6.732 g / cm³. Information on fluorescence in long-wave or short-wave UV light is missing for the mineral.

Monimolite melts in the pliers in front of the soldering tube to a black, blistered slag, gives a lead and antimony coating on coal in front of the soldering tube, as well as a light, shiny, supple metal grain made of lead and antimony. Nothing volatile escapes when heated in the flask. Borax and phosphorus salt also dissolve the mineral in fairly considerable quantities to a yellow glass that does not change in the reducing flame; with soda manganese reaction. With the exception of the variant "Type II", which dissolves easily in melting alkali metal carbonate, none of the monimolites investigated are soluble in either the strongest acids or in dissolved or melting caustic and carbonic acid alkalis . After reduction in a stream of hydrogen , the mineral is acid-soluble.

Education and Locations

Yellow, fibrous oxyplumboroméite on quartz from the pegmatite Viitaniemi near Eräjärvi / Orivesi , Pirkanmaa (size: 50 mm × 25 mm × 25 mm)

The type locality for Oxyplumboroméit is a Tephroit - Skarn in the iron-manganese mine "Harstigen" ("Harstigsgruvan") near Pajsberg in the municipality of Filipstad , province of Värmland County or the historical province of Värmland in central Sweden . The small Fe-Mn deposit with a mineralization similar to Långban is 33 m deep, 15 m long and 2 m wide and sits in a dolomite lens between potassium-containing metarhyolites and basic rocks. It was dismantled between 1847 and 1853 and from 1887 to 1889; the total production was 356 tons of iron ore and 153 tons of manganese ore.

Oxyplumboroméite found on its type locality in up to 2 cm mighty crevasses in a Tephroit - skarn . The accompanying minerals of the oxyplumboroméite include calcite and leucophoenicite . Monimolite type I from Harstigen was found on cracks and in cracks coarse or, if there was a larger amount of space, also in crystals, accompanied by small platy magnetite octahedra, which are surrounded by a felt work of hair-fine, needle-like Richterite crystals. Other companions are gray Tephroit and light Hedyphan . Monimolite type II from Harstigen occurs only in fairly wide crevices, subsequently filled with calcite, and is accompanied by coarse tephroit and yellow-brown needle-like Richterite, which sits in dense masses between the monimolite crystals. In the vicinity of the mineral there are also yellow garnet in small irregular grains as well as coarse hedyphan and scales of graphite or molybdenite . Monimolite from Långban appeared, accompanied by rhodonite and tephroit, waxed in calcite.
