... O (5 ≤ n ≤ 14), has been discovered in the Buca della Vena baryte ± iron oxides ± pyrite ore deposit, Apuan Alps, Tuscany (Italy), and in the Horní Město deposit, northern Moravia (Czech Republic). It occurs as pinkish to lilac tabular {001} crystals, with a pseudohexagonal outline, up to 0.25 mm...

...Paolo Orlandi; Alain Meerschaut; Yves Moëlo; Pierre Palvadeau; Philippe Léone Abstract Rouxelite, Cu 2 HgPb 22 Sb 28 S 64 (O,S) 2 , is a new species of sulfosalt discovered in the Buca della Vena Fe–Ba deposit, Apuan Alps, Italy. It occurs as acicular metallic crystals in calcite veins...

... 3 Pb 16 Sb 18 S 46 , is a new sulfosalt discovered in the Fe-Ba deposit of Buca della Vena, Apuan Alps (Italy). It occurs as black acicular metallic crystals in calcite veins; reflectance values in air are (R %, λ nm): 33.1 ( 470 ), 30.0 ( 546 ), 28.8 ( 589 ), 26.5 ( 650 ). Marrucciite is monoclinic...

...Paolo ORLANDI; Yves MOËLO; Alain MEERSCHAUT; Pierre PALVADEAU; Philippe LEONE Abstract Pellouxite, the second natural oxy-chloro-sulfosalt after pillaite, has been discovered in cavities of calcite veins in the small Fe-Ba deposit of Buca della Vena mine, Apuan Alps (Tuscany, Italy). The new...

... provided the systematic mineralogy with an exceptional series of rare or new minerals. Buca della Vena, Fornovolasco, Monte Arsiccio and Pollone mines are indeed the type localities for sixteen mineral species, thus testifying to the huge scientific importance of this kind of ore deposits, whose mineralogy...

...) is given, along with a brief history of previous studies on this mineral species. Tetrahedrite-(Hg) was found in the pyrite ± baryte ± iron-oxide ore deposit of Buca della Vena mine (43°59’55’’N, 10°18’37’’E), Stazzema, Apuan Alps, Lucca Province, Tuscany, Italy. The ore bodies are located...

... been detected: major Pb, Sb and S and minor Cu, Ag, Hg, Tl and As; Bi occurs in only four spot analyses. Among the minor elements, four (Ag, Tl, As and Bi) were not detected previously in rouxelite from the type deposit of Buca della Vena, whereas Ag also occurred in the specimen from Magurka ( Orlandi...

... with the Monte Arsiccio and Buca della Vena mines, the Pollone deposit occurs in a barite district that has been extensively studied ( Lattanzi et al . 1994 , and references therein). According to Costagliola et al . (1998) , vein formation at Pollone was controlled by the development of shear zones during...

... are missing. The new finding from the Buca della Vena mine allowed us to propose the approval of oxycalcioroméite as a valid mineral species. The mineral and its name were approved by the IMA-CNMNC, under the number 2012-022. The holotype specimen of oxycalcioroméite is deposited in the mineralogical...

..., but also to the oxygen fugacity, as for scainiite. The Buca della Vena Fe-Ba deposit shows a complex mineralogy, with many rare minerals ( Orlandi & Checchi, 1986 ). Recently two new Pb-Sb sulfosalts were discovered; the first one, scainiite, Pb 14 Sb 30 S 54 O 5 , has been described by Orlandi et...

...-quantitative results of chemical analyses. There are no other published accounts of schafarzikite from Pernek and no reports of finding this mineral in Pernek since the 1920’s. Schafarzikite was also described from Buca della Vena in the Apuan Alps in Italy ( Mellini et al. , 1979 ), from Lac Nicolet mine...

... = Type locality. The first Pb-Sb oxy-sulfosalt to be described was scainiite ( Orlandi et al. , 1999 ) from the Buca della Vena mine, Apuan Alps, Tuscany, Italy, a small mine exploiting a baryte, pyrite and iron oxides (magnetite, hematite) deposit. Some years later, other new oxy-sulfosalts were...

... identified in the second kind of occurrence. These deposits are hosted in a lithologically more complex situation; in fact, sulfosalts have been observed in fractures and veins embedded in lenses of dolostones (Buca della Vena, Monte Arsiccio, and Fornovolasco mines) as well as in the baryte ore (Pollone...

... with the crystal structure of another new mineral compound, pellouxite, a Pb-Sb-(Cu,Ag) oxychloro-sulfide ( Orlandi et al. , 2004 ). All these three mineral species were found at Buca della Vena mine, a small Fe-Ba deposit from Apuan Alps, Tuscany ( Orlandi & Checchi, 1986 ; Orlandi et al. , 1999 , 2001...

... Å structure of chovanite from a new occurrence from the Pollone mine have been given. The crystallization of meerschautite, as well as that of chovanite, implies very specific geochemical conditions, with f O 2 / f S 2 relatively stable. Whereas at Buca della Vena, where several oxysulfosalts...
