...), Slovakia. It occurs as anhedral grains or as tetrahedral crystals, black in colour, with metallic lustre. At BdV it is associated with cinnabar and chalcostibite in dolomite veins. At Jh, tetrahedrite-(Hg) is associated with baryte and chalcopyrite in quartz–siderite–dolomite veins; at R it is associated...

...Mohammad Wahsha; Laura Maleci; Claudio Bini Abstract Exploitation of ore minerals (cinnabar, chalcopyrite, sphalerite) from the old mine in Vallalta (Belluno, NE Italy) has resulted in serious environmental impacts, including the acidification of water, and the contamination of soils and plants...

... with cinnabar, dugganite, eurekadumpite, and gold in vugs in a matrix composed of quartz and dolomite. The mineral occurs as tiny light greenish-gray platelets, generally intermixed with amorphous material, forming porous masses that are apparently replacements of earlier phases. The streak is white, the luster...

... and techniques in the Roman province of Syria Palestina follow Empire tendencies, although advantage was taken also of the local availability of raw materials. Seven different pigments were identified, including Egyptian blue and cinnabar, and the predominant wall painting technique used was fresco occasionally...

Molina Donoso Abstract The new mineral torrecillasite (IMA2013-112), Na ( As , Sb ) 4 3 + , was found at the Torrecillas mine, Iquique Province, Chile, where it occurs as a secondary alteration phase in association with anhydrite, cinnabar, gypsum, halite...

...Paolo Ballirano; Michela Botticelli; Adriana Maras Abstract Cinnabar use on painting is historically documented from ancient times, together with its tendency to darken. The most accepted mechanism for this kind of deterioration considers cinnabar (α-HgS) transformation into its polymorph...

... in the baryte + pyrite + iron oxides ore. Associated minerals are calcite, cinnabar, derbylite, dolomite, hematite, ‘mica’, pyrite, sphalerite and ‘tourmaline’. Oxycalcioroméite is reddish-brown in colour and transparent. It is isotropic, with n calc = 1.950. Electron microprobe analysis gave (wt.%; n = 6) Sb 2...

... principles of mineral evolution. Metacinnabar (HgS) and native Hg are the only two species reported from meteorites, specifically, the primitive H3 Tieschitz chondrite with an age of 4550 Ma. Since the first terrestrial appearance of cinnabar more than 3 billion years ago, mercury minerals have been present...

...) in the temperature range 467–522 K. This phase disappears at 527 K, and the metacinnabar phase changes to a well crystalline cubic phase; cinnabar develops at 542 K. The proportion of cinnabar continues to increase up to 647 K. Both metacinnabar and cinnabar phases are retained on cooling. No phase transitions were...

...Gwendy E. M. Hall; Pierre Pelchat; Jeanne B. Percival Abstract The final step in a sequential extraction procedure for Hg in geological samples usually involves a strong acid attack such as aqua regia. It is assumed that the Hg component measured in this step represents HgS (cinnabar), the common...

... acted as an extractant itself and therefore could not be used to minimize resorption of Hg onto the sample during leaching. The minerals Hg 2 Cl 2 , HgCl 2 , HgO (red and yellow), HgS (synthetic and cinnabar) and Hg (0) were used alone and mixed with GG to evaluate the selectivity of the scheme...

Finely disseminated cinnabar, acicular stibnite, pyrite framboids and minor livingstonite are distributed through both massive sinter and stromatolitic fabrics with sulphide mineralization extending from fractured rocks about former spring vents into less disturbed sinter...

... understood, and the reactivity and properties of intermediate phases have not been established. There are two common polymorphs of HgS: metacinnabar, which is stable at high temperatures and has a cubic ZnS structure, and cinnabar, the stable low-temperature phase, which is trigonal and contains linear S...

... in the form of cinnabar (HgS), though metacinnabar and native Hg are also occasionally found ( Luque 1985 ). Cinnabar is irregularly distributed both in veinlets inside the conglomeratic bodies and scattered inside the matrix of the conglomerate; it also appears in contact zones between Carboniferous...

The mineral is found as an isolated cluster of crystals in a shallow depression, associated with cinnabar and edoylerite, on a single specimen of brecciated silica–carbonate rock. Individual crystals do not exceed 0.17 mm in longest dimension and are subhedral...
