“…For example, perroudite (5HgS•Ag 4 I 2 Cl 2 ) and capgaronnite occur by alteration of Hg-and Ag-bearing tennantite (Cu 12 As 4 S 13 ) or tetrahedrite (Cu 12 Sb 4 S 13 ) by halide-bearing solutions of marine origin (Sarp et al 1987). Similarly, corderoite and kenhsuite (the α and γ forms of Hg 3 S 2 Cl 2 , respectively), radkeite (Hg 3 S 2 ClI), eglestonite {[Hg 1+ ] 6 O(OH)Cl 3 }, and many other Hg minerals occur as hydrothermal alteration products of cinnabar (Tunell et al 1977;Vasil'eva and Lavrent'ev 1980;Roberts et al 1981Roberts et al , 1990Roberts et al , 1993Roberts et al , 2003aRoberts et al , 2005McCormack et al 1991;McCormack and Dickson 1998;Pervukhina et al 2008). For example, perroudite and danielsite [(Cu,Ag) 14 HgS 8 ] occur in a supergene assemblage in gossan at Coppin Pool, Western Australia, hosted by sedimentary host rocks of the Fortescue Group (Nickel 1985(Nickel , 1987Sarp et al 1987), which has been dated 2.765-2.697 Ga elsewhere in the Hamersley Basin (Arndt et al 1991).…”

Analyses of the temporal and geographic distribution of earliest recorded appearances of the 88 IMA-approved mercury minerals plus two potentially valid species exemplify 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 continuously at or near Earth's surface.Mercury mineral evolution is characterized by episodic deposition and diversification, perhaps associated with the supercontinent cycle. We observe statistically significant increases in the number of reported Hg mineral localities and new Hg species at ~2.8-2.6, ~1.9-1.8, and ~0.43-0.25 Gaintervals that correlate with episodes of presumed supercontinent assembly and associated orogenies of Kenorland (Superia), Columbia (Nuna), and Pangea, respectively. In constrast, few Hg deposits or new species of mercury minerals are reported from the intervals of supercontinent stability and breakup at ~2.5-1.9, ~1.8-1.2, and 1.1-0.8 Ga. The interval of Pangean supercontinent stability and breakup (~250-65 Ma) is also marked by a significant decline in reported mercury mineralization; however, rocks of the last 65 million years, during which Pangea has continued to diverge, is characterized by numerous ephemeral near-surface Hg deposits.The period ~1.2-1.0 Ga, during the assembly of the Rodinian supercontinent, is an exception because of the absence of new Hg minerals or deposits from this period. Episodes of Hg mineralization reflect metamorphism of Hg-enriched marine black shales at zones of continental convergence. We suggest that Hg was effectively sequestered as insoluble nanoparticles of cinnabar (HgS) or tiemannite (HgSe) during the period of the sulfidic "intermediate ocean" (~1.85-0.85 Ga); consequently, few Hg deposits formed during the aggregation of Rodinia, whereas several deposits date from 800-600 Ma, a period that overlaps with the rifting and breakup of Rodinia.Nearly all Hg mineral species (87 of 90 known), as well as all major economic Hg deposits, are known to occur in formations ≤400 million years old. This relatively recent diversification arises, in part, from the ephemeral nature of many Hg minerals. In addition, mercury mineralization is strongly enhanced by interactions with organic matter, so the relatively recent pulse of new Hg minerals may reflect the rise of a terrestrial biosphere at ~400 Ma.

“…Figure 22 a presents, as an example, the arrangement of centres of [Hg 2 ] dumbbell pairs and the centres of [SbO 6 ] octahedra in the coordinate plane of the lattice for kelyanite [Hg 2 ] 6 SbO 6 BrCl 2 (Ref. 130) and a network of lattice points. The effect of ordering of these groups of atoms can be seen in their arrangement in one of the (003) planes of the structure, which is the (111) plane for the subcell (Fig.…”

“…5. When the crystal properties are analyzed in terms of the atom space distribution and atom-atom first-shell contacts, it is reasonable to conclude that the crystal state is controlled by specific ordering rules [30,[40][41][42]. The distribution of heavy atoms, cations in niobates and tantalates, is most strictly limited by atomic ordering.…”

Abstract-Structural properties of anhydrous Nb5+ -niobates and Ta 5+ -tantalates have been evaluated with the help of classic polyhedra approach and atomic net model. X-ray photoelectron spectroscopy (XPS) is utilized as a powerful method to determine the binding energy (BE) of individual atoms in the crystal lattice. Chemical bonding effects are discussed for niobates and tantalates using the binding energy differences Δ Nb = (BE O 1s -BE Nb 3d 5/2 ) and Δ Ta = (BE O 1s -BE Ta 4f 7/2 ) as key parameters to relate structural and electronic properties of the compounds with pronounced dielectric nature. Photocatalytic materials such as Sr 2 Nb 2 O 7 , Ta 2 O 5 , LiTaO 3 , and Sr 2 Ta 2 O 7 are considered in particular.
