Structural similarities of some secondary lead minerals
نویسنده
چکیده
Some structural analogies found in tsumebite, vauquelinite, forns.cite, and brackebuschite make it possible to place these secondary lead minerMs in the s~me series with general formula Pb~MeII(Z)(XQ)(Y04), where MelI is a bivalent cation as Cu 2+ or Mn 2+, Z is the hydroxyl group or the w~ter molecule, X is S, Cr, or V, ~nd Y is P, As, or V. Some crystallochemical considerations are developed in order to explain how the replacement of these elements affects the crystM structure in these substances.

Electron-probe microanalyses and scanning electron microscopy of chrornitites from some ultramafic members of Neyriz ophiolite indicate that sulifides of platinum- group minerals (PGMs) occur as solid inclusions in chromite grains. Laurite with the general formula of (Ru ,Os ,lr ) S , and erlichmanite are the main identified sulfide phases. The PGMs occur as 4 to 20 microns euhedral to rect...

The oxidation of sulfide minerals in coal and mine's waste materials produce acid mine drainage. The evaporation, oxidation, dilution and neutralization of this acid drainage lead to formation of secondary minerals. Due to having broad surface spreading these minerals have the potential of maintaining sulfates and many of the metallic elements. In order to carry out mineralogical and geochemica...
