most massive ore contains more than 50 percent sulfide minerals. Sediment-hosted ore commonly is intimately associated with igneous intrusions in the sedimentary rocks. Emplacement of these intrusions triggered ore formation and they host polymetallic veins and disseminations that contain iron, lead, zinc, and copper sulfide minerals. Some
CITATION: Barnes, S.., et al., 223, Role of volatiles in intrusion emplacement and sulfide deposition in the supergiant Norilsk-Talnakh Ni-Cu-PGE ore deposits: Geology, v. XX, p.
The observed sulfide size distribution between the central and marginal areas of the Valmaggia pipe is principally due to the dynamics of the magma upon emplacement, and may locally record the role of water- and carbon dioxide–bearing volatiles in the physical entrainment of dense sulfide liquids.

The Nova-Bollinger Ni-Cu sulfide deposit is associated with a small chonolith (tube-shaped) intrusion emplaced at lower crustal depths into granulite facies migmatite gneisses. The deposit comprises disseminated and net-textured ores within the intrusions and a high proportion of massive, semimassive, and breccia exocontact ores within the …
Lead sulfide test (or Lead acetate test) is a biochemical test for the detection of amino acids like cysteine and cystine. The test is a specific test for the detection of amino acids containing sulfur, S-S group in cysteine, and S-H group in cystine. The test is also called a lead acetate test as the reagent for the test is lead acetate.

Some of the globular ores show an association of sulfide blebs with clinopyroxene-carbonate intergrowths that may represent infilling of original CO 2-rich vapor bubbles. The exocontact ores have an assemblage of textures indicative of emplacement into hot, soft country rocks at a large-scale melting-infiltration front.

1. Introduction. Zinc sulfide minerals such as sphalerite (ZnS) are the main resources for zinc extraction (Santos et al., 2016).Globally, more than 70 % of zinc is produced from sphalerite (Chen and Dutrizac, 2004), which is often associated with other sulfide minerals such as galena, chalcopyrite, and pyrite (Aydogan et al., 2005).In the …

Abstract. In several papers published since 1954 by one of us, suggestions have been made concerning the genesis of a certain class of lead-bearing sulfide orebody of the conformable type. Such deposits are thought to have been derived from seaboard vulcanism and to have been emplaced in off-shore, largely volcanic, sequences, during ...
To this end, a lead sulfide unit cell with Fm-3 m(225) symmetry is converted to a 1 nm spherical nanocluster, and then is placed into a 2 nm supercell structure. Total density of state (DOS) and partial density of states (PDOS) are considered to study electronic properties. The highest energy level of the valence band and its lowest energy ...
Fractional crystallization of the sulfide liquid during emplacement resulted in the primary segregation of a Cu-rich residual liquid that migrated away from the bulk of the Fe-Ni sulfide, accounting for the high bulk Ni/Cu ratio, with the potential for the accumulation of a separate and thus far undiscovered Cu orebody.
Lead ore is primarily composed of lead sulfide (PbS), which is the most common mineral form of lead. Other minerals that may be present in lead ore deposits include cerussite (lead carbonate, PbCO3), …

Abstract. Although several deposit types have either been shown or suggested to be associated with paleokarst features in carbonate rocks, lead—zinc sulfide deposits of the "Mississippi Valley-type" (MVT) have received the most research and exploration. MVT deposits are not simply sulfide-filled open caves; rather, they are emplaced in ...
