Abstract:

Sphalerite is an abundant mineral in the hydrothermal deposits from the Baia Mare and Oaș areas (northwestern Romania). Sphalerite samples were analyzed with an electron probe microanalyzer and Raman spectroscopy. The obtained results indicated different amounts of Fe in the various deposits from the Baia Mare and Oaș areas. The sphalerites from Baia Sprie, Cavnic, Iba, Turț Penigher, and Breiner have a low Fe wt.% content. High Fe wt.% contents are at Herja and partly at Ghezuri and Nistru (copper stage) where sphalerite is associated with pyrrhotite. The correlation between iron and zinc fro

Abstract Big Syncline is one of the few unexploited deposits of the Aggeneys-Gamsberg Ore District of the Northern Cape Province of South Africa and comprises Zn &gt; Pb &gt; Cu mineralisation. Future exploitation of this deposit requires a good understanding of the mineralisation textures and mineralogy for beneficiation purposes. Two of the most commonly occurring mineralisation types at Big Syncline, the mineralised pelitic schist (PEL) and garnet-magnetite-associated mineralisation (GM), are investigated with regards to sphalerite petrography and mineralogy and their potential impa

In the synthetic chalcopyrite disease in Fe-bearing sphalerite formed by a replacement reaction, chalcopyrite occurs as fine lamellae, which are also observed in relatively Fe-rich growth bands of the natural zoned sphalerite.

High-resolution S L3,2-edge XANES spectra have been collected from a series of high-quality sphalerite samples. Each of the sphalerite samples examined has a characteristic iron concentration, and the range is from <0.01 to 14.79 wt% Fe. The structures of the S L3,2-edges are investigated by comparing ab initio calculated spectra with experimentally measured S L3,2-edge spectra collected from synthetic ZnS sphalerite. The theoretical and experimental data provide evidence that S 2p electron transitions to empty S 3s and S 3d states can occur across an energy range above the absorption edge.

The main goal of this paper is to determine the order of the paragenetic sequence and phase transitions of the Ni–Fe sulfide association hosted in listvenites. Listvenites are hydrothermally altered mafic and ultramafic rocks that are often associated with active tectonic settings, such as transform faults, suture zones, and regional extensional faults, usually in contact with volcanic or carbonate rocks. Listvenitization is displayed by a carbonation process when the original olivine, pyroxene, and serpentine group minerals are altered to Mg–Fe–Ca carbonates (magnesite, calcite, dolomite, and
