“…A number of authors have conducted systematic analyses of all trace elements in sphalerite from various types of zinc deposits (volcanogenic massive sulphide (VMS), Mississippi Valley Type deposits (MVT), sedimentary exhalative deposits (Sedex), etc.) [4,5]. Amongst sphalerite ores, Mississippi Valley Type (MVT) deposits are a major source of Zn.…”

Characterization of Germanium Speciation in Sphalerite (ZnS) from Central and Eastern Tennessee, USA, by X-ray Absorption Spectroscopy

et al. 2017

X-ray absorption near edge structure (XANES) spectroscopy was used on zoned sphalerites (ZnS) from two world-class Mississippi Valley Type deposits, the Central and Eastern Tennessee Mining district, USA, in order to investigate germanium oxidation states. Due to the low germanium concentrations of these samples, it was necessary to perform the X-ray absorption spectroscopy (XAS) in fluorescence mode. The overlapping of the Zn Kβ and Ge Kα emission lines meant that a high energy-resolution was required. This was achieved using crystal analysers and allowed a bandwidth of 1.3 eV to be obtained. Experimental spectra were compared to XANES calculations and three configurations of germanium incorporation into sphalerite were identified. The first two, the most prevalent, show germanium (II) and (IV) surrounded by sulphur atoms in tetrahedral coordination, suggesting the replacement of Zn by Ge. In the third configuration, germanium (IV) is surrounded by oxygen atoms. This third configuration is unexpected for a zinc sulphide mineral and it resembles that of argutite (GeO 2 ).

“…% Sn in sphalerite from the Logatchev submarine hydrothermal field (and assigned it to stannite inclusions), Mid-Atlantic Range, and Ono et al [54] measured 1.8-4.3 wt % Sn in sphalerite from polymetallic mineralization at the Suttsu vein-type deposit in Japan. Sphalerite analyzed by LA-ICP-MS at various base metal bearing deposits from South China [52], revealed very low Sn content (up to 10 ppm), only in one deposit (e.g., the Bainiuchang VMS deposit) the Sn content in average 1130 ppm, but this could be due to the small size of the Sn-bearing minerals. Cook et al [51] summarized the LA-ICP-MS trace element data of sphalerite and indicated that Sn content is very low in samples from skarn and It is suggested here that sphalerite and stannite group minerals in Kosovo precipitated simultaneously during cooling of the hydrothermal fluids, as indicated by the wide range of the obtained temperatures.…”

Sn-Bearing Minerals and Associated Sphalerite from Lead-Zinc Deposits, Kosovo: An Electron Microprobe and LA-ICP-MS Study

Stannite group minerals (ferrokësterite and stannite) occur in small amounts in association with sulfides in hydrothermal Pb-Zn deposits in Kosovo. The chemical composition of sphalerite co-existing with Sn-bearing minerals has been investigated using laser ablation inductively-coupled plasma mass spectrometry (LA-ICP-MS). Flat Sn-spectra suggest that Sn is bound in the sphalerite lattice or as nanoincluions. Sphalerite from Stan Terg, overgrown by ferrokësterite, contains the lowest Sn content (few ppm) and have been precipitated before Sn-enrichment in the fluids. The highest value of Sn (520 ppm) of Stan Terg sphalerite was obtained directly close to the ferrokësterite rim, and indicates a rapid increase of Sn in the hydrothermal fluids. Significantly higher values of Sn in sphalerite were obtained from other deposits: 1600 ppm (Artana), up to 663 ppm (Kizhnica), up to 2800 ppm (Drazhnje). Stannite-sphalerite geothermometry revealed the following ore-forming temperatures for the Kosovo mineralization: 240-390˝C for Stan Terg, 240-370˝C for Artana, >340˝C for Kizhnica, and 245-295˝C for Drazhnje. Sphalerite and stannite group minerals precipitated simultaneously during cooling from reduced hydrothermal fluids and under low-sulfidation fluid states. Fluctuations in physico-chemical fluid conditions are evidenced by the presence of stannite group minerals along growth zones in sphalerite and may be related to short interval of magmatic pulses during ore deposition.

“…The minor and trace elements in sphalerite have application in identifying genetic ore types and the sphalerite temperature of formation [42,43]. Our EPMA data from the Chashula deposit show that the Hg contents of sphalerite I in the Hg-Zn ores (0.00-0.30 wt % Hg) are lower than in the outer Zn ores (0.01-1.31 wt % Hg), while the Hg contents of sphalerite II in the Hg-Zn zone are very Hg-rich (up to 22.26 wt % Hg).…”

Among the Zn-Hg-S and Hg-Se-S series minerals, Hg-bearing sphalerite and metacinnabar are uncommon in ore deposits, but they are useful indicators of temporal variation of ore forming fluids, as well as presenting metallurgical implications for Hg-bearing deposits. To understand the Hg-Zn-Se mineralization system of the Tongren-Fenghuang Hg Belt (TFHB), the Zn-Hg-S and Hg-Se-S series minerals of the Chashula Hg-Zn and Dongping Hg-Ag-Se carbonate-hosted deposits were studied by microscopic observation, electron-probe microanalysis, and X-ray diffraction analysis. Observations show that the Chashula and Dongping deposits experienced two stages of mineralization (Stages 1 and 2). The pyrite, sphalerite I (Hg-poor sphalerite), and quartz formed in Stage 1, while the Zn-bearing cinnabar, sphalerite II (Hg-bearing sphalerite), cinnabar, selenium metacinnabar, and Ag minerals formed in Stage 2. The Hg-bearing sphalerite, containing 13.36-22.26 wt % Hg (average 18.73 wt % Hg), replaces sphalerite I (0.00-1.31 wt % Hg). The Hg-bearing sphalerite of the Dongping Hg-Ag-Se deposit contains lower Hg (10.12-14.67 wt % Hg) than that of the Chashula deposit. The unit cell a of the Hg-bearing sphalerite gradually increases with increasing Hg content. The texture of the Zn-bearing cinnabar shows it is not stable and easily breaks down to Hg-bearing sphalerite and cinnabar through the chemical reaction: (Hg,Zn)S → (Zn,Hg)S + HgS. Selenium metacinnabar intergrowths with tetrahedrite and miargyrite were found only in the Dongping deposit. The selenium metacinnabar contains 76.57-83.97 wt % Hg, and extensive isomorphic substitution of .21 wt % Se, 4.14-10.32 wt % S). Based on our mineralogical studies, the Zn, Hg, Hg-Zn, and Hg-Se mineralization styles in the TFHB are interpreted as the product of different stages in the mineralization process.
