Rutile Enriched in Chalcophile Elements (Sb, Sn, Te), and ...

 · Abstract—The paper contains data on rutile, tripuhyite, and unusual Ti-rich cassiterite found in sublimates of active fumaroles at the Tolbachik volcano, Kamchatka, Russia. In contrast to rutile from other geological environments, fumarolic rutile is enriched in minor chalcophile elements. It contains up to (wt %): 35 Sb2O5, 59 SnO2, 11.3 TeO3, 1.9 CuO, 0.4 ZnO, and 18 …

 · This agrees with the indications in previous work on the formation of Sb 5+-enriched rutile-type solid solutions in Cr/(V)/Sb mixed oxides, . This excess Sb 5+ generated a corresponding amount of cationic vacancies and thus was responsible for the low crystallinity of these samples. On the other hand, positive effects were the high specific ...

Compositional Variability of Rutile in Hydrothermal Ore ...

Rutile is a relatively common accessory phase in many geological environments, and although it is almost always composed dominantly of TiO2, it is also associated with a wide range of minor and trace element substitutions. The most prominent minor elements that occur in rutile are Fe, Cr, V, Nb and Ta. Like Ti, the latter two elements are essentially immobile in most non …

However, it does not represent a distinct mineral species, as it is only a (Fe, Nb)-enriched but still Ti-dominant derivative of rutile. Moreover, niobian rutile is in most cases exsolved into a (Fe, Nb)-depleted rutile + titanian
