The Features of Native Gold in Ore-Bearing Breccias with Realgar-Orpiment Cement of the Vorontsovskoe Deposit (Northern Urals, Russia)

This paper describes native gold in ore-bearing breccias with realgar-orpiment cement from the Vorontsovskoe deposit (Northern Urals, Russia). Particular attention is paid to morphological features of and its relation other minerals. The latter include both common (orpiment, barite, pyrite, prehnite, realgar) rare species (Tl Hg sulfosalts, such as boscardinite, dalnegroite, écrinsite, gillulyite, parapierrotite, routhierite, sicherite, vrbaite, etc.). general geological geochemical patterns Turyinsk-Auerbakh metallogenic province, including presence small non-economic copper porphyry deposits trend change composition (an increase fineness high-temperature skarns low-temperature breccias) confirm that an integral part a large ore-magmatic system genetically associated formation Auerbakh intrusion.
