Diversity in Carlin-Style Gold Deposits

Abstract

Reviews in Economic Geology is a series publication of the Society of Economic Geologists designed to accompany the Society's Short Course series. Like the Short Courses, each volume provides comprehensive updates on various applied and academic topics for practicing economic geologists and geochemists in exploration, development, research, and teaching. Volumes are produced in conjunction with each new Short Course, first serving as a textbook for that course and subsequently made available to SEG members and others at a modest cost.

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

“…The significant amounts of Tl-containing ore minerals sharing the same paragenesis as native gold from breccias with realgar-orpiment cement in the Vorontsovskoe deposit also indicate a unique mineral gold ore assemblage that has no analogues among the deposits of the Urals. The presence of Tl-As-Hg-Sb-(Te) geochemical signature, including those belonging to the same paragenesis as gold, is also characteristic for Carlin-style gold deposits [22,23]. However, thallium minerals are also widely distributed in deposits associated with the metamorphosed carbonate strata composed of limestone and dolomite [24][25][26] with the formation of mineralized bodies according to the principle of alpine-type veins.…”

“…In general, the presence of thallium mineralization in ore bodies of different genetic types can be explained by actively developed models of the magmatic formation of Carlinstyle deposits [22][23][24][25][26][27][28][29][30][31][32][33]. Within these models, thallium mineralization can be localized at a maximum distance from the magmatic source in the zone of intermediate argillic alteration and the distance from the magmatic source can reach more than 5 km.…”

Genetic relationship between hydrocarbon system evolution and Carlin-type gold mineralization: Insights from ReOs pyrobitumen and pyrite geochronology in the Nanpanjiang Basin, South China

“…Differences between the Carlin-style deposits in Nevada and other similar deposits worldwide have led to a proliferation of terms, including Carlin-type, Carlin-like, sedimentary rock-hosted and distal disseminated, gold deposits. Characteristics including tectonic setting, host rocks, gold occurrence, hydrothermal alteration, and ore paragenesis were used to define those types of gold deposits (Muntean, 2018b). Comparison of the gold deposits in Nevada and the Nanpanjiang Basin, South China, show that both groups of deposits have, (1) a similar tectonic evolution; (2) invisible gold residing in fine-grained (<10 μm) pyrite or within pyrite rims on gold-poor pyrite cores (Su et al, 2012;Cline, 2018;Yan et al, 2018); (3) host rocks consisting of limestone and/or calcareous siltstone; and (4) alteration assemblages that reflect sulfidation, decarbonatization, silicification, and argillization processes (Xie et al, 2018a).…”
