“…At 7 km, Wang et al (2012) report persistence of the anchizone and temperatures range 200–270°C, with a 348°C outlier. Taken together, these P–T conditions are closer to those in Carlin‐type gold deposits (Berger et al, 2014; Cline et al, 2005; Hofstra & Cline, 2000; Radke & S., 1985) than to those in higher grade orogenic belts (Finch & Tomkins, 2017; Tomkins, 2013) and is supportive of the model described by Large et al (2011) for Carlin‐type and some orogenic gold deposits.…”

A comparative study of quartz vein‐hosted gold occurrences associated with Palaeozoic metapelites in two areas of Wales and Spain combines new, previously unpublished and published data. Metamorphic grade is greenschist in both areas, but very low‐grade indicators in the host metapelites distance the environment from the greenschist/amphibolite transition zone required for some orogenic gold occurrences. Basin fertility for Au is indicated by the presence of auriferous pyrites in the protolith black shales in Spain. Only minor igneous activity has taken place in both study areas. Mineral parageneses are similar, with early sulphide phases characterized by As/Co and later auriferous phases by Cu/Pb/Zn sulphides. Mesozonal P–T conditions apply at deposition in both terranes. In Spain, mineralisation typically occurs in quartzites near to the metapelites, but not where the veins are in contact with them, and extensional faulting appears to be a stronger control over mineralisation than geochemical interaction with metapelite wall‐rocks. In Wales, both structural and geochemical factors (C content of the wall‐rocks and coupled oxidation of NH4 ions substituted in wall‐rock phyllosilicates to produce CH4 and N2) could have a role in Au deposition. In both areas, minor cross‐fault systems between larger faults are typical hosts of the mineralisation. Assignment is made to different subtypes of the orogenic gold model but these subtypes share the characteristic of a local source. This has implications for exploration methodology in epizonal/anchizonal metapelite‐dominated terranes, where indicators of basin fertility for Au within the protolith itself assume importance.

“…Предполагается, что последние обеспечивали питание известковистых и алевропелитовых толщ углеродом и такими компонентами флюидных фаз, как Au, Ag, Cu, Ni, fe, As и т.п. Другие развивают представления о первичной (догипергенной) природе (порфировой, магматогенной, метаморфогенной) подобных благороднометалльных месторождений, но существенно преобразованных в зонах окисления [3][4][5].…”

“…В мире доля Au, полученного из упорных руд, составляет более 10%, главным образом из ме-сторождений карлинского типа в Неваде и Южном Китае [1]. В 2013 г. в Арктической зоне России (цен-тральная Чукотка) введено в эксплуатацию крупное месторождение золото-сульфидных вкрапленных руд (ЗСМВР) Майское, из руд которого к насто-ящему времени уже добыто более 15 т золота.…”
