The nature and origin of a granitoid-related gold deposit

Dargue's Reef is a mesothermal, gold sulfide deposit developed in altered granitoid rocks of the Braidwood Granodiorite in southeastern New South Wales, Australia. Two main lodes consist of narrow zones (0.6-9.5 m wide) of intense sericitic alteration and pyritization (15-30% pyrite), enclosed in areas of propylitic alteration.

Alteration paragenesis and the timing of mineralised

2017-12-1  1. Introduction. Archean gold deposits are commonly referred to in the literature as lode-gold deposits, because of the common presence of gold-bearing, quartz-carbonate veins (e.g., Robert and Brown, 1986b, Robert and Brown, 1986a, Groves et al., 1998, Goldfarb et al., 2005) with many good examples in the Kalgoorlie Terrane in the Yilgarn Craton of Australia (e.g., Groves et al., 1995

Hydrothermal alteration geochemistry of Nugget gold

2018-6-14  Abstract Ankeritic alteration zones are associated with gold mineralisation in the Nugget vein system, Shotover valley, northwest Otago. These zones consist of sheared and brecciated schist in Miocene normal faults. The zones are also extensively silicified. Mineralisation resulted from passage of low-salinity, low-CO 2 water at 200-250°C

Mineralized veins and breccias of the Cripple Creek

The Cripple Creek district has yielded nearly 21 million troy ounces of gold since its discovery in 1891. The orebodies occur as narrow veins within Precambrian and Tertiary rocks and as bulk tonnage deposits within tectonic and hydrothermal breccias.The district is localized within and adjacent to a 27.9- to 29.3 + or 0.7-m.y.-old nested diatreme-intrusive complex.
