Geochemical identification of episodes of gold mineralisation in …
The morphology and mineral chemistry of gold and associated sulphides at Sheba, Fairview, and New Consort gold mines in the Barberton Greenstone Belt (BGB) identify two main types of mineralization. The first type occurs associated with sulphides (mainly pyrite), either as inclusions (10–30 μm) or as sub-microscopic gold. The second …

The thick-bedded, competent quartzose sandstones, conglomerates, and siltstones of the Moodies Group (<3,225 Ma) influence structural style in the ∼3.1–3.5 Ga Barberton Greenstone Belt. Moodies Group rocks are folded into a train of tight, subparallel, doubly plunging, overturned synclines separated by narrow, strike-parallel fault zones.

In the Montrose Farm area (25 km SW of Barberton) Series of the Swaziland System show similar deformations as the essentially younger series of the Moodies System. Thrustfaults with desplacements of more than 1000 m are developed more often than formerly assumed. The brittle to plastic behaviour of banded cherts is due to a different content of gelic SiO2 …

Felsic igneous rocks within the 3.3‐ to 3.5‐Ga Barberton …
Felsic igneous rocks within the circa 3.5-Ga ophiolitic Onverwacht Group of the Barberton greenstone belt have traditionally been mapped as recurring volcanic units within a continuous stratigraphic succession. These felsic units have been interpreted as part of several mafic to felsic volcanic cycles making up this succession.

The latter have variously been interpreted as epigenetic (Phillips et al., 1984) and volcanogenic-exhalative (Anhaeusser, 1986a). The Lily deposit some 24 km northeast of Barberton (Fig. 1) offers a particular opportunity to study a gold deposit in ferruginous sediments at elevated metamorphic grade.

Trace element zoning of sulfides and quartz at Sheba and Fairview gold
Gold in greenschist-facies deposits of the Barberton Greenstone Belt is closely associated with arsenopyrite and pyrite, and is present both as "invisible" gold and as electrum inclusions (Cabri et al., 1989). In this study, we present data on the chemical zoning of sulfides and quartz in mineralised veins from the Sheba and Fairview mines.
