the metabasalts and is of polymetallic type containing copper, zinc and lead with some silver and gold values. The principal sulphide minerals are chalcopyrite, pyrrhotite, pyrite andsphaleritewithminorgalena. The has been explored by 45 boreholes drilled by GSI and the Department of Mines and Geology, Government of Size: KB. An Inferred and Indicated Resource for the high grade zone was then estimated to be t at an average uncut grade of g/t gold (for contained oz) or g/t gold after a top cut to 80 g/t gold, within a total Inferred and Indicated Resource of t at an average uncut grade of g/t gold, equal to contained oz.
Introduction Classification of hydrothermal vein deposits Classification of hydrothermal gold deposits Hydrothermal gold deposits in Archaean terrain Exploration for gold in Archaean terrain Concluding statement References These greenstone rocks contain copper and zinc and are bestowed with gold occurrences, the latter often in enriched forms in zones of high strain. The best known sulphide mineralisations, volcanogenic and sediment-hosted, are located in Proterozoic fold belts and in the intracratonic Proterozoic basins within the BGC and are related to.

Mineral Deposits Division.; Canadian Institute of Mining and Metallurgy. Geology Division.;]. The Yilgarn Craton is a large craton that constitutes the bulk of the Western Australian land mass. It is bounded by a mixture of sedimentary basins and Proterozoic fold and thrust belts.
Zircon grains in the Jack Hills, Narryer Terrane have been dated at ~ Ga, with one detrital zircon dated as old as Ga. The Murchinson Province of the craton contains the oldest dated. For the first time in the history of the Earth in the late Archean greenstons belts, widespread occurrence have received sulphide ore deposits of copper, zinc, gold, silver and cadmium.
Most ancient among them is the copper-zinc deposit Khuntoushan (3, Ma) on the north of China. Metallogeny of Gold in the Precambrian of Northern Europe Article in Economic Geology 98(7) November with 97 Reads How we measure 'reads'.
The term ‘greenstone’ was also used by T.L. Baines () in his book ‘The Gold Regions of South Eastern Africa’ to describe metamorphosed hornblendic and schistose rocks hosting gold-quartz veins in Rhodesia – a region now known as Zimbabwe (Hunter and Stowe, ).
Greenstone belts have also been used synonomously with ‘schist Cited by: Request PDF | A Special Issue Devoted to Base Metal and Gold Metallogeny at Regional, Camp, and Deposit Scales in the Abitibi Greenstone Belt: Preface |. This approach was known as the “source bed concept” and was used to explain volcanogenic hosted massive sulfide copper–zinc–(lead, silver, gold) deposits until the s, when geologists discovered that they were in fact syngenetic.
The shear zone model was developed over years ago and saw resurgence only with the rise in gold. Based on the spatial-temporal distribution of different rock series and the spatial distribution of varied metamorphic grades of the Neoarchean in different regions of the Eastern North China craton, we propose that the craton can be divided into four blocks, i.e., the Lushan-Jiaobei, Zhongtiao-Taishan, Liaonan-Qingyuan, and Wutai-Zunhua by: 4.

As gold is an important commodity in greenstone belts, twelve gold anomalies were identified on the Giyani sheet. One of the gold anomalies that was conspicuous was the Louis Moore anomaly (No.

In this chapter I discuss and describe a range of hydrothermal mineral systems that are generated at passive margins, in basin structures of intracontinental or back-arc rifts, with or without obvious connection to igneous activity, seafloor metalliferous sediments and iron and manganese oxide by: 3.
