Gold production in Fairview Mine in the Barberton Greenstone Belt, South Africa, is focused on high-grade, steeply plunging ore shoots contained within a gently undulating system of spaced, low-displacement, broadly bedding-parallel faults, and shear zones, collectively referred to as the Main Reef Complex. This shear zone system is …

existing barren quartz veins play in gold ore genesis. The significance of these results in terms of relationships in other orogenic gold deposits globally is also examined. ... Utilization of pre-existing competent and barren quartz veins as hosts to later orogenic gold ores at Huangjindong gold deposit, Jiangnan Orogen, southern China ...

However, the exploration for and delineation of disseminated gold ore bodies is complicated by the dispersed nature of ore and alteration minerals and the lack of well-defined controlling structures. Hence, the actual controls of the mineralization often remain somewhat elusive ( Phillips, 1985, Teagle et al., 1990, Knight et al., 1993 ...

2 Altmetric. Metrics. Gold leaching from ore using iodide-iodine mixtures is an alternative to gold cyanidation. This study evaluated the ability of iodide-oxidising bacteria to solubilise gold ...

Due to a combination of low mean stress, limited fault displacement and over-pressured auriferous ore-fluid during deposit formation (e.g., Cox, 2005), only the most competent units in the rock sequence fail above the brittle-ductile transition, providing enhanced permeability for fluid flow and gold deposition. The specific rock units that ...

Gold-rich pyrite formed by dissolution of dolomite and sulfidation of its contained Fe. Where dissolution and replacement were complete, ore-stage pyrite and other insoluble minerals were all that remained. Locally, these minerals accumulated as internal sediments in dissolution cavities to form ore with gold grades >400 g/t.

The selected vein is 1 cm wide and parallel to the main mineralized vein population which strikes 070 and dips 70° to the SE.
