orogenic gold mineral assembly

Mines of Australia's Bendigo Gold Fields Geology for

The Bendigo Gold fields are not just, after Kalgoorlie, Western Australia, the second most productive gold mining area in Australia, but also a mineral discovery that literally shaped a nation. Since 1851, approximately 25,000 oz (777 tonnes) of gold has been extracted from Bendigo, initially from alluvial gold and later from underground mining of the gold bearing quartz reefs.

2.7 Orogenic mineral system Geoscience Australia

The orogenic mineral system (Figure 2.7.1) unites a diverse group of mineral deposits that form during orogenesis, and include lode gold and Cobar type Cu Au Zn Pb Ag deposits. These deposits form in response to major orogenic events caused by accretion or changes in subduction direction or dip.

Such an assumption is valid because this deposit type is, by far, the most dominant gold

On the source of orogenic gold Geology GeoScienceWorld

Gold has historically been a key strategic commodity, and the study of gold deposit formation has long been investigated. Debate on the genesis of so called orogenic gold deposits (>75% of gold recovered through history; Phillips, 2013), continues largely because it is difficult to reliably identify the source of gold.In this issue of Geology, Gaboury.

Mesothermal and Greenstone Gold Deposits AKA Orogenic

Mesothermal gold deposits form half way up through the rise of the melt from the deep crust to the surface usually at a depth of less than 10 km but greater than 1 km. temperatures at these depths are generally somewhere between 450 degrees and 250 degrees Celsius. The term mesothermal veins is really a sack term, referring simply to the depth formation.

Because of this, it is suggested that the gold ores simply be classified as `orogenic' lode types, as was originally suggested by Bohlke (1982). A remaining problem is whether to classify many `intrusion related gold deposits' within this group of orogenic gold deposits.
