Geology of the Brookbank gold deposit Download PDF EPUB FB2
The Brookbank gold prospect belongs to a third group of related gold deposits that formed along dextral shear zones localized at contacts between panels of metasedimentary and metavolcanic rocks. The Brookbank prospect occurs along a steeply dipping shear zone at the contact between footwall polymictic conglomerate and hanging-wall calc Cited by: 2.
Another example is the giant copper-gold-uranium deposit at Olympic Dam, South Australia, discovered beneath m of cover using an exploration program based on models developed by Western Mining Corporation geologists for Zambian copper belt-type deposits. Gold deposits are widely dispersed throughout many geologic settings and in virtually.

6, p. 1. Introduction. The genesis of vein-type to disseminated gold deposits, broadly classified as orogenic gold deposits (Groves et al.,Goldfarb et al., ) has remained genetic models for these deposits were evaluated in a recent review by Goldfarb and Groves ().Much attention has been focused on the source of auriferous fluids.
Although there are about twenty different gold minerals, all of them are quite rare. Therefore, most gold found in nature is in the form of the native metal. Gold occurs in hydrothermal veins deposited by ascending solutions, as disseminated particles through some sulfide deposits, and in placer deposits.
Petrogeologist study geology to find mine, coal, or oil deposit. Geophysics scientist study geology for recognize the physical characteristics of Earth component such as magnetism, seismicity, elasticity, Earth thermodynamic, by physical experiments in a specific geological structure which consist of.
At Hardrock, the gold mineralization is typical of Archean epigenetic hydrothermal gold deposits. The gold is hosted within BIF, porphyry and clastic sedimentary rocks proximal to the regional ductile high-strain Bankfield – Tombill fault.

focus on gold mining, reinforces the fact that there is a wide diversity in gold deposit types. There is a need to summarize such information and, more importantly, to attempt to synthesize it into a coherent classifica-tion of gold deposits.
The purpose of this paper therefore is to present a. Gold is mainly found in two types of deposits: lode (hard rock veins) and placer (surface).
Locating the richest gold bearing areas primarily involves research, planning, dedication and funds. In other words, those who study geological surveys, land formations, rock structures and gold prospecting history prior to prospecting may have a better.

A placer deposit is a concentration of a natural material that has accumulated in unconsolidated sediments of a stream bed, beach, or residual deposit.
Gold derived by weathering or other process from lode deposits is likely to accumulate in placer deposits because of its weight and resistance to corrosion.

Most mineralized occurrences in the Hardrock deposit area lie in a zone of deformation to the immediate north of, and genetically linked to, the Tombill-Bankfield Deformation Zone.
Gold deposits in the Hardrock deposit area are examples of epigenetic non-stratiform banded iron-formation-hosted gold deposits (Brousseau et al., ).
