·Archaean gold quartz vein deposits are commonly hosted in high angle reverse shear zones and are interpreted to have formed in a regime of horizontal compression and high fluid pressure environment This paper presents the results of a combined structural and fluid inclusion study on three gold quartz vein deposits of the Val
There are a lot of important gold bearing quartz veins in the Xiaoqinling metamorphic core complex The quartz veins are strictly controlled by shear zones Stress analysis indicates that the metallizing process of the Xiaoqinling gold deposits of quartz vein type can be divided into two stages At the first stage the shear zones were formed in an extensional
·Epithermal gold deposits are among the richest gold deposits in the world with some bonanza grade ore shoots containing more than 1000 g/t gold equivalent or a kilogram of gold for everyone tonne of rock mined The tonnage of ore in epithermal veins is typically smaller than other types of low grade gold Gold mineralisation within
In addition Fool s Gold pyrite can contain gold Quartz can often be mingled with veins or nugget size pieces of gold One of the most famous and oft sought signs of the possibility of gold is the sight of white quartz This purer/richer form perhaps more exciting is found in veins At the surface of these veins the deposits tend to be
·The Charlotte gold quartz vein stockwork bounded by D4 dextral strike slip faults is separated in time by barren D3 thrusts from D2 pyrite telluride lodes located within the district scale Golden Mile Fault GMF A shear array of Au Ag fault fill veins in the GMF indicates sinistral strike slip during Golden Mile type mineralization
·The gold bearing quartz veins consist of up to four generations of quartz each deposited from a fluid of different composition and temperature Wilkinson et al 1999 Gold mineralization is hosted by the second and fourth generations of quartz Earls et al 1996; Wilkinson et al 1999; Parnell et al 2000 Views have changed on the genesis
