Peralkaline granite Granite is a mediumtocoarsegrained acid igneous rock with essential quartz (>20%) and feldspar, where alkali feldspar constitutes between 100 and 35% of the feldspars, and minor mafic minerals. Hornblende and biotite are the commonest mafic minerals, however, muscovite is also frequently encountered.

In the veins most native gold is associated with arsenopyrite, but in the granite it occurs as microscopic inclusions within the pyrite. Various geothermometers and paragenetic relations suggest that vein gold deposition occurred during the end stages of mineralization at temperatures between approximately 200 degrees and 300 degrees C, at pressures between 670 and 2,500 bars, and at depths
