Gold in quartz is one of the most collectable forms of natural gold. Unlike gold dust and nuggets, gold bearing quartz is still encased in the quartz rock, creating a natural high contrast display of beautiful gold with white quartz. Mineral collectors will gladly pay many times the gold value for certain specimens.

This can be an indicator of gold. Iron Staining & Gossans: Not all veins produce much quartz – gold bearing veins can consist of calcite or mostly sulfides – which often weather into iron stained spots when the pyrites convert to iron oxides. Large amounts of iron oxides like hematite, magnetite and ironstone can be favorable indicators.

In Nigeria, orogenic gold mineralization is mainly controlled by lithologies and geologic structures in the schist belts. The Kushaka schist belt exhibits gold mineralization mainly in veins and stockworks and in placer deposits found in eluvial and alluvial sediments [1,2,3,4,5,6,7].The Kushaka greenschist belt is a Neoproterozoic to early …

In the Pontal auriferous lode, dominant saccharoidal quartz is associated with oligoclase, biotite, hornblende, tremolite-actinolite, sulphides (less than 2%), and disseminated native gold. Four main types of fluid inclusion have been distinguished based on their habit, distribution and spatial relation-ship with gold particles.
