Thus iron pyrites which is such a frequent constituent of mineral veins is converted into hydrated oxide of iron and a vein originally consisting of iron pyrites and quartz becomes a honeycombed brown and yellow rock the removal of the iron pyrites in the form of a soluble sulphate leaving cavities which are only partly filled up by oxide.
Quartz occur with spurs of copper carbonate and oxide and pyrites between the laminre of the slate strata and the ground here is wetIn the end of the tunnel the slate beds containing iron pyrites dip to the north-east.
While quartz veins containing copper pryites and the richer sulphide ores such ascopper glance and erubescite are the most common deposits there are other typesIn the dania mine nondweni a mixture of iron pyrites copper pyrites and zincblende with little quartz forms a great portion of the deposit but in places the sulphideshave.
