Stable Isotopes and Ore Fluid Chemistry of Gold Mineralisation at Waitangi Deposit, Thames District, Coromandel Peninsula, North Island, New Zealand

摘要

The Thames gold-silver deposits are part of the Hauraki goldfield, situated within the Miocene to Pliocene calc-alkaline Coromandel Volcanic Zone (CVZ). The Waitangi vein system is one of the mineralised ore shoots in the Thames district. The Thames gold deposits are characterised by shallow-level epithermal vein mineralisation with phyllic to advanced argillic alteration assemblages and abundant sulphide minerals including pyrite, arsociation with sulphide minerals.
