FT 4: Porphyry and Vein copper-gold Deposits in the Ordovician Macquarie Volcanic Province: Mineralisation in an Arc or a Rift?

FT 4: Porphyry and Vein copper-gold Deposits in the Ordovician Macquarie Volcanic Province: Mineralisation in an Arc or a Rift?

Participants on this field trip to the Ordovician porphyry copper-gold province of central NSW will gain a brief overview of the Macquarie Volcanic Province that hosts the operating Cadia, Northparkes and Cowal mines, and of these deposits themselves. The many unusual features of this province have led to both island arc and extensional rift settings proposed for the formation of both porphyry and vein deposits and both models will be discussed along the way. Preservation of mineral deposits over 450 Ma is just one of the intriguing features!

Inclusions

 

LEADERS: Dick Glen (Richard Glen Consulting) and Phil Blevin (Geological Survey of New South Wales)

Dick is Adjunct Professor at Macquarie University in Sydney, having retired as Senior Principal Research Scientist from the GSNSW in 2013. At the Survey, he worked on many regional mapping projects as well as mineral and energy framework studies, including joint Federal Government funded projects, such as the one with CODES, University of Tasmania (Tony Crawford and Dave Cooke) on the Macquarie Volcanic Province.

 

Phil is Manager – Mineral Systems at the Geological Survey of New South Wales with an interest in understanding how mineral systems work in both igneous and sedimentary rocks. Before that, he worked on government and industry-funded projects on granite fertility and on intrusion-related Cu-Au igneous rocks, and also consulted in Australia and overseas for industry and government agencies.
