Volcanology and Mineralisation in Volcanic Terrains

Date & Time

11 – 24 November 2022

This short course is a highly practical, field-based unit in which participants gain first-hand experience in the recognition, classification and interpretation of modern and ancient volcanic rocks. The course begins with studying well preserved modern and recent volcanic landforms, volcanic deposits and associated hydrothermal systems on the North Island of New Zealand (NZ). By visiting a range of spectacular field locations, participants gain insights into the processes and products of different eruption styles, contrasts in scale and structure of volcanoes, and the identification, description, logging and interpretation of key volcanic facies associations. Armed with an understanding of volcanic products and processes based on the inspection of NZ examples, where primary textural and compositional features are well preserved, participants travel to western Tasmania to inspect deformed and altered ancient (~500 m.y. old) volcanic successions of the Mount Read Volcanics and associated mineral deposits.

The first week provides an introduction to ore deposits, the minerals that occur within them, and key textures that help us to interpret ore genesis and that can aid exploration. You will learn how to construct mineral paragenesis for a variety of deposit types and become familiar with the tools used to identify and map alteration mineralogy and zonation patterns. Geochemical sampling and data analysis will also be reviewed. Week 2 covers metal zoning in hydrothermal ore deposits, describing and interpreting ore-related breccias, supergene processes and geochemical exploration in the regolith, geophysical properties of ore deposits and the economics of Economic Geology

This short course has a strong focus on field observations and hands-on practical skills, supported by an understanding of theoretical aspects. The short course presenters have detailed knowledge of the areas and deposits visited and are uniquely equipped to deliver the skills and insights needed by participants.

Course fees include all accommodation, field transport, entry fees, course notes, field guide, and most meals. Travel to and from NZ, accommodation in Hobart, and alcohol are not included in the course fee and are the responsibility of each participant. A valid passport is required for entry into NZ and Australia, and it is the responsibility of each participant to determine whether they require a visa, and to obtain that visa before travel.
