Volcanology and Mineralisation in Volcanic Terrains unit (KEA708)

Hobart

Introduction

This predominantly field-based unit provides up-to-date reviews of approaches to (i) mapping, (ii) facies analysis, and (iii) understanding mineralisation processes in volcanic terrains. The centrepiece of the unit is a 14 day fieldtrip (10 days on the North Island of New Zealand and four days in Tasmania) examining both modern and ancient volcanic successions. On the New Zealand leg of the fieldtrip students learn about differences in the scale and structure of volcanoes and the processes and products of different eruption styles. In the relatively young, well preserved and beautifully exposed volcanic rocks of New Zealand, students learn to identify, describe and interpret volcanic facies and facies associations in volcanic rocks formed in both both subaerial and submarine environments. The characteristics of low-sulfidation epithermal deposits formed as a result of subaerial, syn-volcanic, hydrothermal activity are discussed and examined during a visit to the Waihi gold mine. Visit to the world-class geothermal fields and/or Waihi epithermal Au deposit. The second part of the unit - delivered in Tasmania - examines variably altered, deformed and metamorphosed Cambrian volcanic rocks of the highly mineralised Mount Read Volcanic Belt. Students learn skills and strategies to help "see through" the effects of later geological events, in order to decipher original volcanic textures and facies associations. These skills are used to classify and interpret the host-rocks and depositional settings to some of the world-class volcanic-hosted massive sulfide deposits of the Mount Read Volcanic Belt. These deposits were formed by syn-volcanic hydrothermal activity at or near the seafloor, approximately 500 million years ago. In addition to the 14-day field trip, there is a post-field trip assignment. The unit Volcanology and Mineralisation in Volcanic Terrains may be taken as a either (i) a CORE OPTION unit (choice between KEA707, KEA708 and KEA718) at the Mastery 1 level, or (ii) an OPTION unit at Mastery 2 level of the Master or Economic Geology degree.

Note

Please check that your computer meets the minimum System Requirements if you are attending via Distance/Off-Campus.

Units are offered in attending mode unless otherwise indicated (that is attendance is required at the campus identified). A unit identified as offered by distance, that is there is no requirement for attendance, is identified with a nominal enrolment campus. A unit offered to both attending students and by distance from the same campus is identified as having both modes of study.

Learning Outcomes

• Describe, name and classify volcanic rocks and volcano-sedimentary facies using appropriate descriptive conventions and non-genetic terminology
• Differentiate the various primary and alteration-related processes responsible for clastic textures in volcanic rocks
• Formulate or evaluate mineral exploration strategies based on a literature review or primary appraisal of the characteristics, facies associations, volcanic settings and alteration-related textural features of volcanic and volcano-sedimentary rocks
• Explain volcanic, volcano-sedimentary and associated mineralisation processes to an audience of industry or academic peers using appropriate volcanological terms and concepts.

Teaching

Teaching Pattern	This unit is based around a 14 day fieldtrip to the North Island of New Zealand (10 days) and western Tasmania (4 days). Activities during the fieldtrip average ~12 hrs/day. The unit also involves pre- and post-fieldtrip assignments constituting ~75 hrs individual study completed over 4 week periods in the lead-up to, and following, the fieldtrip.
Assessment	AT2 Field based exercises Western Tasmania (20%)|AT1 Field based exercises New Zealand (40%)|AT3 Post-field trip report (40%)
