### Geology of Gold

Location: School of Earth Sciences, The University of Melbourne, and
Fosterville area (VIC)

Enrolments:

Dates: 14-18 March 2022

Times: 09:00-17:00 each day.

This is a 5-day course of lectures, practical sessions and a field trip, devoted to the Geology of Gold. The course provides a broad coverage of gold geology and exploration, as well as some of the latest research ideas and how they apply to mineral exploration. The course is suitable for Honours and postgraduate students, and for geologists in the mineral industry with some exploration and mining experience. The course is also suitable for government geologists involved in field areas where gold potential exists and who are seeking to relate their work more closely to industry.

The course covers all major types of gold deposits with emphasis on Archean greenstone and sedimentary rock hosted deposits. The course covers both conventional thinking on different deposit types, and novel ideas with their exploration implications. A two-day field trip ventures into the Victorian gold province and includes visits to the major Fosterville mine, Deborah Mine and a fieldwork exercise at Victoria Hill. Geochemistry, structural geology, regolith and deposit geology are covered at a level to enable participants to take their place comfortably in industry and government teams. An emphasis of the course is on a holistic approach that uses all applicable fields of geology to address the questions pertaining to gold.

The course opens from 8.30am for a 9.00am start on Monday 14th March with the field trip leaving from the university on Wednesday 16th March with a late return on Thursday evening. Lectures resume on campus on Friday 18th of March.

Note: The main entry doors to the Earth Science Building are located one level above the road and are accessed via the stairs or ramp from Elgin Street, or from the bridge across Swanston Street.

### Ore Deposit Models

COURSE INFO:

This course will not be offered in 2022!

Understanding of rock types, textures, geochemical and alteration signatures within the context of an ore deposit model is a key skill for any geologist planning a career in either minerals exploration or economic geology research. Development of the underpinning ore deposit model requires integration of multilayer datasets, generated at a range of scales (both spatial and temporal), using a variety of techniques. Also required is a keen understanding of diverse but interrelated ore forming processes: e.g. magmatism, basin evolution, hydrology, permeability-porosity generation and evolution.

This course is led by a group of world-leading researchers, providing an overview of the key features of several major classes of economically important mineral deposits, VHMS, porphyry Cu-Mo-Au, epithermal Au, skarn, IOCG, SEDEX, sediment-hosted stratiform Cu, sediment-hosted and orogenic Au. Each deposit style will be discussed in terms of geological and tectonic framework, mineralisation, alteration, genetic models and exploration criteria. Lectures covering each deposit type will be complemented with exercises or practical classes which examine sample sets of typical ores, host rocks, and geochemical signatures.

The course is classroom-based, run over five days (9.00am to ~6.00pm) from Monday 10th May until Friday 14th May 2021. It will be held at the Centre of Excellence in Ore Deposits (CODES), University of Tasmania, Sandy Bay campus in Hobart.

Industry participants may choose to attend on a daily basis, but must confirm which days they plan to attend with Angela Escolme.

Minimum enrollments: 10; Max 20

### Practical Igneous Petrology

Hosted by: University of Tasmania

Dates: 30th of May - 03th June 2022

Venue: Codes Conference Room, Geo353; Geology/Geography Building, Sandy Bay Campus; Course starts at 9 am

The course is intended for Honours students and other Post-Graduate students with an interest in the formation and evolution of basic and ultrabasic magmas . For those interested in magmatic ore deposits, it is recommended that this course is taken in conjunction with the "Igneous Geodynamics and Magmatic Ore Deposits” course taught at the University of Melbourne.

The first two days cover key theoretical aspects of petrology including units of concentration, solid solutions and mineral formulas, activities and equilibrium, the phase rule, mass balance, phase diagrams, equilibrium/fractional crystallisation.

The third day includes an example of a large layered intrusion (Dovyren Magmatic Complex, Siberia), followed by: the effects of pressure and H2O on melting and crystallisation; causes of melting and crystallisation; and an introduction to the concept of distribution coefficients for trace elements.

Day four covers trace elements in main rock-forming minerals, modelling of crystallisation process, several aspects of petrogenesis and mineral chemistry of MORBs and subduction-related lavas.

Day five will introduce studies of melt inclusions and present examples from subduction-related lavas and komatiites.

Each day will consist of 3 lectures (~1 hour each), each followed by 1-hour practicals on the subject of the preceeding lecture. Each practical will be assessed, and an average of three daily practicals will be given as a mark for each day. The mark for the course is the average of the five daily marks.

The course is held in Hobart at the University of Tasmania. Directions on how to find the venue will be provided to the enrolled students.
