Workshop 1
Gold Geology
Niel Phillips (OAM)
Sat 27 - Sun 28 June 2020
2 days
Day 1 - How gold deposits form, Day 2 - Application of gold geology to exploration - South African focus; This is a two-day workshop primarily for geologists interested in gold. The philosophy of the workshop, and indeed of the presenter’s career, is that improved geology is strongly correlated with improved exploration and mining outcomes. Day 1 covers much of the descriptive and genetic aspects of gold geology to set the platform for successful exploration and mining globally. Day 2 is focussed on South Africa. Both days provide case histories of exploration success from Australia in which the presenter has first-hand knowledge (e.g. Yilgarn Craton of the 1980s with 170 Moz Au discovered since 1980), in specific greenstone belts (e.g. Yandal gold province with several multi-million ounce discoveries in a new belt) and the high-grade Fosterville goldfield in a Paleozoic metasedimentary sequence now producing over 0.5 Moz per year above 30 g/t Au. The emphasis of this workshop is on the use of gold geology to identify prospective greenstone belts and sedimentary successions to give the confidence to acquire ground, raise funds and proceed with exploration.
Bio of the presenter: Professor Neil Phillips OAM: Neil Phillips graduated in geoscience from the University of Melbourne (BSc), Monash University (BSc Hons, PhD), and from Harvard Business School (Advanced Management Program). His thesis was on the metamorphism and geochemistry around Broken Hill, NSW. As a postdoctoral fellow at University of Western Australia, he co-founded the Archaean Gold Group in 1980 with David Groves, as they developed the geological principles so successful there in gold exploration. As a lecturer at the University of Witwatersrand in Johannesburg from 1984, he established research projects at all the operating Witwatersrand gold mines demonstrating the importance of regional metamorphism, gold-related alteration and auriferous fluids in all goldfields. He was subsequently made Professor of Economic Geology at James Cook University and developed the extended field programs in the Cloncurry – Mt Isa region. From 2001, he was Chief of the Division of Exploration and Mining during one of CSIRO’s transformational periods. As a consultant in Kalgoorlie for Minsaco Resources and then General Manager for Great Central Mines, he led the geological development of the Yandal gold province north of Kalgoorlie in a role that included teaching, research and mentoring with teams of mine and exploration geologists. He and Martin Hughes have had a long-term research project in the Victorian gold province identifying highest priority targets amongst the 7000 old mine workings: this work singled-out Fosterville goldfield – now producing at over 30 g/t Au. Honorary professorial appointments at University of Melbourne, Monash University, and Stellenbosch University in South Africa have involved collaborative research, and leadership of the Melbourne Geology of Gold course since 1995 and similar courses in South Africa. Recent collaborative topics have included Victorian gold placers of Victoria, Siberia and Nome Alaska, structural geology of gold deposits and provinces. Neil is Editor of the Australian Ore Deposit monograph, regularly publishes in scientific journals, and has written and edited several books on geoscience, cross-country navigation, and rogaining.
Workshop 2
Pressure-temperature constraints, phase equilibira and open system modelling of geological processes
Matt Mayne (SU)
Sun 28 June 2020
1 day
The full-day workshop is aimed at a postgraduate level and only requires a basic knowledge of mineralogy and geochemistry. The workshop will be of interest to anyone wanting to use phase equilibrium modelling to supplement geochemical studies in igneous or metamorphic petrology. In this workshop attendants will learn: 1) initial handling of geochemical data; 2) understanding thermodynamic data and how gibbs free energy minimisation can be used to predict stable phase assemblages; 3) performing phase equilibira modelling to approximate Pressure and Temperature constraints in natural systems; 4)Using Rcrust to perform open system modelling including melt extraction, fractional crystallisation and prograde dehydration (https://doi.org/10.1144/SP491-2018-85).
Fieldtrip 1
Geology of the Malmesbury Group and Cape Granite Suite of the Pan-African Saldania Belt
Alex Kisters, Gary Stevens, John Clemens (SU)
Fri 26 June - Sun 28 June 2020
3 days
A field trip into the geology of the Pan-African basement rocks of the Western Cape – the Saldania Belt - highlighting recent findings into the geology and stratigraphy of the Malmesbury Group and petrogenesis of the Cape Granite Suite. The excursion will start and end in Stellenbosch and is planned as a round trip from the Cape Peninsula and up the West Coast to the Langebaan lagoon, traversing the Swartland and Boland regions and back to Stellenbosch. Amongst other aspects, the trip showcases granite structures and textures of the ca. 540 Ma S-type Peninsula Pluton that illustrate the magmatic assembly and internal deformation of the pluton. It examines at the famous Sea Point Contact and heads further up the West Coast illustrating soft-sedimentation structures, volcanic intercalations and deformational styles of the upper parts of the Malmesbury Group. S-type ignimbrites that are coeval with the Peninsula Pluton will be visited around the Langebaan lagoon, Saldanha and Trekoskraal. Coastal granite outcrops around Trekoskraal and Cape Columbine illustrate intrusive relationships and the effects of the central Colenso Fault. Outcrops in the large and composite S-type Darling batholith document the syntectonic emplacement of granites during regional shearing, while high-grade metamorphic xenoliths provide a glimpse into the deeper structure of the Saldania Belt and possibly the source rocks to some phases of the batholith. The trip concludes with outcrops of Malmesbury Group rocks between Piketberg and Riebeck Kasteel which expose windows into lower structural levels of the belt.
Max. 25
The trip involves short hikes and/or walks along coastal outcrops, road cuts and quarries. Weatherproof gear is highly recommended in the Cape winter. Accommodation is in country hotels. Lunch will be provided, dinner is at own expense.

Workshop 3
Half-day workshop on South African Stratigraphy
Cameron Penn-Clarke (SACS)
Tues 30 June 2020
Half day
An introduction and history of SACS; An introduction to the South African Stratigraphic Code; Reporting stratigraphy, the SACS-way (Standardised descriptions for lithostratigraphic units, lithodemic units, biostratigraphic units, recent unconsolidated deposits); Advances in South African stratigraphy: Where we are at present; Where are the “holes” in South African Stratigraphy and what can be done; What is the future of SACS and how can we increase its visibility and membership
Free of charge; anyone interested in stratigraphy and stratigraphy of South Africa is welcome to attend; refreshments will be served.
Workshop 5
SIMS workshop
Sarah Glynn
Tues 30 June 2020
Half day
This workshop will provide attendees with a brief overview on the basics of SIMS instrumentation as well as its applications within the Earth Sciences (and may therefore also be of interest to those in palaeo-sciences), but anyone with a general interest is welcome to take part. The SIMS basics component will cover what SIMS is, and how it is uniquely equipped to perform certain analyses; also touched on will be how SIMS can be applied: i.e. trace element determinations, isotopic studies, geochronology in addition to its depth profiling and ion imaging capabilities. An additional component of this will also be to introduce the virtual SIMS laboratory and how users can gain access.
Fieldtrip 2

Workshop 6
3D geological modelling
Ian Basson (TECT)
Thurs 2 - Fri 3 July 2020
2 days
3D geomodelling is the applied science of creating computerized representations of portions of the Earth's crust, based on geophysical and geological data.  A geomodel, which is the numerical equivalent of a three-dimensional geological map, complemented by a suite of physical quantities within the volume of interest, represents the “Shared Earth Model”, developed in the 1990’s.  Recent trends are away from software packages that have unforgiving data import routines, employ explicit or section-based modelling and which incorporate limited data sets or types.  The trend is now towards software packages that have flexible import routines; comprehensive data checking and cleaning tools; rapid, dynamic, implicit modelling of surfaces, volumes and shells; integration of large numbers of disparate data sets and 3D querying of spatial data to determine trends and patterns. These packages typically employ an easy, workflow-driven approach. The course is not specific to any modelling package but rather presents underlying data and techniques employed in creating usable geometries for downstream workflows.  The course will be of particular relevance to those who are: a) Unfamiliar with 3D geomodelling;  2) Considering specializing in this field; 3) Seeking to better understand and interrogate 3D geomodels; 4) Professionals or companies that are considering changing software packages and 5) Geoscientists that want to understand the relatively recent move towards rules-based implicit modelling.
