Pre-Conference Field Trips

Redefining Archean terrane boundaries in the southwest Yilgarn Craton

Leaders: Raphael Quentin de Gromard (GSWA), Cat Gill (UWA/GSWA)


Dates: Friday 23 June to Sunday 25 June 2023 (3 days including two nights at Victoria Hotel or Freemasons Hotel, Toodyay)

Summary:The far west and southwest Yilgarn represents perhaps the most geodynamically complex portion of the Yilgarn Craton and has recently become one of Western Australia’s prime new exploration frontiers. Recent work by the Geological Survey of Western Australia has proposed that the boundary between the c. 3010–2635 Ma Youanmi Terrane and the c. 2705–2610 Ma South West Terrane of the Archean Yilgarn Craton be relocated approximately 200 km to the southwest along the southwestern deformation front of the newly defined c. 2665–2635 Ma Corrigin Tectonic Zone (CTZ). This excursion will visit key exposures of tectonized greenstones and high-grade gneisses in the well-exposed Toodyay-Northam area (about 100 km from Perth). The field sites will be an ideal platform from which to discuss the geological history of the southwest Yilgarn, the rationale for location of the terrane boundary and implications for Au–Cu, Ni–PGE, Ti–V, VMS, and Fe mineral systems.

Cost Per Person: $995 inc. GST

Tickets Include:

  • Bus transport from PCEC 23/06, all touring over the 3 days and drop-off at PCEC on 25/06
  • 2 nights accommodation at Victoria Hotel, Toodyay
    • Self-contained unit with ensuite and kitchenette
  • Food package over the 3 days, including dinner (Friday and Saturday night), continental breakfast (Saturday and Sunday) and packed lunch (Saturday)

Field Trip Update as at 1 June 2023: Accommodation availability at the Victoria Hotel, Toodyay is full, however, rooms are available at the Freemasons Hotel (across the road). Room configurations include either a double or single bed with shared bathroom and are based on availability at the time of booking. To enquire about a booking, please email

Wadjemup / Rottnest Island: Coastal environmental change and Quokkas

Leaders: Dr Moyra Wilson (UWA)


Dates: Monday 26 June 2023

Though some 18 km offshore at the present day, during previous glacial lowstands Wadjemup (Rottnest Island) was joined to the mainland. Evidence of fluctuating sea-levels and environmental change is preserved both in the oral histories of the Whadjuk Noongar people but also the rocks and landforms of the island. Wadjemup offers excellent opportunity to explore classic carbonate aeolianites, coral reef, lacustrine and lagoonal deposits and marine features that are a conspicuous feature of the Pleistocene Tamala Limestone and associated units that outcrop over some 1000 km of WA’s coastline. This trip will also facilitate broader discussions of approaches to palaeo-sea-level reconstructions, climate change and the coastal dynamics of WA’s younger geological evolution.

Cost Per Person: $212 inc. GST

Tickets Include:
• Ferry to and back from Fremantle B-shed to Rottnest
• On island transport – bus transport and support vehicle from the Thompson Bay Settlement to Salmon Bay, West End and Pink Lake (afternoon walk back from Pink via Lakes Walk (4 km: Wadjemup Bidi: Gabbi Karniny Bidi) on gravel tracks)
• Picnic lunch and snacks (please bring a keeper cup if you wish to purchase hot drinks on your way through the settlement in the morning). Please advise of dietary requirements.

Tickets do not include:
• Travel from and to Perth City Centre to Fremantle B-shed. Participants will need to be at Fremantle B-shed for 7.10 am for a 7.30 am departure (Rottnest Express ferry leaves at 7.30 am, boarding is earlier). From the city centre (Perth Underground) Transperth trains run to Fremantle Train Station from which it is a ~3 minute walk to Fremantle B-shed (exiting station, turn right and right again over rail crossing, then keep leftish (SW) across carparks to B-shed at Fremantle habour). – Single adult train tickets should be around $3 to $5 from the city centre. Shared UBERs, taxi or buses are another way to get to Fremantle B-shed.

• Drinks, please bring refillable water bottles and keeper cup to minimise single-use items.
