Scissor detachments and oroclinal warps, Grampians / Gariwerd, western Victoria – a case study of semi-ductile cover sequence
deformation driven by brittle trans-tensional bedrock deformation - crucial new understanding that helped unlock the Stavely Arc puzzle
Ross Cayley is a structural geologist, field-mapping specialist and geological systems analyst who joined the Geological Survey of Victoria in 1990. Ross has nearly 3 decades in experience in field mapping, collaborative geological and geophysical data acquisition, geological interpretation and integration of geological and geophysical datasets across SE Australia. The regional- to continental-scale geological models developed include the ‘Selwyn Block’ model (2002) the ‘Vandieland’ model (2010), the ‘thick-skinned’ LFB deformation model (2011), the ‘Stavely Arc’ model (2018), and the ‘Lachlan Orocline’ model (2013-ongoing).
Ross will present on the analytical and conceptual workflows that lead to these models, using a recent research project in western Victoria as an example: integration of geological mapping, geophysics and whole-of-system thinking that helped unlock the mineral potential of the Stavely Arc, delivering unexpectedly intriguing insights into the complex geological evolution of the overlying Grampians Ranges en-route. The future of geoscience in Australia is integration and systems-analysis; of geology, geophysics, modelling, tectonics, geodynamics. This talk points towards how this exciting future might look.
