Continental growth and evolution in eastern Australia: Insights from seismology and geodynamics
30th March @ 12:45 pm - 1:45 pm
Phanerozoic eastern Australia formed through a process of subduction accretion during retreat of the proto-Pacific plate along the East Gondwana margin. Despite being well studied, the basic building blocks of the orogens which span this region, and their mode of assembly, is still not well understood. In this talk, I will present the latest passive seismic imaging results from the WOMBAT transportable seismic array in eastern Australia, and discuss their implications. Geodynamic modelling results, constrained by the new seismic imaging, will be used to shed light on the widespread occurrence of Cenozoic intraplate volcanism inboard of the east coast.
