ARGA specialist group webinar with joint ARGA Symposium student award winner, Kathleen Vowles (PhD candidate, JCU).
One of the seminal U-Pb detrital zircon provenance studies on the geological history, sedimentology, and age of the bedrock geology of eastern Australia was based on modern beach samples collected from Fraser Island (K`gari) (southern Queensland) and southward (to south Victoria). However, the provenance of coastal sediments north of Fraser Island (K`gari) in eastern Australia remains to be discovered and is the focus of this study. Beach sediments were systematically sampled from 23 locations across southern, central, and northern Queensland, as well as Thursday Island, the north tip of Cape York, and then dated via U-Pb laser-ablation inductively coupled mass spectrometry. This research has highlighted how beach sediment can provide insights into the tectonic evolution of a region, which has been an untapped resource for tectonic reconstructions.
Kathleen Vowles is a current PhD student, tutor, and ambassador at James Cook University, exploring the wonders of dunes and beach sediment in northeastern Australia. Kathleen's research covers a vast area of Queensland from the tip of Cape York in the north to Bribie Island in the south. Kathleen's aim is to determine if you could use a single grain of sand to tell a story about plate tectonics. Kathleen hails from South Africa, where she pursued a Masters in Geoscience exploring Elephant, White Rhino, and Warthog wallowing ethology as well as faunal occurrence at naturally forming waterholes in Shamwari Private Game Reserve.
