b'Geophysics in the SurveysNewsMineral Resources Tasmania: Geophysical activities in 2019(a) (b)Figure 1.(a) Geoscience Australia geophysicist Darren Kyi prepares the ground for electrode placement at an AusLAMP MT site near the northern end of King Island, auguring well for insights into lithospheric conductivity. (b) Long-period MT recording equipment approaching readiness for barricading against livestock depredations, southern King Island.Geophysical activities at Mineral Resources Tasmania (MRT) continue to be broad ranging and the Tasmanian component of the AusLAMP continental magnetotelluric coverage is of national significance. MRT staff assisted Darren Kyi and Tanya Fomin from Geoscience Australia in deploying the final Tasmanian stations on King Island in June 2019 (Figure1a and b). However the lions share of AusLAMP in Tasmania has been conducted as part of Thomas Ostersens PhD research at the University of Tasmania. Tom is being supervised by Anya Reading and Matt Cracknell and supported by GA and MRT with co-supervision and assistance from Graham Heinson, Stephan Thiel and Kate Robertson at the University of Adelaide and the Geological Survey of South Australia. Full results will be released following the imminent submission of Toms thesis, however a tantalising taster is given in Figure 2 (9.4 km depth slice). An association between conductive zones in the upper crust and highly serpentinised ultramafic slices previously interpreted in 3D modelling on magnetic and geological grounds is among the many intriguing features revealed.Mineral Resources Tasmanias suite of 3D geological models driven by potential field inversion and structural modelling continues to be expanded and refined,Figure 2.Conductivity depth slice, courtesy of Tom Ostersen (PhD thesis in prep.).AUGUST 2019 PREVIEW 22'
