Satellite Selfies Australia from Space Education Poster

<div>The A1 poster incorporates 4 images of Australia taken from space by Earth observing satellites. The accompanying text briefly introduces sensors and the bands within the electromagnetic spectrum. The images include examples of both true and false colour and the diverse range of applications of satellite images such as tracking visible changes to the Earth’s surface like crop growth, bushfires, coastal changes and floods. Scientists, land and emergency managers use satellite images to analyse vegetation, surface water or human activities as well as evaluate natural hazards.</div>

The Delamerian Orogen – An overview of the resistivity structure across scales

Here we present 3D and 2D resistivity models of the lithosphere beneath an area of southeast Australia, derived from Australian Lithospheric Architecture Magnetotelluric Project (AusLAMP) data and a subsequent infill broadband MT transect collected in October 2020. The Flinders Ranges, South Australia, is a zone that has been weakened by multiple Precambrian rift cycles related to the breakup of Rodinia, which may have led to the utilisation of this lithosphere for the focussing of fluid alteration causing high conductivities at crust and upper mantle depths in this region, as imaged in the AusLAMP 3D resistivity models. The northwestern end of a 100 km MT transect traverses this region and its 1.5 km MT site spacing resolves high conductivity pathways that broadly correlate with previously identified mineral prospects. These pathways straddle the resistive granodiorite rocks of the Anabama pluton, known to host porphyry-style mineralisation. To the southeast, the transect images the onlapping Mesozoic Murra Abstract presented at Australasian Exploration Geoscience Conference (AEGC), 15-17 September 2021, Brisbane, Australia
