Wed 7th December 2022 @ 12:00 nn, 312.222 and online via Webex (meeting #: 2654 563 1797 and password: 6VwJRMFiM95) Abstract: Mineral exploration is challenging in much of Australia with mineral resource potential frequently concealed beneath regolith. Heavy minerals, such as zircon, spinels, and cassiterite, are widely used by mineral explorers and can provide information on geochemistry, alteration and […]

Ziyi Zhu (Australian National University) on “Unravelling the evolution of continents using detrital zircons from modern rivers”
Wed 30th November 2022 @ 12:00 nn, 312.222 and online via Webex (meeting #: 2655 735 2039 and password: rZQ77e7XU8W) Abstract: Detrital zircons collected from Earth`s modern rivers provide a representative sample to study the evolution of the continental crust on a global scale. This is because most of the eroded material in modern rivers has experienced long-time sediment-sediment […]

Damaris Butters (U. Bristol) on “Transcrustal, volatile-charged silicic melts revealed by zircon-hosted melt inclusions”
Wed 23rd November 2022 @ 12:00 nn, 312.222 and online via Webex (meeting #: 2652 439 4990 and password: JGf36T2PPgx) Abstract: The volatile contents of silicic crustal magmas inform models for volcanism, degassing behaviour, and hydrothermal ore formation. Volatile saturation pressures of phenocryst-hosted melt inclusions are generally restricted to late-stage, shallow magmas that have typically undergone substantial, ascent-driven degassing of […]

Michael Brown (U. Maryland) on: “The emergence and evolution of plate tectonics on Earth: a petrological perspective”
Wed 2nd November 2022 @ 12:00 nn, 312.222 and online via Webex (meeting #: 2650 711 1383 and password: 2dpBV3Xe2T3) Abstract: Based on the crustal record of magmatism and metamorphism, Earth likely evolved from a single-lid (sluggish or squishy) to a mobile-lid tectonic mode during the late-Archean–early-Proterozoic. Time-constrained data show a strong temporal clustering of metamorphism associated with periods […]

Amy Elson (Curtin) on: “Descent from the Hyperthermals: Persistent Organic-Matter Rich Lakes in the Eocene”
Wed 22nd June 2022 @ 12:00 nn, 312.222 and online via Webex (meeting #: 2654 445 7342 and password: JYiaHrxg423) Abstract: In this study, continental paleoclimate from the early Cenozoic is reconstructed, when the Earth’s surface experienced a long-term warming trend punctuated by a series of short-lived global warming (hyperthermal) events that culminated in an extended interval of elevated CO2 and […]

Andrew Langendam (ANSTO) on: “Earth and Environmental Science at the Australian Synchrotron”
Wed 18th May 2022 @ 12:00 nn, online via Webex (meeting #: 2654 682 4419 and password: 63YkRZ2Agf3) Abstract: Techniques offered at the Australian Synchrotron allow for the determination of the elements and phases present in a mineral assemblage, and time resolved structural characterisation. This talk is aimed at researchers that have used the Australian Synchrotron and those interested […]

Stuart Phinn (U. Queensland) on: “Opportunities for working across knowledge systems with earth-observation: working with inter-planetary and indigenous approaches?”
Tues 22nd March 2022 @ 12:00 nn in 207.222 and online via Webex (meeting #: 2652 672 5983 and password: wxC9n3ngrx8) Abstract: Is satellite based, earth- or inter-planetary observations for measuring, monitoring and understanding the earth and other planets, not accurate or use-able unless linked to some sort of “ground knowledge”? This question and how to address it beyond […]

Robert Seggie (Curtin University) on: “Dinoturbation of the Broome Sandstone and a proposed new lithofacies and lithofacies association – SandStone Deformed Dinoturbation (SSDD).”
Wed 29th September 2021 @ 12:00 nn in 312.222 and online via Webex (meeting #: 2518 636 1317 and password: wmSWYpYU324) Abstract: The presence of dinosaur footprints in the Early Cretaceous aged Broome Sandstone of northwestern Western Australia has been known for decades. Previous work has focussed on the discovery of sites, identification of species from the footprints and […]

Luc Doucet (Curtin University) on: “Trash to treasure: from dead living things to deep diamonds”
Wed 15th September 2021 @ 12:00 nn in 312.222 and online via Webex (meeting #: 1704 36 9616 and password: yD3iDJe4cK5) Abstract: Rare oceanic diamonds are believed to have a mantle transition zone origin like super-deep continental diamonds. However, oceanic diamonds have a homogeneous and organic-like light carbon isotope signature (δ13C − 28 to − 20‰) instead of the extremely variable organic […]

Robert Howie (Curtin University) on: “Classrooms in the Cloud”
Wed 1st September 2021 @ 12:00 nn in 312.222 and online via Webex (meeting #: 1708 27 0571 and password: q5K2VTQKrV7) Abstract: As a first-time teacher, Robert went a bit off the beaten track in the delivery of AERO3000 Space Systems Design. In this talk Robert will give a brief overview of the techniques used and lessons learned delivering this […]
