Wed 18th August 2021 @ 12:00 nn in 312.222 and online via Webex (meeting #: 1849 67 0138 and password: ZDtDZNaZ374) Abstract: The limited preservation of ancient crustal material poses a challenge for understanding the composition of Earth’s early crust. As a result of poor preservation and near-ubiquitous overprinting by later geological events, deciphering the early evolution of our […]

Wed 17th March 2021 @ 12:00 nn in 312.222 and online via Webex (meeting #: 184 504 2665 and password: NZtPPEpY842) Abstract: The diverse clan of ore deposits classed iron oxide copper-gold (IOCG) systems are among the most heavily studied type of deposit, yet, there is little consensus on the fluid sources, mechanisms and timescales by which they form. This […]

Wed 11th November 2020 @ 9:00 am on Webex (Meeting #: 176 783 7775, password: J2XrX8PRnP7) Abstract: Quartz cementation is a major factor in the evolution of bulk properties in the common sandstone types of conventional reservoirs (quartzo-feldspathic sandstones). Is the same true of unconventional reservoirs? High-resolution compositional imaging such as EDS elemental mapping and cathodoluminescence imaging by […]

Wed 4th November 2020 @ 12:00 nn at 312.222 Abstract: Exceptionally preserved fossils from the Late Devonian Gogo Formation, in the Canning Basin, Western Australia have provided the earliest record of 3D muscle preservation. The use of synchrotron and neutron micro tomography reveals the presence organs (eye, stomach, liver and guts) and provides the first evidence for the internal […]

Wed 28th October 2020 @ 12:00 nn at 312.222 Abstract: Integrating monazite into existing pressure–temperature frameworks is an essential step towards fully realising the significant potential of this mineral in petrochronology. To further this endeavour, we present a predictive and readily adaptable equilibrium thermodynamic calculation framework involving solid solution for monazite, apatite, allanite, xenotime and Y+LREE+P+F+Th-bearing silicate melt. […]

Wed 21st October 2020 @ 12:00 nn at 312.222 and via Webex (Meeting number (access code): 170 169 8534, Meeting password: p4nFqGiTH64) Abstract: The Proterozoic (~1.43 Ga) Velkerri Formation (Beetaloo Basin, Northern Territory) hosts one of the world’s oldest petroleum systems, sourced and reservoir within organic-rich black shale deposited in a marine setting. A comprehensive characterisation of the […]

Wed 26th August @ 12:00 nn via Webex (WATCH RECORDING HERE) Abstract: The Earth’s mantle is currently divided into the African and Pacific domains, separated by the circum-Pacific subduction girdle and each domain features a large low shear-wave velocity provinces (LLSVPs) in the lower mantle. However, it remains controversial as to whether the LLSVPs have been […]

Wed 25th March @ 6:30 pm, Tim Winton Lecture theatre, Building 213, Level 1 Abstract: Dr Erickson will talk about the discovery of the oldest asteroid strike on Earth, called Yarrabubba, which is located on the road to Meekatharra in Western Australia. The impact site was discovered nearly 20 years ago, however, the age of impact was […]

Wed 18th March @ noon, Rm 312.222 Abstract: Ore forming processes involve the redistribution of heat, mass and momentum by a wide range of processes operating at different time and length scales. The fastest process at any given length scale tends to be the dominant control. Applying this principle to the array of physical processes that […]
