Wed 1st April 12 – 1 pm Rm 312.222 One of the more difficult challenges involved in the disposal of radioactive waste in deep geological repositories is the very long time frames required by safety assessments. In the case of one Canadian project – Ontario Power Generation’s Deep Geological Repository (OPG DGR) project for the management of low […]

Wed 25th March 12 – 1 pm, Rm 312.222 Abstract The IOCG deposit group includes temporally and spatially associated hydrothermal and magmatic end-members which are associated with magmas belonging to the shoshonitic series, e.g., Olympic Dam, Missouri, El Laco, Great Bear Magmatic Zone.  They have been interpreted to have formed from similar parental silicate magmas along contrasting petrogenetic […]

The structure of the Neoarchean Yilgarn Craton is dominated by craton-scale high-strain zones, mostly associated with highly-deformed elongate granitic bodies and transposed greenstone belts. These shear zones developed during widespread and prolonged magmatic activity that led to a nearly complete reworking of the felsic continental crust. Recent structural works show that some of these shear […]

Ice Sheet Collapse, Sea Level Rise and Coastal Response The response of polar ice sheets to modest increases in global temperature and the rate of future sea-level rise remains highly uncertain. One way of addressing these uncertainties is to examine past interglacials, which contain records of both changes in ice sheet mass balance and associated […]

Fri 20th  February  12 – 1 pm  Rm 312.222 Mineralised Cu-Mo-Au porphyries were discovered in belts of Cambrian andesite in the Stavely region of western Victoria in the early 1990s.  Deep weathering complicated early geochemical exploration and only a small number of diamond holes to several hundred metres depth were drilled.  These encountered sub-economic grades […]

Collecting and Melting: Meteorites from the Nullarbor and Icy Planets Andrew Langendam, School of Earth, Atmosphere and Environment Wed 4th February 12 – 1 pm Rm 312.222 For the past seven years, the Monash Meteorites Group has been conducting field expeditions to the Eastern Nullarbor in search of meteorites. Our search technique, a non-traditional one, […]

Dr Victor Manuel Calo Associate Professor in Applied Mathematics & Computational Science & Earth Science & Engineering, Co-Director of SRI-Center for Numerical Porous Media 10-11 am Wednesday 18 February, Building 210 Room 104 (Elizabeth Jolley Case Study Room) In this presentation, we describe two important applications in Computational Geoscience. 1. Multiscale Model Reduction for Flows in Heterogeneous […]

A/Prof. Craig O’Neill ARC Centre of Excellence in Core to Crust Fluid Systems Macquarie University, Sydney 9 am Thursday 12 February — Building 210 Room 104—Elizabeth Jolley Case Study Room Whether or not the Earth has transitioned from an earlier archaic mode of tectonics, into modern plate tectonics, is one of the fundamental questions in […]

Wed 3rd December 12 – 1 pm Rm 312.222 Stephen Gallagher Department of Earth and Atmospheric Sciences, Univer International Ocean Discovery Program Expedition 356, August-September 2015 Reefs, Oceans, and Climate: A 5 million year history of the Indonesian Throughflow, Australian monsoon, and subsidence on the Northwest Shelf of Australia Stephen J Gallagher, Craig Fulthorpe and Kara Bogus Abstract […]

Wed 26th November 12 – 1 pm Rm 312.222 Steve Micklethwaite Centre for Exploration Targetting, UWA The Duration and Dynamics of Orogenic Deposit Formation Abstract Here I briefly review the physical hydrogeology of orogenic-type gold deposits and their linkages to self-organizing phenomena, such as earthquake-aftershock sequences, seismic swarms and fluid pressure driven failure. Building on these […]
