Wed 26th September @ 12:00 pm, Rm 312.222  The Bight Basin on the southern margin of Australia is nearly 2000 km wide from west to east and overlies a number of different basement terranes including the Albany-Fraser Orogen in the west and the Gawler Craton in the east. Terrane boundaries in the onshore portion of the southern […]

Curtin Applied Geology Seminar Wed 21st September @ 12 pm Rm 312.222 Giada Iacono Marziono Institut des Sciences de la Terre d’Orléans Assimilation of sulfate and carbonaceous rocks: experimental study, thermodynamic modeling and application to the Noril’sk-Talnakh region.   Most of the intrusions in the Noril’sk-Talnakh region (Siberia) are hosted in thick sedimentary sequences, including abundant evaporitic and terrigenous sedimentary rocks. Only […]

Wed 7th September @ 12:00 pm Rm 312.222  Daniel Viete (John Hopkins University) Investigating the origins of rhythmic major-element zoning in HP/LT garnets from worldwide subduction mélanges Rhythmic major-element zoning has been documented in garnets from high pressure/low temperature (HP/LT) lenses within a number of worldwide subduction mélanges (e.g. California, Chinese Tianshan, Cuba, Greek Cyclades, Guatemala, Japan, Venezuela). The origin of these features […]

Wed 10th August @ 12:45 pm, Rm 312.222  Abstract Large Igneous Provinces (LIPs) represent large volume (>0.1 Mkm3; frequently above >1 M km3), mainly mafic (-ultramafic) magmatic events of intraplate affinity, that occur in both continental and oceanic settings, and are typically of short duration (<5 m.y.) or consist of multiple short pulses over a maximum of […]

Wed 3rd August @ 12 pm, Rm 312.222  Garnet has become a key target for geochronological studies. Technical and analytical advances in the past two decades have made garnet geochronology a powerful approach to constrain the evolution of metamorphic rocks. Not only may precise metamorphic dates be obtained from multi-point isochron diagrams but also the tempo of […]

Wed 20th July @ 12 pm, Rm 312.222  Abstract: We are studying the surfaces of other planets at increasingly high resolution, effectively placing ourselves there as researchers. This necessitates a good understanding of processes and landforms we might see, studies of which are often much easier to perform on Earth, where we can walk around on the […]

Mon 18th July @ 12 pm, Rm 312.222 The global climatic phenomenon known as Snowball Earth is arguably the most exciting and challenging discovery in geology in the last 35 years. It is inherently multidisciplinary: its recognition came from geology, its origin and predictive nature from climate dynamics, its verification from geochemistry and geochronology, and its legacy is geobiological.

Wed 1st June @ 12 pm, Rm 312.222 Auriferous sulphides, most notably pyrite (FeS2) and arsenopyrite (FeAsS), are some of the most important strategic minerals on Earth because they host gold in many of the world’s major gold deposits. To increase our understanding of mineralisation processes, we combined atom probe microscopy, high-resolution secondary ion mass spectrometry (NanoSIMS), […]

Wed 4th May @ 12 pm, Rm 312.222 The sharp fall in oil prices since mid-2014 has been driven by a number of factors, however empirical estimates indicate that supply (much more than demand) has accounted for the lion’s share of the latest plunge.   The increase in supply has come from a boom in North American […]
