Dedalus Workshop - Geoff Vasil (U. Sydney) »

2pm 24 August 2018

Join us for a very special Seminar and Workshop exploring Dedalus - A flexible framework for spectrally solving differential equations. Dedalus is used for fluid dynamics research, but can be applied to any initial-value, boundary-value, and eigenvalue problems involving nearly arbitrary equations sets.  1...

The birth, growth and ageing of the Kaapvaal subcratonic mantle »

2pm 23 August 2018

The origin of the peridotites that form cratonic mantle roots is central in understanding the history and survival of Earth's oldest continents. A major issue over the last decades was the depth of melting that generated the nuclei of cratons. A new evaluation of element partitioning between minerals and melt based...

Millennial-scale variability in south-east Australian hydroclimate between 30,000 and 10,000 years ago »

1pm 22 August 2018

Global climate variability during the late Quaternary is commonly investigated within the framework of the ‘bipolar seesaw’ pattern of asynchronous temperature variations in the northern and southern polar latitudes. The terrestrial hydrological response to this pattern in south-eastern Australia is not fully...

Potentials and problems of ESR thermochronometry »

5pm 21 August 2018

Low temperature thermochronometry gives insights into the interaction between surface processes and underlying tectonics. Electron spin resonance (ESR) thermochronometry works by determining the timing and rate at which electrons are trapped and thermally released in quartz in response to in situ ionizing...

Ultrahigh-pressure synthesis and applications of transparent nano-polycrystalline minerals »

2pm 20 August 2018

Since our first report of successful synthesis of nano-polycrystalline diamond (NPD = Hime-diamond; Irifune et al., Nature 2003), efforts have been made to synthesize polycrystalline aggregates of various high-pressure phases under ultra-high (>10 GPa) pressure and high temperature in Kawai-type multianvil...

Faults and fluid-rock reaction: controls on the massive Carlin-type gold deposits of Nevada »

2pm 16 August 2018

The Carlin-type gold deposits of Nevada represent one of the greatest gold concentrations on Earth. The deposits are hosted within limestones and dolomites of the Great Basin in Nevada. While the deposits are huge, and formed from large volumes of fluids, those fluids have left only cryptic signatures of their...

Top and Bottoms of Porphyry Copper Deposits Revisited: From Source Magmas to the Lithocap Alteration Zones »

2pm 13 August 2018

SEG Lecturer Series: Thayer Lindsley Visiting Lecturer Forty-five years after Dick Sillitoe (1973) published his famous paper titled “Tops and Bottoms of Porphyry Copper Deposits,” the science of geology has improved our understanding based on fluid inclusion, geochronology, and petrology –...
