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 –...

The 2018 National Seismic Hazard Assessment for Australia »

2pm 9 August 2018

Since the publication of the Global Seismic Hazard Assessment Project (GSHAP) hazard map in 1999, Australia has stood out as a region of high earthquake hazard among its stable continental region (SCR) peers. But does this assessment reflect our current understanding of earthquake processes and seismic hazard in...

Seismic velocity and anisotropy of the inner core »

5pm 7 August 2018

Since the discovery of the inner core via observational seismology in 1936, the nature of its internal structure and dynamics has been at the forefront of deep Earth research. Increasingly complex models are being developed to accommodate both small and large scale features observed in multiple seismic datasets....

Exploring barnacle exoskeleton formation »

2pm 2 August 2018

Barnacles are ancient arthropods that, as adults, consist of a soft organism surrounded by a hard, often calcitic, outer shell that the organism produces for protection. While research has been done into the glue-like cement that...
