Rheological structure of plate boundary strike-slip faults »

2pm 30 May 2019

The boundaries of tectonic plates cover ~15% of Earth’s surface and constitute areas of significant natural hazards, including earthquakes. As ~40% of Earth’s population lives along plate boundaries, it is critical to understand what aspects of lithospheric deformation control earthquakes in interplate settings....

Challenges with identifying crustal assimilants at an intermediate-composition arc volcano »

1.30pm 24 May 2019

A central objective of petrogenetic studies is to determine the proportions of crystallised magma to assimilated country-rock. In assimilation-fractional crystallisation (AFC) calculations, this is represented by the “r-value”. To calculate assimilation/crystallisation proportions, it is necessary to know the...

The Significance of Serpentine »

2pm 23 May 2019

The mineral serpentine is the result of low-grade metamorphic reactions between ultramafic rocks and water. Given that the rocky envelopes of the terrestrial planets and moons are mainly ultramafic, and water is a common molecule, especially on the outside of these bodies, serpentine assumes a position of...

Glacial sea ice variability in the Norwegian Sea during abrupt climate changes 32–40 ka »

1pm 22 May 2019

The last glacial period was marked by pronounced millennial-scale climate changes that were first documented in Greenland ice core records and thereafter in numerous ocean and climate records from around the world. This so-called Dansgaard-Oeschger (D-O) climate variability comprises one of the most pronounced and...

The evolution of the Great Barrier Reef: a decade of progress & future directions. »

2pm 16 May 2019

Predicting how the Great Barrier Reef (GBR) will respond in the face of future global climate changes is both poorly constrained and controversial. This relates to our incomplete understanding of how reef systems respond to environmental changes but also the lack of baseline data — particularly on centennial to...

Towards a pretreatment for radiocarbon dating tooth enamel »

1pm 15 May 2019

Radiocarbon dating bone that is more than a few thousand years old in tropical and arid regions of Australia and South East Asia is hampered by the rapid degradation of the protein normally targeted for dating. In the best-case scenarios, a few bones with a little protein can be found when large numbers of bones...
