On the Age of Fish Canyon Sanidine
On the Age of Fish Canyon Sanidine
The story of the age of Fish Canyon Sanidine, a key reference material for Ar-Ar geochronology, exemplifies how geochronological methods have evolved over the past couple of decades...

Standardising high-precision U-Pb geochronology
Standardising high-precision U-Pb geochronology
Where do U-Pb dates come from? How do we know at what level of uncertainty can one date from laboratory X can be compared to Laboratory Y? What is the accuracy of the U-Pb system and how can it be used to better calibrate other chronometers?

The GTSnext Training Network
The GTSnext Training Network
GTSnext was a Marie Curie Initial Training Network that was in operation from 2008 to 2012. It supported twelve early stage researchers (PhD and Post-doctoral level) and involved training in and application of integrated geochronological methods (radio-isotopic dating, cyclostratigraphy, paleomagnetics) to the calibration of the geolgical timescale.

Geologists rely heavily on multiple radio-isotopic dating methods to understand the processes that control the formation of mountain belts such as the Himalaya pictured here... Blog post to come!
Sequencing the Neoproterozoic
Sequencing the Neoproterozoic
Telling time in Precambrian is heavily reliant upon radio-isotopic dating methods to provide absolute ages for key sedimentary sections, but also to test other stratigraphic correlation models. Blog post to come!
