The meetings are energetic and open, with problems, questions and suggestions welcomed in the spirit of learning from and helping each other to move work forward.

We often have ‘curiosities’ as an inspiration for discussion.

A curiosity can be a scientific sample, piece of equipment, antique, invention, tool or artwork that relates to the theme of the main presentations.

The performance characteristics of the IPD are described, together with some examples of its application to zircon dating.

Luminescence dating refers to a group of methods of determining how long ago mineral grains were last exposed to sunlight or sufficient heating.

The lab is a space to explore common ground in working practices and to generate new knowledge through talking and making together.

"Optical dating" typically refers to OSL and IRSL, but not TL.

All sediments and soils contain trace amounts of radioactive isotopes of elements such as potassium, uranium, thorium, and rubidium.

These slowly decay over time and the ionizing radiation they produce is absorbed by mineral grains in the sediments such as quartz and potassium feldspar.

The radiation causes charge to remain within the grains in structurally unstable "electron traps".

It is useful to geologists and archaeologists who want to know when such an event occurred.
