The Earth-Moon system is thought to have formed in a volatile-poor environment relative to the outer Solar System. Despite this, measurable quantities of volatile elements have been reported in lunar samples. These volatiles do not necessarily represent primordial (i.e., original) … Continue reading
Zircons (tiny crystals of ZrSiO4) are found in many rocks and are widely used to measure the age of rocks. This is usually done by looking at uranium-lead (U-Pb) and lead-lead (Pb-Pb) ages, both of which rely on radioactive decay … Continue reading

Q: How do we date the sequence and timing of events in the early solar system? A: Using radiometric dating. Most of you have probably heard of carbon dating, which relies of the radioactive decay of one form of carbon, … Continue reading

Comets may have brought the water that gave rise to the oceans, the atmosphere, and potentially life to Earth. Continue reading
A waypoint in the journey from interstellar space to atmosphere. Article written by Jamie Gilmour. Minute quantities of xenon and iodine trapped in nanometre size grains of diamond found in meteorites tell a story about how the elements that make … Continue reading

As something new on our blog, we thought we’d start updating readers when new papers or conference abstracts from the group are published. As many papers are published open access, the majority of our papers should be available online to … Continue reading

Austin Power’s nemesis Dr Evil was always up to no good, punching holes in ‘the protective layer around the Earth, which we scientists call the “Ozone Layer”’ with his ‘sophisticated heat beam which we called a “laser”’. Of course we … Continue reading
Well we made it!!! After hours of delayed flights, missed connections, fully booked alternatives, planes turned back due to faulty toilets, no sleep and extremely bad treatment at the hands of US Airways we got to Houston! 5 of us … Continue reading

A short time ago I wrote about some of our work analysing the xenon in zircons from the Jack Hills region of Australia, the oldest known material on Earth. If you think trying to unravel xenon contributions from 2 sources … Continue reading

Jack Hills, Western Australia – a hot, dry and barren place where very little lives. But it is here that the oldest known materials on Earth have survived from shortly after the formation of the Earth until the present day. … Continue reading
