New Group Paper: Identifying primitive noble gas components in lunar ferroan anorthosites

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

New group paper: A new way to investigate the history of the surface of the Moon.

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

New Group paper: The I-Xe chronometer and its constraints on the accretion and evolution of planetesimals

This gallery contains 2 photos.

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

Using these “lasers” we punch a hole…

This gallery contains 3 photos.

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

Xenon in Zircons: Unravelling Their History

This gallery contains 4 photos.

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

The oldest thing on Earth

This gallery contains 4 photos.

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
