Exploring Earth with high-temperature isotope geochemistry.

News and Highlights

We discovered primordial neon in Baffin Island lavas!

See our recent publication in Earth and Planetary Science Letters.

Carbonatites are rare igneous rocks composed primarily of carbonate minerals. Our recent paper about a carbonatite volcano in Afghanistan highlights the important role of fluids during carbonatite volcanism...

See our paper about helium in olivine

"Helium distributions in ocean island basalt olivines revealed by X-ray computed tomography and single-grain crushing experiments" - Horton, Farley, and Jackson

​

We discovered that helium and CO2 are hosted in fluid inclusions inside olivine crystals. Carbon escapes as grains decrepitate (crack due to a buildup of overpressure in the inclusions) as they ascend in hotspot lavas. Helium probably diffuses through the olivine lattice.

Successful 2018 field season on Baffin Island!

Paul Asimow, Joe Biasi, and I had an adventurous field season in the Arctic Circle in August, 2018. We explored the high 3He/4He lavas that erupted as Greenland and Canada rifted apart. These rocks potentially hold clues about the deepest, oldest domains in Earth's mantle.

New laser ablation system

Our ICP-MS lab is now equipped with a state-of-the-art ASI RESOlution excimer (193nm) laser. This instrument can ablate geologic samples with a beam as small as 2 microns (less than 1/10th the thickness of a human hair) and send that material to a multi-collector ICP-MS (Neptune Plus), single-collector ICP-MS (Element), and/or quadrupole MS for isotopic analysis.
