New paper on Moon’s origins and ancient terrestrial heterogeneity

By parai on September 10, 2020 in news

A new collaborative paper is out in Space Science Reviews! This was the result of the ISSI Europlanet Workshop “Reading Terrestrial Planet Evolution in Isotopes and Element Measurements” held in October 2018 in Bern, Switzerland. The paper discusses geodynamical models of lunar origin...

New review papers out!

By parai on August 7, 2019 in news

This summer has brought two new review papers: One in Annual Review of Earth and Planetary Sciences that provides an overview of noble gas constraints on the origins of Earth’s volatiles, volatile delivery during accretion, the timing and extent of volatile loss, early-formed heterogeneitie...

There and Back Again: Mantle xenon isotopes have a tale to tell

By parai on August 8, 2018 in news

NEW August 8, 2018 Our new paper published in Nature presents a model of xenon (Xe) cycling between the deep Earth and surface reservoirs. Volatiles (such as water, carbon dioxide, nitrogen and the noble gases) are outgassed from the Earth’s mantle due to volcanic activity. Surface volatile...

Congratulations to Savannah!
