Bekaert D, Barry P, Broadley M, Byrne D, Marty B, Ramirez C, et al.
Sci Adv . 2023 Apr; 9(15):eadg2566. PMID: 37058557
Mantle-derived noble gases in volcanic gases are powerful tracers of terrestrial volatile evolution, as they contain mixtures of both primordial (from Earth's accretion) and secondary (e.g., radiogenic) isotope signals that...

Broadley M, Bekaert D, Piani L, Furi E, Marty B
Nature . 2022 Nov; 611(7935):245-255. PMID: 36352134
Volatile elements such as hydrogen, carbon, nitrogen and oxygen are essential ingredients to build habitable worlds like Earth, but their origin and evolution on terrestrial planets remain highly debated. Here...

Okazaki R, Marty B, Busemann H, Hashizume K, Gilmour J, Meshik A, et al.
Science . 2022 Oct; 379(6634):eabo0431. PMID: 36264828
The near-Earth carbonaceous asteroid (162173) Ryugu is expected to contain volatile chemical species that could provide information on the origin of Earth's volatiles. Samples of Ryugu were retrieved by the...

Okazaki R, Miura Y, Takano Y, Sawada H, Sakamoto K, Yada T, et al.
Sci Adv . 2022 Oct; 8(46):eabo7239. PMID: 36264781
The Hayabusa2 spacecraft returned to Earth from the asteroid 162173 Ryugu on 6 December 2020. One day after the recovery, the gas species retained in the sample container were extracted...

Barrat J, Chaussidon M, Yamaguchi A, Beck P, Villeneuve J, Byrne D, et al.
Proc Natl Acad Sci U S A . 2021 Apr; 118(11). PMID: 33836612
The age of iron meteorites implies that accretion of protoplanets began during the first millions of years of the solar system. Due to the heat generated by Al decay, many...

Broadley M, Barry P, Bekaert D, Byrne D, Caracausi A, Ballentine C, et al.
Proc Natl Acad Sci U S A . 2020 Jun; 117(25):13997-14004. PMID: 32513744
Identifying the origin of noble gases in Earth's mantle can provide crucial constraints on the source and timing of volatile (C, N, HO, noble gases, etc.) delivery to Earth. It...
7.
Bekaert D, Broadley M, Marty B
Sci Rep . 2020 Apr; 10(1):5796. PMID: 32242104
The origin of terrestrial volatiles remains one of the most puzzling questions in planetary sciences. The timing and composition of chondritic and cometary deliveries to Earth has remained enigmatic due...

Marty B, Bekaert D, Broadley M, Jaupart C
Nature . 2019 Nov; 575(7783):485-488. PMID: 31748723
The exchange of volatile species-water, carbon dioxide, nitrogen and halogens-between the mantle and the surface of the Earth has been a key driver of environmental changes throughout Earth's history. Degassing...
9.
Broadley M, Sumino H, Graham D, Burgess R, Ballentine C
Geochem Geophys Geosyst . 2019 Apr; 20(1):277-294. PMID: 31007626
Halogens are primarily located within surface reservoirs of the Earth; as such they have proven to be effective tracers for the identification of subducted volatiles within the mantle. Subducting lithologies...

Bekaert D, Broadley M, Delarue F, Avice G, Robert F, Marty B
Sci Adv . 2018 Mar; 4(2):eaar2091. PMID: 29507886
Understanding the composition of the Archean atmosphere is vital for unraveling the origin of volatiles and the environmental conditions that led to the development of life. The isotopic composition of...
