DOI: 10.1007/978-981-13-3639-3_14
Abstract: Earth’s early surface environment had great influence on the origin of life through formation of its building blocks. From geological and geochemical evidence, the Earth’s atmosphere and oceans appear to have existed since a very… read more here.

DOI: 10.1016/j.epsl.2017.09.028
Abstract: Abstract The abundance of moderately volatile elements, such as Zn and Ga, show variable depletion relative to CI between the Earth and primitive meteorite (chondrites) parent bodies. Furthermore, the first solar system solids, the calcium–aluminum-rich… read more here.

DOI: 10.1016/j.epsl.2017.12.042
Abstract: Abstract The depletion pattern of volatile elements on Earth and other differentiated terrestrial bodies provides a unique insight as to the nature and origin of planetary building blocks. The processes responsible for the depletion of… read more here.

DOI: 10.1016/j.epsl.2019.05.041
Abstract: Abstract Previous studies have reported that the relative abundances of volatile elements in the silicate Earth are non-chondritic. The abundance and distribution of volatile elements in terrestrial planets would have been predominantly controlled by planetary… read more here.

DOI: 10.1016/j.icarus.2018.08.020
Abstract: Abstract Vesta, the second-largest body in the asteroid belt, is believed to be a prime example of a rocky protoplanet. Studies of the HED (Howardite–Eucrite–Diogenite) meteorite suite, considered to be sourced from the mantle of… read more here.

DOI: 10.1126/science.abn1783
Abstract: Meteorites record processes that occurred before and during the formation of the Solar System in the form of nucleosynthetic anomalies: isotopic compositions that differ from the Solar System patterns. Nucleosynthetic anomalies are rarely seen in… read more here.
