Early planetesimal differentiation and late accretion shaped Earth’s nitrogen budget [PDF]
Nature CommunicationsThe relative roles of protoplanetary differentiation versus late accretion in establishing Earth’s life-essential volatile element inventory are being hotly debated.

Meteoritics & Planetary ScienceThe occurrence of forsteritic olivine in EH enstatite chondrites is indicative of bulk disequilibrium. In MgO‐rich magmatic systems, forsterite can either crystallize as a liquidus phase or be produced during peritectic melting of enstatite.

Bioweathering of a reduced chondritic material : implications for Enstatite chondrite
, 2011 The aim of this study is to investigate the mineralogical and chemical processes which take place during the bioweathering of an enstatite chondrite by bacteria. Synthetic enstatite chondrites were made in laboratory in order to begin this complex study with simplified and well-defined materials.

Northwest Africa 2526: A partial melt residue of enstatite chondrite parentage
, 2008 NWA 2526 is a coarse-grained, achondritic rock dominated by equigranular grains of polysynthetically twinned enstatite (~85 vol%) with frequent 120 triple junctions and ~10-15 vol% of kamacite + terrestrial weathering products. All other phases including

Evolution of a Water-rich Atmosphere Formed by a Giant Impact on an Earth-sized Planet
The Astrophysical Journal, 2023 The atmosphere of a terrestrial planet that is replenished with secondary gases should have accumulated hydrogen-rich gas from its protoplanetary disk.

Progress in Earth and Planetary Science, 2022 Enstatite chondrites are a small clan of meteorites, only ~ 1% out of all meteorite collection. However, they are the most reduced meteorites and have almost identical isotopic compositions to those of the Earth, suggestive of significant contributions ...

Dating and Tracing the Origin of Enstatite Chondrite Chondrules with Cr Isotopes
Astrophysical Journal, 2020 Chondrules are major components of chondrites and are believed to drive the accretion of planetary embryos. As such, constraining the timing and origin of chondrules is central for understanding the early evolution of the solar system and the formation ...

Chemical studies of enstatite chondrites
, 1996 The unique mineral and chemical composition of enstatite chondrites has been difficult to explain. Contrary to the conclusions of other workers, there is no evidence for a significant chemical difference between EH and EL chondrites, except in bulk S ...
