Low-spin ferrous iron suppresses mantle oxidation beyond Earth-like pressures

Alice Girani, Sylvain Petitgirard, Sergey Yaroslavstsev +5

The Earth's mantle has elevated Fe relative to those of other rocky bodies, yet the oxidation- and electronic state of iron at extreme pressures is poorly known. We present…

The Ni isotopic composition of Ryugu reveals a common accretion region for carbonaceous chondrites

Fridolin Spitzer, Thorsten Kleine, Christoph Burkhardt +88

The isotopic compositions of samples returned from Cb-type asteroid Ryugu and Ivuna-type (CI) chondrites are distinct from other carbonaceous chondrites, which has led to the sugge…

Simultaneous observation of concurrent two-dimensional carbon and chlorine/bromine isotope fractionations of halogenated organic compounds on gas chromatography

Caiming Tang, Jianhua Tan

It has been reported that isotope fractionation can occur on gas chromatography (GC), yet little is known about concurrent dual-elements isotope fractionations on GC. Revelation of…
