Iron isotopes constrain core chemistry

Science, 2016
Geochemistry The overall composition of Earth's core is an important constraint on the chemistry and evolution of our planet's interior. A longstanding problem has been determining the minor element contribution to its predominately iron-nickel alloy. Based on the iron isotope fractionation of various iron alloys with pressure, Shahar et al.

Pressure-dependent isotopic composition of iron alloys

Science, 2016
Iron isotopes constrain core chemistry The overall composition of Earth's core is an important constraint on the chemistry and evolution of our planet's interior. A longstanding problem has been determining the minor element contribution to its predominately iron-nickel alloy.

A Radioactive Isotope of Iron

Nature, 1936
IT was shown by Fermi and co-workers1 that the activity induced in iron by neutron bombardment is due to an isotope of manganese. The isolation of an active iron isotope has not been reported. By means of the sensitive tube counter outfit2 in this institute, it was found that active iron can be isolated from cobalt which has been irradiated with ...

Iron isotope fractionation between aqueous ferrous iron and goethite

Earth and Planetary Science Letters, 2010
Abstract The equilibrium Fe isotope fractionation factor between aqueous Fe(II) and goethite has been experimentally measured to be − 1.05 ± 0.08‰ in 56 Fe/ 54 Fe (2 σ ) at 22 °C, using the three-isotope method. Experiments were done using two sizes of goethite (81 × 11 nm and 590 × 42 nm), and the experimental products were subjected to serial ...
