Appl Radiat Isot. 2017 Dec;130:224-229. doi: 10.1016/j.apradiso.2017.10.006. Epub 2017 Oct 05.

As an iron is the main structural component of nuclear power plants as well as future fusion power plants, the validation of neutron incident data libraries of iron is a must. Presented paper fits into ongoing validation activities and...

Iron isotope fractionation during magmatic differentiation in Kilauea Iki lava lake.

Science (New York, N.Y.)

Teng FZ, Dauphas N, Helz RT.
PMID: 18566283
Science. 2008 Jun 20;320(5883):1620-2. doi: 10.1126/science.1157166.

Magmatic differentiation helps produce the chemical and petrographic diversity of terrestrial rocks. The extent to which magmatic differentiation fractionates nonradiogenic isotopes is uncertain for some elements. We report analyses of iron isotopes in basalts from Kilauea Iki lava lake,...
