Modelling magnetite biomineralisation: the interactions of proteins and Fe3O4 surfaces [PDF]

The biosynthesis of magnetite is the earliest known example of biomineralisation; how-ever, much of the detailed atomistic mechanisms by which the process occurs are unknown. Within the bacterial strain Magnetospirillum magneticum AMB-1, the formation of

Appraisal of Six Natural Mica Reference Materials for In Situ Rb‐Sr Geochronology

Geostandards and Geoanalytical Research, EarlyView.
Key Points Evaluated six natural mica reference materials for in situ LA‐ICP‐MS/MS Rb‐Sr geochronology using geochemical, microstructural and isotopic characterisation. Identified robust primary reference materials: Mount Dromedary biotite (99.37 Ma) and Mica‐Fe biotite (307.75 Ma). La Posta biotite and Högsbo muscovite are suitable secondary reference
