Micas ionic site

THE ROLE OF SIMS IN THE CONTEXT OF A MULTIMETHODIC APPROACH CHARACTERIZATION OF THE IONIC SITE OF MICAS... [Pg.1034]

Actinium is similarly easy to find a proxy for. It forms large trivalent cations with an ionic radius of 1.12 A in Vl-fold coordination. This is somewhat larger than La (1.032 A), which we will adopt as a proxy. The partitioning behavior of the lanthanides (denoted collectively Ln) is sufficiently well understood to make this a prudent choice. In some minerals, however, the larger size of Ac, may place it onto a larger lattice site than the lanthanides. This possibility should be considered for minerals with very large cation sites, such as amphiboles and micas. [Pg.81]
