About FergusoniteHide

Robert Ferguson of Raith

Name:

After Robert Ferguson (1767- 3 December 1840), Scottish landowner, politician and mineral collector

Synonym of:

Fergusonite-(Ce), Fergusonite-(Nd), Fergusonite-(Y)

Fergusonite is one of the species groups or series that was originally described as a single species, based on the standards of the time. Subsequently, with the advancement of science, several separate species were defined (Y-, Ce- and Nd-dominant). This file covers the data when all were one, simply "fergusonite."

Monoclinic dimorphs are summarised under the name "β-Fergusonite".
