Hello all,
I need a bit of help. People writing in the discipline of clay
mineralogy and other related disciplines (e.g., surface studies, soils,
general mineralogy), seem to use the terms epitaxial and topotaxial
interchangeably. My general notion is that an epitaxial overgrowth has two
xllographic dimensions in common with its host, whereas topotaxial has
three. What I need is a proclamation by some appropriate nomenclature
committee. Can anyone refer me to a source for definitions of these terms?
We would like to use them in the 2nd edition of Moore and Reynolds, X-Ray
Diff. and the Ident. and Analysis of Clay Minerals.
Thanks for whatever you can do.
