The structure of the micas and related minerals

Pauling, Linus

Abstract

With the aid of the general principles(1) governing the structures of complex ionic crystals I have formulated a structure for talc, pyrophillite, the micas, and the brittle micas which is substantiated by the x-ray examination of the minerals, explains their remarkable physical properties, and leads to a general chemical formula unifying the widely varying analyses reported for different specimens. This structure is described in the following paragraphs.

Copyright © 1930 by the National Academy of Sciences. Communicated January 16, 1930. I wish to acknowledge the assistance of Mr. J. Sherman in the preparation and analysis of the x-ray photographs. A further account of the x-ray investigation of these minerals and a comparison of the suggested general formulas with the reported chemical analyses will be published in the Zeitschrift fuir Kristallographie.
