THE STRUCTURE OF THE CHLORITES [PDF]
Proceedings of the National Academy of Sciences, 1930 By the application of the same methods of investigation as those used in the study of the micas,(1) I have determined the structure of the chlorites, a group of minerals morphologically similar but distinctly different in chemical composition. This structure is described in the following paragraphs.
