Extract

Recent examination of clay-materials from several different sources has suggested to us the existence of a type of chlorite capable of the same kind of expansion along the c-axis by imbibition of glycerol, as is shown by montmorillonoids, vermiculites and halloysites. The expansion occurs within the range of 14 kX to 18 kX.

It is necessary to discuss the definition of chlorite in this connexion, since such expansion is not regarded as characteristic of any of the minerals to which the name has been given. The characteristics by which chlorites are generally identified from their X-ray diffraction patterns are twofold: (1) they give basal reflexions at approximately 14 kX and submultiples, the first four orders being usually strong and of comparable intensity, though differing in different species of chlorite; (2) these reflexions persist after heating at 500°C.
