Abstract

The birefringence of complexes of montmorillonite with aromatic liquids depends on the type of liquid, and this fact was used to determine the proportion of expanding layers in some partly expanding minerals. A simple method of assessing samples for the presence of expanding minerals probably could be devised on the same lines.
