Report of the Clay Minerals Group Sub-Committee on Nomenclature of Clay Minerals

This sub-committee consisting of Mr G. Brown (Chairman), Dr M. H. Hey, Dr D. M. C. MacEwan and Dr R. C. Mackenzie was asked to make proposals for the nomenclature of clay minerals and these proposals were presented in part at a C.I.P.E.A. meeting in Paris in July, 1954, where some useful discussion ensued. The outcome of that meeting was a suggestion that the proposals be published more fully. It is important to remember that these are proposals for consideration and not a set of rules. The Clay Minerals Group would welcome comments on these proposals (adverse or otherwise) or the comments may equally well be sent to C.I.P.E.A. Addresses to which comments, suggestions, criticisms, etc., should be sent are : For the Clay Minerals Group : Mr G. Brown, Pedology Department, Rothamsted Experimental Stn., Harpenden, Herts., England. For C.I.P.E.A. : Dr W. F. Bradley, Illinois State Geological Survey, Urbana, Illinois, U.S.A.
