Reported analyses provide information about the size and shape of allophane and imogolite particles and their internal structure. Materials studied are from Japanese weathered pumices and ash. Imogolite and allophane are different in their framework structures. A Si- or Si(Al)-tetrahedral sheet, rather than an Al-octahedral sheet, apparently constitutes the allophane framework structure.-D.F.B.
