Two weathered pumice samples were used for this study. The interior structure of spherical halloysite particles in the samples were examined by EM in combination with potassium acetate to induce gentle breaking up of the spherical particles. The IR spectra of oxalate-oxalic acid soluble fractions were examined by differential IR spectroscopy. The results indicated that spherical halloysite particles have concentric and discontinuous stacking of kaolin unit layers and a cavity in the core. No substantial amount of allophane occurs but some defect structure intermediate between allophane and halloysite probably occurs in the spherical particles. -K.O.
