This study of a number of fragipan soils derived from a wide range of parent materials was undertaken to test an hypothesis concerning fragipan formation which had as its foundation data obtained from loessial soils. Particle size distributions and selected chemical properties were determined and comparisons of the data for the Bx and adjacent horizons were made. The portion of the original hypothesis suggesting that fragipan soils were severely leached prior to pan formation and that pan formation resulted from tight packing of dispersed clay particles is acceptable with certain limitations. On the other hand, it cannot be accepted that Ca:Mg or Ca:Mg + Na ratios are factors of general importance in fragipan formation.
