Particles of the volcanic light soils

Abstract

(1) It is not recognized that the difference of the form of sand and silt between the volcanic light soils and un-volcanic light soils.
(2) The form of clay minerals has disatinction little among the each test soils as shown: Electron micrograph (1) - (5).
(3) Judging to the result of the Erectron microscopy and the defferential thermal curve, clay of the volcanic light soils in general contains Allophane, while un-volcanic soils contain Hydrated halloysite.
But I recognized the qualitative difference among the clay minerals, yet do not clear up differece of form of the clay mineral particles. It may be some particulations between the form of soil particles and stickiness, as still more I intend to research for the soil particles.
