The pedons represent deposits of different volcanoes (Mt.Tangkuban Perahu, Mt. Patuha and Mt. Papandayan), with different ages (Pleistocene, Holocene) and various types of volcanisms (andesitic, basaltic), in three agroclimatic zones (A, B1, B2). Undisturbed soil samples were taken from every identifiable horizon for thin section preparation. Observations were made with a magnifying le ns, binocular stereomicroscope, polarization microscope, and scanning electron microscope (SEM). The result demonstrated that micromorphological characteristics of volcanic soils developed from different ages, types of parent material and climate were different through their c/f related distribution patterns, c/f 2µ ratios, sorting, infillings and coatings of voids, and microstructure.
