ResumenThe micromorphological characteristics of the Chio and the Chinyero profiles are studied. These soil profiles are representative Vitrandept soils of Tenerife Island. The soils qre very young, formed from recent pyroclastic rocks under a vegetation of Pinus Canariensis. They have a loose, or very loose, isotic fabric (X 63). Coarse/fine related distributions correspond to intergrades between enaulic type towards the soil surface and monic type towards the depth. Skeleton grains are very abundant: there is a predominance of lapilli and other volcanic rocks fragments, of pyroxenes and amphiboles, of opaque crystals and of volcanic glass. Aggregates formed from rocks alteration qre abundant. They have <0.2 mm size : the rock structure is only recognized in the central part of the aggregate. The size, roundness and alteration type of the skeleton grains confirm the colluvial nature of the A horizon. The source of the colluvial material is different in the two soils. Humus form is Syrosem. Fungal hyphae and sclerotia are frequently present.
