Estudio fisico-químico y micromorfológico de intergrados andosol - tierra parda oligotrófica, en un perfil complejo

Abstract

[ES] Se estudian las características morfológicas, físico-químicas y micromorfológicas de un perfil complejo, Las Lajas, en la región de Las Mercedes, en Tenerife (Islas Canarias). El perfil se haya situado sobre formaciones eruptivas volcánicas terciarias, pero está rejuvenecido por erosión y coluvionamiento. Presenta en la parte superficial un suelo con reacción positiva al ensayo de la NaF y un horizonte A muy humificado, tiene características de suelos ándicos como son la contextura isótica y el predominio de huecos de empaquetamiento. A continuación se presentan varios paleosuelos y sedimentos de suelos con rasgos de suelos ferraliticos tropicales; el denominado II contiene abundante gibsita y en todos ellos hay translocación de arcilla.

[EN] The morphological, physicochemcial and micromorphological characteristics of a complex soil profile from Las Mercedes area. Las Lajas, in tenerife (Canary Islands) are studied. Tje soil is placed on Tertiary eruptive volvcanic formations and is affected by erosion and colluvial phenomena. The complex profile has a surficial part giving a positive reatcion to the Na F test. The A horizon shows strong humification and andic soil characteristics such as isotic fabric and abundant packing voids and several paleososls and soil sediments with tropical ferallitic features can be recognizad underneath. Abundant gibbsite is identified in the II layer. All observed paleosols show signs of clay translocation.
