Meteorización y erosión en el subdesierto de Tabernas

Abstract

[ES]El área acarcavada, o malpaís, de mayor extensión del sudeste peninsular, en el sub-desierto de Tabernas, Almería, es un mosaico de teselas en donde se encuentran concentradas muchas de las formas de erosión de la mayoría de paisajes fluviales, y muy en especial los de zonas áridas. Un clima Mediterráneo semiárido, cercano a su extremo más árido, y una particular litología sobre una alternancia de margas yesíferas y calcarenitas explican la enorme variedad de geoformas de este paisaje. Si bien la geomorfología de la zona sugiere elevadas tasas de erosión, las particulares condiciones climáticas, con escasez de eventos de elevada intensidad y/o magnitud impiden que la erosión sea elevada. Se explican sucintamente los principales procesos geomorfológicos que han configurado este malpaís: desde la meteorización de la principal roca madre, la marga yesífera, pasando por la formación de regolitos, suelos y sus costras superficiales y un conjunto muy particular de comunidades vegetales que conviven con los procesos erosivos y las peculiares condiciones climáticas, los grupos de factores ecológicos más importantes y típicos de la zona.

[EN]The largest badlands in SE Spain, within the Tabernas sub-desert (Almería, Spain) is a mosaic of physiographic units concentrating most of the water erosion features of fluvial landscapes, specially those from arid regions. A Mediterranean semiarid climate in its driest end, along a main lithology on gypsum-calcaric mudstones, all explain the large variability of this landscape. Though the local geomorphology might suggest large erosion rates, the special climatic conditions of the area, with scarce rainfall events usually of low magnitude and intensity, restrict soil erosion. In this chapter the main geomorphic processes which have shaped the area are reviewed: from weathering, to regolith and soil formation, along with the indispensable role played by plant cover and its co-evolution with erosion.
