TL;DR: In this paper, a polygenetic soil on tertiary basalt in the north of Lanzarote (Canary Islands, Spain) was examined, which took place in a semiarid climate since the end of the tertiary period.
Abstract: Ein polygenetischer Boden auf tertiarem (Miozan) Basalt im Norden Lanzarotes (Kanarische Inseln, Spanien) wird untersucht und die bodenbildenden Prozesse seit dem ausgehenden Tertiar in einem semiariden Bereich werden rekonstruiert. Die Auswertung der Feld- und Laborarbeiten (Carbonat, Kornung, oxalat- und dithionitlosliche Oxide, KAK, Tonminerale, Mikromorphologie) lies die Entwicklungsgeschichte des Profils erkennen. Seit dem Miozan wurden mindestens sieben zeitlich aufeinanderfolgende und durch Erosion, Materialzufuhr und/oder Klimaanderungen ausgeloste Bodenbildungsphasen wirksam. Basalt Weathering and Soil Development since the Middle Tertiary on Lanzarote, Canary Islands - The Profile Malaya Chica A polygenetic soil on tertiary (miocene) basalt in the north of Lanzarote (Canary Islands, Spain) was examined. Soil development was reconstructed, which took place in a semiarid climate since the end of the tertiary period. The interpretation of field and laboratory results (carbonate, grainsize distribution, oxalate and dithionithe soluble oxides, CEC, clay minerals, micromorphology) explained the history of development. Since the miocene at least seven consecutive phases of soil development took place induced by erosion, volcanic and colluvial sedimentation and/or climatic changes.
