Soils at Imaggeo: Gypsum concretions in a soil horizon
Antonio Jordán, University of Seville, Sevilla, Spain Most Gypsisols are formed when gypsum (calcium sulfate) from gypsiferous parent materials is dissolved and moves through soil water, precipitating in an accumulation soil horizons. Triassic rock outcrops in almost all Andalusia consist mainly of red and variegated clays and in some cases by clays of different colors …[Read More]
