Horizonte en el subsuelo, cementado por la sílice iluvial a un grado tal que menos del 50 % del volumen de fragmentos secados al aire se enfrían en el agua o durante una inmersión prolongada en ácido clorhídrico (HCL). Pueden variar en cuanto al grado de cementación por sílice. Comúnmente contienen cementos adicionales, principalmente carbonato de calcio."@es, "A duripan (L. durus, hard; meaning hardpan) is a subsurface horizon that is cemented by illuvial silica to the degree that less than 50 percent of the volume of air-dry fragments slake in water or during prolonged soaking in acid HCl). Duripans vary in the degree of cementation by silica. In addition, they commonly contain accessory cements, chiefly calcium carbonate."@en ;
