A duripan can sometimes be broken up by earthquakes or periods of alternate wetting and drying that cause small volume changes.
2.
It cannot be considered a duripan until the cracks and gaps that allow roots to penetrate are 10 cm or more apart.
3.
These landforms are characterized by strongly developed soils that usually have a relatively impermeable layer ( claypan or silcrete duripan ) in the subsoil.
4.
The weathered silica is mostly transported by water into the subsoil, where it precipitates and forms microaggregates that gradually grow into a full-fledged duripan.
5.
It is a general term ( not to be confused with duripan ) for a zone of chemical sedimentary bodies through pedogenic and ( or ) non-pedogenic processes.
6.
The parent material of duripan soils usually does not contain a large amount of calcium carbonate, and if there is an abundance of calcium, a Petrocalcic Horizon can form in conjunction with the duripan.
