Summary In the Ecuadorian Cordillera, the hardened volcanic ashes (cangahuas) account for 15% of the cultivated area. The soil resulting from the fragmentation of these materials, generally by heavy machinery, shows an apparent stable millimetric str

Clast shape preferred orientation or anisotropy of magnetic susceptibility (AMS) data are increasingly used to constrain the source location of ash flow tuffs. Little attention has been paid to processing of these directional data for the accurate an

Weathering and neoformation of allophane, imogolite and halloysite in volcanic ash soils have been studied extensively in humid climates but little data are available on these soils in arid and semi-arid conditions. Weathering and soil formation unde
