Abstract
The relatively homogeneous basalt rocks of the Faeroe Islands have been subjected to low grade metamorphism to produce smectite type and zeolite crystals in addition to the native minerals. Pedogenesis of the glacial drift produced from this rock apparently rapidly converts smectite into a degraded variety of chlorite.Although minor amounts of illite and kaolin were recorded, these are considered to be lithorelics. Quartz is entirely absent. A modest range of soil groups have developed under variable environmental conditions. These acid soils are strongly humic, have high cation exchange capacities, and have low base saturation.
