Desert Pavement and Vesicular Layer of Some Soils of the Desert of the Lahontan Basin, Nevada1

  1. M. E. Springer2



Desert pavement and vesicular layer are described as distinct horizons of some Gray Desert soils. Distribution of > 2-mm. and < 2-mm. particles in the profile along with laboratory tests suggest that accumulation of gravel and stones at the surface to form a desert pavement is not due solely to removal of finer material by wind or water. There has also been some upward movement of coarse fragments from the nearly stone-free layers below.

Some properties of vesicular layers are pointed out by field and laboratory studies. Natural vesicular structure was destroyed by sieving and a new, but similar, structure formed by merely wetting and drying the soil. This led to a hypothesis for origin of the vesicular layer as a pedogenic horizon.
