Jointed bedrock

Spheroidal weathering is a form of chemical weathering that affects jointed bedrock and results in the formation of concentric or spherical layers of highly decayed rock within weathered bedrock that is known as saprolite. When saprolite is exposed by physical erosion, these concentric layers peel (spall) off as concentric shells much like the layers of a peeled onion. Within saprolite, spheroidal weathering often creates rounded boulders, known as corestones or woolsack, of rel…

NettetThe joint bedrock was exposed to the fly ash reservoir because the landslide removed the clayey colluvium and/or residual soil overlying the jointed bedrock that formed a natural impervious barrier to seepage. This sediment-laden seepage initially was a great concern because of the potential for erosion and piping in earth dams.
