An exfoliation dome is a geological formation characterized by a large, rounded rock mass that has undergone exfoliation, a process where layers of rock peel away from the surface due to pressure release and weathering. This typically occurs in granite or other coarse-grained rocks when overlying material is removed through erosion, leading to a reduction in pressure. As the rock expands, it fractures in thin, curved sheets, creating the dome shape. Notable examples include Half Dome in Yosemite National Park.

Which type of weathering produces an exfoliation dome?

In some case chemical weathering can cause this (where new crystals form from old ones but where the volume of the new crystals is not the same as the original). In other cases the weathering process is temperature driven by water entering the porous layer of a weathering rock and freezing. This can split the rock parallel to the surface, giving it exfoliation layers. Some texts also imply that exfoliation domes are produced by by removal of vertical pressure relieving paleo stresses in the rock, this however would not be a weathering process.

What process uses exfoleation domes?

Exfoliation domes are geological features formed by the repeated expansion and contraction of rocks due to temperature changes. This process, known as thermal cycling, causes the outer layers of rocks to peel away in dome-like structures.


What process forms exfoliation domes?

The formation of an exfoliation dome begins with sheeting, when large masses of igneous rock, particularly, granite, are exposed by erosion, concentric slabs begin to break loose, this process occurs in part because of the great reduction in pressure when the overlying rock is eroded away, a process called unloading, and accompanying this unloading, the outer layers expand more than the rock below and thus separate from the rock body. Continued weathering eventually causes the slabs to separate and spall off, creating exfoliation domes.


exfoliation?

Exfoliation refers to the process of removing dead skin cells from the surface of the skin. It helps to improve the skin's appearance, texture, and overall health.


How can exfoliation help revitalize your skin?

Exfoliation removes dead skin cells, unclogs pores, and stimulates cell turnover, resulting in a brighter and smoother complexion.
