ytbergarter
Ytbergarter is a geological term used to describe rock units that are exposed at the Earth's surface or within the shallow subsurface and have undergone weathering and alteration due to exposure. The name derives from Swedish roots, with yt meaning surface and bergarter meaning rock types; in English-language summaries it is often described as surface rocks or near-surface rock units. In regional geology and engineering geology, ytbergarter serves to distinguish rocks that are currently part of the weathered crust from deeper, relatively intact bedrock.
Characteristics of ytbergarter typically include signs of weathering such as a rind of alteration, soil development
Formation and distribution occur through processes that expose or bring rocks closer to the surface, such as
Usage and classification notes: ytbergarter is not a strict lithological category but a practical term used
