Catena (floor)

from Wikipedia, the free encyclopedia
Schematic representation of a catena. The soil gains in tread depth and horizons from right to left along the relief

A catena (Latin for chain ), relief sequence or toposequence is in soil science the section through a soil landscape or the special sequence of soil profiles along a relief , whereby the profiles have similar parent rocks (C horizons ) and the relief also has similarities. Usually a catena runs from the highest point in the relief to the lowest. This distinguishes the catena from a transect that only has to meet the requirements that all measuring points are in a straight line.

The floor has different profiles along a slope. This section through a sequence of soil profiles is called Catena.

Concept history

The designation comes from Geoffrey Milne from 1935 in the article " Some suggested units for classification and mapping, particularly for East African soils " (in Soil Research Volume 4. Pages 183-198). The geologist Paul Vageler (1882–1963) wrote in 1942: “The basic idea of ​​the Catena method is so simple and logical that it not only appears like the egg of Columbus, but also like a flatness: In every natural terrain ... There must always be a transport of soil material from the relative heights to the relative depressions ..., so very specific series of merging soil and profile types ... must be arranged. "
