The boots (also Lett or Lätt ) is an often silty to sandy clay with a low addition of lime . The sediment is gray in color, but other colors are possible. The word is a name for weakly solidified slate from the late Paleozoic and Mesozoic Era ; its use is not recommended for the corresponding unconsolidated rock from the Cenozoic Era .
Similar to loam , the mineral components and good storage capacity usually result in fertile soils .
If the Latvian fills a gap , it is called a gap . Thin coverings on fractured surfaces are called Lettenbestege .
Letten comes from the colloquial language and has the meaning of 'unusable rock' (mostly clays) up to Upper German dialectal living, generally 'damp, muddy soil, loamy mud'. The Prussian King Friedrich Wilhelm IV, for example, refused the hereditary emperor title offered to him in 1849 with the remark that it was only baked "from dirt and Latvian".
Several geographical names are derived from the occurrence of the rock, e.g. B. Lettenbach and Lettenhof , as well as various family names.
