The thin section and polished section collection comprises over 5000 covered soil thin sections (0.03 mm) and polished sections (sawn sample disk) from numerous archaeological sites (focal area Switzerland) from the Palaeolithic to modern times.

The collection includes archaeological layers from a wide variety of contexts (including lakeside settlements, walking levels, house floors, pits, ditches, ovens, latrines, farmland, demolitions, stables, dark earth, etc.) as well as pedological thin sections and natural deposits (fluvial and limnic deposits, loess, peat, periglacial phenomena, etc.).

This is supplemented by comparative collections of coprolites, organic remains and ceramics (both archaeological and recent samples), histotaphonomy and experiments (e.g. trampling and firing experiments).

The collection is available to researchers and students on request:
