The Lithostratigraphic Lexicon of Switzerland lists the valid name of the lithostratigraphic units, describes their lithology and provides details on distribution, upper and lower contacts, type locality and references.
The lexicon is a handy reference for geologists from academia and industry. It is an important tool for the creation of geological maps. The Swiss Committee on Stratigraphy (SCS) and the Swiss Geological Survey manage the lexicon, continually work on and expand it.
Your feedback is important: send us your comments and suggestions about the lexicon in general as well as material contributions on individual units.
