Definizione

Pietsch Johannes S., Wetzel Andreas, Jordan Peter (2016) : A new lithostratigraphic scheme for the Schinznach Formation (upper part of the Muschelkalk Group of northern Switzerland). Swiss J. Geosc. 109/2, 285-307

The Kaisten Bed represents the uppermost oolitic interval of the Schinznach Formation. It comprises the oolitic intervals described for the Wutach region (e.g. Paul 1971), the lower course of the Aare River (Nagra 1984; Matter et al. 1987; Brüderlin 1971), and the macrofossil-rich oolitic strata in the Kaisten area (‘‘Kaistener Schichten’’; Merki 1961). The ooids in this interval are completely dolomitised (Merki 1961; Rieser 1964) and often ooid shapes can only be recognised under the microscope.

While most occurrences of the uppermost oolitic interval were described either from boreholes (Riniken, Matter et al. 1987; Beznau, Nagra 1984) or from outcrops in

adjacent Germany (Brüderlin 1971; Paul 1971), the type locality of the oolitic ‘‘Kaistener Schichten’’ proposed by Merki (1961) in the Aargau Tabular Jura was chosen to be

the type region of the Kaisten Bed as well. Contrary to the ‘‘Kaistener Schichten’’ the Kaisten Bed only comprises the oolitic strata within the bivalve- and gastropod-rich strata

described by Herb (1957). For discussion of the lithostratigraphic definition of the oolitic intervals see below.
