Jahreswarven im Sennesander?

Adolf Deppe & Fritz Fezer
The western edge of the Teutoburger Wald near Bielefeld consists of Turon limestones. They are covered by thick layers of weathered lime plates. We found the same material in the plain „Senne", where the plates become smaller, loose their edges and are interrupted by sand layers. We suppose the glacier rivers transporting plates out of the warm Turon edge in spring and sand out of the Inlandeis in summer.
