Schalkenmehrener Maar

Schalkenmehren

The Schalkenmehren maars are lined up along a fissure running SE to NW. About 20,000 to 30,000 years ago they erupted: one by one: the dry maar, the low-moor bog, then the water-filled maar, probably a double maar.The fissure which allowed the magma to rise up, breaches numerous Lower Devonian strata. Some are abundant in fossils, such as the Eckfeld layers named after the homonymous maar.
