220 m Altpleistozän im „Heidelberger Loch"
Abstract. The Neckar river passes the Odenwald mountains in a gorge (tectonic uplift) and flows in Heidelberg into the Upper Rhine graben, which sinks here by 0,2 to 0,75 mm/year. In this deltalike voluminous sediment the whole Quarternary is preserved. In the Cold Ages braided rivers spread gravel and sand. In the interglacials a meandering Neckar sedimented loam, sand or thin layers of gravel. In the warm stages from 35 to 7 the curve of the clay content was tuned to the 180-temperature curves of the oceans.
