Profilaufbau, Molluskenführung und Parallelisierungsmöglichkeiten des Altwürmabschnitts im Lössprofil Mainz-Weisenau

Erhard Bibus, Wolfgang Rähle & Joachim Wedel
In the covering loess layers of the quarry of Mainz-Weisenau (Heidelberger Zement AG), three Early Wuermian humic zones (Mosbacher Humuszonen) are exposed above the last interglacial soil. Based on a detailed description of the section, a complete series of samples was collected for malacozoological studies. The evidence of the fossil record is somewhat compromised by displaced sediments under and between the humic zones, and by the possibility of secondary introduction of shells. Nonetheless, the fossil...
