A loess profile near the town of Karlich in the Rhein-land of Western Germany contains various forms of carbonate which are described in detail. A systematic relationship concerning a transition from finely divided grains of carbonate to large complex concretions is given. The stratigraphic presence of three distinct zones of carbonate concretions and the results of analysis for carbonate content in the entire profile are presented as additional evidence for a ternary (and possibly a quaternary) climatic differentiation of the most recent glacial stage in the Middle Rhein region.
