Caliche-Bildungen auf Höheren Deckenschottern der Nordschweiz?

Abstract. Within the fluvioglaeial deposits of the Höhere Deckenschotter of the Irchel (northern part of canton Zurich, Switzerland) finegrained overhank deposits are preserved in a few places. The overhank deposits and sometimes also the gravels underneath contain calcium-carbonate-precipitates of various shapes and structures. Because of their special appearence and characteristic vertical succesion these precipitates may be interpreted as caliche.
