Diagenesis and Metamorphism of Clay Minerals in the Helvetic Alps of Eastern Switzerland
Clay mineralogy Diagenesis Helvetic Alps Incipient metamorphism Switzerland
2011/12/1
Abstract: Helvetic sediments from the northern margin of the Alps in eastern Switzerland were studied by clay mineralogical methods. Based on illite “crystallinity” (Kübler index), the study area is d...
