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...

Evolution of Illite/Smectite from Early Diagenesis through Incipient Metamorphism in Sediments of the Basque-Cantabrian Basin
Basque Cantabrian Basin Diagenesis Illite Smectite
2011/12/23
Abstract: Prograde evolution of illite/smectite occurring in an unusually-thick (8000 m) sequence of Mesozoic-Cenozoic sediments in the Basque-Cantabrian Basin, Spain, has been studied using XRD and T...
