From diagenesis to anchimetamorphism, upper Austroalpine sedimentary cover in Bavaria and Tyrol

摘要

Vitrinite reflectance and illite crystallinity of a great number of samples of fine-grained Mesozoic sediments from the Northern Calcareous Alpes between Allg#xe4;u and the Karwendel Mountains have been investigated. Coalification varies from 0,4 Rr to 6,2 Rmaxand allows a significant description of the low diagenetic temperature distribution in the greatest part of this area. For most stratigraphiC units, reliable correlations between vitrinite reflectance and illite crystallinity can be established. By means of both methods the fields of diagenesis and anchimetamorphism are subdivided into five stages.
